Abstract

This guide covers all aspects of installing, configuring, and managing Certificate System 9.4 in a Common Criteria environment. It also covers management tasks such as adding users; requesting, renewing, and revoking certificates; publishing CRLs; and managing smart cards. This guide is intended for Certificate System administrators.

Note

This chapter is an overview of Red Hat Certificate System and the various subsystems. For details on evaluated product features, please see the NIAP Product Compliant List at https://www.niap-ccevs.org/Product/PCL.cfm.

Note

Network security services (NSS) and Federal Information Processing Standard (FIPS) hardware security modules (HSM) were the only evaluated cryptographic providers.
Every common PKI operation — issuing, renewing and revoking certificates; archiving and recovering keys; publishing CRLs and verifying certificate status — is carried out by interoperating subsystems within Red Hat Certificate System. The functions of each individual subsystem and the way that they work together to establish a robust and local PKI are described in this chapter.

1.1. Uses for Certificates
Copy link

The purpose of certificates is to establish trust. Their usage varies depending on the kind of trust they are used to ensure. Some kinds of certificates are used to verify the identity of the presenter; others are used to verify that an object or item has not been tampered with.
For information on how certificates are used, the types of certificates, or how certificates establish identities and relationships, see the Certificates and Authentication section in the Red Hat Certificate System Planning, Installation, and Deployment Guide (Common Criteria Edition).

1.2. A Review of Certificate System Subsystems
Copy link

Red Hat Certificate System provides five different subsystems, each focusing on different aspects of a PKI deployment. These subsystems work together to create a public key infrastructure (PKI). Depending on what subsystems are installed, a PKI can function as a token management system (TMS) or a non token management system. For descriptions of the subsystems and TMS and non-TMS environments, see the A Review of Certificate System Subsystems in the Red Hat Certificate System Planning, Installation, and Deployment Guide (Common Criteria Edition).

1.3. A Look at Managing Certificates (Non-TMS)
Copy link

A conventional PKI environment provides the basic framework to manage certificates stored in software databases. This is a non-TMS environment, since it does not manage certificates on smart cards. At a minimum, a non-TMS requires only a CA, but a non-TMS environment can use OCSP responders and KRA instances as well.
For information on this topic, see the following sections in Red Hat Certificate System Planning, Installation, and Deployment Guide (Common Criteria Edition):
  • Managing Certificates
  • Using a Single Certificate Manager
  • Planning for Lost Keys: Key Archival and Recovery
  • Balancing Certificate Request Processing
  • Balancing Client OCSP Requests

1.4. A Look at the Token Management System (TMS)
Copy link

Note

Features in this section on TMS are not tested in the evaluation. This section is for reference only.
Certificate System creates, manages, renews, and revokes certificates, and it also archives and recovers keys. For organizations that use smart cards, the Certificate System has a token management system — a collection of subsystems with established relationships — to generate keys and requests and receive certificates to be used for smart cards.
For information on this topic, see the following sections in Red Hat Certificate System Planning, Installation, and Deployment Guide (Common Criteria Edition):
  • Working with Smart Cards (TMS)
  • Using Smart Cards

1.5. Red Hat Certificate System services
Copy link

There are various different interfaces for managing certificates and subsystems, depending on the user's role: administrators, agents, auditors, and end users. For an overview of the different functions that are performed through each interface, see Red Hat Certificate System User Interfaces section in the Red Hat Certificate System 9 Planning, Installation, and Deployment Guide (Common Criteria Edition).

Chapter 2. User Interfaces
Copy link

There are different interfaces for managing certificates and subsystems, depending on the user's role: administrators, agents, auditors, and end users.

2.1. User Interfaces Overview
Copy link

Administrators can use the following interfaces to securely interact with a completed Certificate System installation:
  • The PKI command-line interface and other command-line utilities
  • The PKI Console graphical interface
  • The Certificate System web interface.
These interfaces require configuration prior to use for secure communication with the Certificate System server over TLS. Using these clients without proper configuration is not allowed. Some of these tools use TLS client authentication. When required, their required initialization procedure includes configuring this. Which interface is used depends on the administrator's preferences and functionality available. Common actions using these interfaces are described in the remainder of the guide after this chapter.
By default, the PKI command-line interface uses the NSS database in the user's ~/.dogtag/nssdb/ directory. Section 2.5.1.1, “pki CLI Initialization” provides detailed steps for initializing the NSS database with the administrator's certificate and key. Some examples of using the PKI command-line utility are described in Section 2.5.1.2, “Using "pki" CLI”. Additional examples are shown through the rest of the guide.
Interfacing with Certificate System (as an administrator in other user roles) can be done using various command-line utilities to submit CMC requests, manage generated certificates, and so on. These are described briefly in Section 2.5, “Command Line Interfaces”, such as Section 2.5.2, “AtoB”. These utilities are utilized in later sections such as Section 5.2.2, “Creating a CSR Using PKCS10Client”.
Certificate System's PKI Console interface is a graphical interface. Section 2.3.1, “pkiconsole Initialization” describes how to initialize it. Section 2.3.2, “Using pkiconsole for CA, OCSP, KRA, and TKS Subsystems” gives an overview of using the console interface. Later sections, such as Section 3.2.2, “Managing Certificate Enrollment Profiles Using the Java-based Administration Console” go into greater detail for specific operations.
The Certificate System web interface allows administrative access through the Firefox web browser. Section 2.4.1, “Browser Initialization” describes instructions about configuring the client authentication. Other sections in Section 2.4, “Web Interface” describe using the web interface of Certificate System. More information about using the browser for specific tasks are included in the rest of the documentation, such as Section 6.2.2.2, “Searching for Certificates (Advanced)”.

Note

To terminate a PKI Console session, click the Exit button. To terminate a web browser session, close the browser. A command-line utility terminates itself as soon as it performs the action and returns to the prompt, so no action is needed on the administrator's part to terminate the session.

2.2. Client NSS Database Initialization
Copy link

On Red Hat Certificate System, certain interfaces may need to access the server using TLS client certificate authentication (mutual authentication). Before performing server-side admin tasks, you need to:
  1. Prepare an NSS database for the client. This can be a new database or an existing one.
  2. Import the CA certificate chain and trust them.
  3. Have a certificate and corresponding key. They can be generated in the NSS database or imported from somewhere else, such as from a PKCS #12 file.
Based on the utility, you need to initialize the NSS database accordingly. See:

2.3. Graphical Interface
Copy link

pkiconsole is a graphical interface that is designed for users with the Administrator role privilege to manage the subsystem itself. This includes adding users, configuring logs, managing profiles and plug-ins, and the internal database, among many other functions. This utility communicates with the Certificate System server via TLS using client-authentication and can be used to manage the server remotely.

2.3.1. pkiconsole Initialization
Copy link

To use the pkiconsole interface for the first time, specify a new password and use the following command: 
$ pki -c password -d ~/.redhat-idm-console client-init
Copy to Clipboard Toggle word wrap
This command creates a new client NSS database in the ~/.redhat-idm-console/ directory.
To import the CA certificate into the PKI client NSS database, see Section 11.2, “Importing a Root Certificate”.
To request a new client certificate, see Chapter 5, Requesting, Enrolling, and Managing Certificates.
Execute the following command to extract the admin client certificate from the .p12 file: 
$ openssl pkcs12 -in file -clcerts -nodes -nokeys -out file.crt
Copy to Clipboard Toggle word wrap
Validate and import the admin client certificate as described in Chapter 11, Managing Certificate/Key Crypto Token: 
$ PKICertImport -d ~/.redhat-idm-console -n "nickname" -t ",," -a -i file.crt -u C
Copy to Clipboard Toggle word wrap

Important

Make sure all intermediate certificates and the root CA certificate have been imported before importing the CA admin client certificate.
To import an existing client certificate and its key into the client NSS database: 
$ pki -c password -d ~/.redhat-idm-console pkcs12-import --pkcs12-file file --pkcs12-password pkcs12-password
Copy to Clipboard Toggle word wrap
Verify the client certificate with the following command: 
$ certutil -V -u C -n "nickname" -d ~/.redhat-idm-console
Copy to Clipboard Toggle word wrap
The Java console is used by four subsystems: the CA, OCSP, KRA, and TKS. The console is accessed using a locally-installed pkiconsole utility. It can access any subsystem because the command requires the host name, the subsystem's administrative TLS port, and the specific subsystem type. 
pkiconsole https://server.example.com:admin_port/subsystem_type
Copy to Clipboard Toggle word wrap
If DNS is not configured, you can use an IPv4 or IPv6 address to connect to the console. For example: 
https://192.0.2.1:8443/ca
https://[2001:DB8::1111]:8443/ca
Copy to Clipboard Toggle word wrap
This opens a console, as in Figure 2.1, “Certificate System Console”.

Figure 2.1. Certificate System Console

The Configuration tab controls all of the setup for the subsystem, as the name implies. The choices available in this tab are different depending on which subsystem type the instance is; the CA has the most options since it has additional configuration for jobs, notifications, and certificate enrollment authentication.
All subsystems have four basic options:
  • Users and groups
  • Access control lists
  • Log configuration
  • Subsystem certificates (meaning the certificates issued to the subsystem for use, for example, in the security domain or audit signing)
The Status tab shows the logs maintained by the subsystem.

Accessing the Web Console
You can access the PKI services by opening https://host_name:port in your browser.

2.4.2. The Administrative Interfaces
Copy link

The all subsystems use HTML-based administrative interface. It is accessed by entering the host name and secure port as the URL, authenticating with the administrator's certificate, and clicking the appropriate Administrators link.

Note

There is a single TLS port for all subsystems which is used for both administrator and agent services. Access to those services is restricted by certificate-based authentication.
The HTML admin interface is much more limited than the Java console; the primary administrative function is managing the subsystem users.
The TPS only allows operations to manage users for the TPS subsystem. However, the TPS admin page can also list tokens and display all activities (including normally-hidden administrative actions) performed on the TPS.
TPS Admin Page

2.4.3. Agent Interfaces
Copy link

The agent services pages are where almost all of the certificate and token management tasks are performed. These services are HTML-based, and agents authenticate to the site using a special agent certificate.
Certificate Manager's Agent Services Page

Certificate Manager's Agent Services Page

Figure 2.3. Certificate Manager's Agent Services Page

The operations vary depending on the subsystem:
  • The Certificate Manager agent services include approving certificate requests (which issues the certificates), revoking certificates, and publishing certificates and CRLs. All certificates issued by the CA can be managed through its agent services page.
  • The TPS agent services, like the CA agent services, manages all of the tokens which have been formatted and have had certificates issued to them through the TPS. Tokens can be enrolled, suspended, and deleted by agents. Two other roles (operator and admin) can view tokens in web services pages, but cannot perform any actions on the tokens.
  • KRA agent services pages process key recovery requests, which set whether to allow a certificate to be issued reusing an existing key pair if the certificate is lost.
  • The OCSP agent services page allows agents to configure CAs which publish CRLs to the OCSP, to load CRLs to the OCSP manually, and to view the state of client OCSP requests.
The TKS is the only subsystem without an agent services page.

2.4.4. End User Pages
Copy link

The CA and TPS both process direct user requests in some way. That means that end users have to have a way to connect with those subsystems. The CA has end-user, or end-entities, HTML services. The TPS uses the Enterprise Security Client.
The end-user services are accessed over standard HTTP using the server's host name and the standard port number; they can also be accessed over HTTPS using the server's host name and the specific end-entities TLS port.
For CAs, each type of TLS certificate is processed through a specific online submission form, called a profile. There are about two dozen certificate profiles for the CA, covering all sorts of certificates — user TLS certificates, server TLS certificates, log and file signing certificates, email certificates, and every kind of subsystem certificate. There can also be custom profiles.

Figure 2.4. Certificate Manager's End-Entities Page

End users retrieve their certificates through the CA pages when the certificates are issued. They can also download CA chains and CRLs and can revoke or renew their certificates through those pages.

2.5. Command Line Interfaces
Copy link

This section discusses command-line utilities.

2.5.1. "pki" CLI
Copy link

The pki command-line interface (CLI) provides access to various services on the server using the REST interface (see the REST Interface section in the Red Hat Certificate System Planning, Installation, and Deployment Guide (Common Criteria Edition)). The CLI can be invoked as follows: 
$ pki [CLI options] <command> [command parameters]
Copy to Clipboard Toggle word wrap
Note that the CLI options must be placed before the command, and the command parameters after the command.
2.5.1.1. pki CLI Initialization
Copy link
To use the command line interface for the first time, specify a new password and use the following command: 
$ pki -c <password> client-init
Copy to Clipboard Toggle word wrap
This will create a new client NSS database in the ~/.dogtag/nssdb directory. The password must be specified in all CLI operations that uses the client NSS database. Alternatively, if the password is stored in a file, you can specify the file using the -C option. For example: 
$ pki -C password_file client-init
Copy to Clipboard Toggle word wrap
To import the CA certificate into the client NSS database refer to Section 11.2, “Importing a Root Certificate”.
Some commands may require client certificate authentication. To import an existing client certificate and its key into the client NSS database, specify the PKCS #12 file and the password, and execute the following command:
Execute the following command to extract the admin client certificate from the .p12 file: 
$ openssl pkcs12 -in file -clcerts -nodes -nokeys -out file.crt
Copy to Clipboard Toggle word wrap
Validate and import the admin client certificate as described in Chapter 11, Managing Certificate/Key Crypto Token: 
$ PKICertImport -d ~/.dogtag/nssdb -n "nickname" -t ",," -a -i file.crt -u C
Copy to Clipboard Toggle word wrap

Important

Make sure all intermediate certificates and the root CA certificate have been imported before importing the CA admin client certificate.
To import an existing client certificate and its key into the client NSS database, specify the PKCS #12 file and the password, and execute the following command: 
$ pki -c <password> pkcs12-import --pkcs12-file <file> --pkcs12-password <password>

Part II. Setting up Certificate Services
Copy link

Note

Modification of CS.cfg, server.xml or any configuration file post-installation is expressly prohibited in a certified environment.
The Certificate System provides a customizable framework to apply policies for incoming certificate requests and to control the input request types and output certificate types; these are called certificate profiles. Certificate profiles set the required information for certificate enrollment forms in the Certificate Manager end-entities page. This chapter describes how to configure certificate profiles.

3.1. About Certificate Profiles
Copy link

A certificate profile defines everything associated with issuing a particular type of certificate, including the authentication method, the authorization method, the default certificate content, constraints for the values of the content, and the contents of the input and output for the certificate profile. Enrollment and renewal requests are submitted to a certificate profile and are then subject to the defaults and constraints set in that certificate profile. These constraints are in place whether the request is submitted through the input form associated with the certificate profile or through other means. The certificate that is issued from a certificate profile request contains the content required by the defaults with the information required by the default parameters. The constraints provide rules for what content is allowed in the certificate.
For details about using and customizing certificate profiles, see Section 3.2, “Setting up Certificate Profiles”.
The Certificate System contains a set of default profiles. While the default profiles are created to satisfy most deployments, every deployment can add their own new certificate profiles or modify the existing profiles.
  • Authentication. In every certification profile can be specified an authentication method.
  • Authorization. In every certification profile can be specified an authorization method.
  • Profile inputs. Profile inputs are parameters and values that are submitted to the CA when a certificate is requested. Profile inputs include public keys for the certificate request and the certificate subject name requested by the end entity for the certificate.
  • Profile outputs. Profile outputs are parameters and values that specify the format in which to provide the certificate to the end entity. Profile outputs are CMC responses which contain a PKCS#7 certificate chain, when the request was successful.
  • Certificate content. Each certificate defines content information, such as the name of the entity to which it is assigned (the subject name), its signing algorithm, and its validity period. What is included in a certificate is defined in the X.509 standard. With version 3 of the X509 standard, certificates can also contain extensions. For more information about certificate extensions, see Section B.3, “Standard X.509 v3 Certificate Extension Reference”.
    All of the information about a certificate profile is defined in the set entry of the profile policy in the profile's configuration file. When multiple certificates are expected to be requested at the same time, multiple set entries can be defined in the profile policy to satisfy needs of each certificate. Each policy set consists of a number of policy rules and each policy rule describes a field in the certificate content. A policy rule can include the following parts:
    • Profile defaults. These are predefined parameters and allowed values for information contained within the certificate. Profile defaults include the validity period of the certificate, and what certificate extensions appear for each type of certificate issued.
    • Profile constraints. Constraints set rules or policies for issuing certificates. Amongst other, profile constraints include rules to require the certificate subject name to have at least one CN component, to set the validity of a certificate to a maximum of 360 days, to define the allowed grace period for renewal, or to require that the subjectaltname extension is always set to true.

3.1.1. The Enrollment Profile
Copy link

The parameters for each profile defining the inputs, outputs, and policy sets are listed in more detail in Table 11.1. Profile Configuration File Parameters in Red Hat Certificate System Planning, Installation and Deployment Guide.
A profile usually contains inputs, policy sets, and outputs, as illustrated in the caUserCert profile in Example 3.1, “Example caCMCUserCert Profile”.

Example 3.1. Example caCMCUserCert Profile

The first part of a certificate profile is the description. This shows the name, long description, whether it is enabled, and who enabled it. 
desc=This certificate profile is for enrolling user certificates by using the CMC certificate request with CMC Signature authentication.
visible=true
enable=true
enableBy=admin
name=Signed CMC-Authenticated User Certificate Enrollment
Copy to Clipboard Toggle word wrap

Note

The missing auth.instance_id= entry in this profile means that with this profile, authentication is not needed to submit the enrollment request. However, manual approval by an authorized CA agent will be required to get an issuance.
Next, the profile lists all of the required inputs for the profile: 
input.list=i1
input.i1.class_id=cmcCertReqInputImp
Copy to Clipboard Toggle word wrap
For the caCMCUserCert profile, this defines the certificate request type, which is CMC.
Next, the profile must define the output, meaning the format of the final certificate. The only one available is certOutputImpl, which results in CMC response to be returned to the requestor in case of success. 
output.list=o1
output.o1.class_id=certOutputImpl
Copy to Clipboard Toggle word wrap
The last — largest — block of configuration is the policy set for the profile. Policy sets list all of the settings that are applied to the final certificate, like its validity period, its renewal settings, and the actions the certificate can be used for. The policyset.list parameter identifies the block name of the policies that apply to one certificate; the policyset.userCertSet.list lists the individual policies to apply.
For example, the sixth policy populates the Key Usage Extension automatically in the certificate, according to the configuration in the policy. It sets the defaults and requires the certificate to use those defaults by setting the constraints: 
policyset.list=userCertSet
policyset.userCertSet.list=1,10,2,3,4,5,6,7,8,9
...
policyset.userCertSet.6.constraint.class_id=keyUsageExtConstraintImpl

An extension configures additional information to include in a certificate or rules about how the certificate can be used. These extensions can either be specified in the certificate request or taken from the profile default definition and then enforced by the constraints.
A certificate extension is added or identified in a profile by adding the default which corresponds to the extension and sets default values, if the certificate extension is not set in the request. For example, the Basic Constraints Extension identifies whether a certificate is a CA signing certificate, the maximum number of subordinate CAs that can be configured under the CA, and whether the extension is critical (required): 
policyset.caCertSet.5.default.name=Basic Constraints Extension Default
policyset.caCertSet.5.default.params.basicConstraintsCritical=true
policyset.caCertSet.5.default.params.basicConstraintsIsCA=true
policyset.caCertSet.5.default.params.basicConstraintsPathLen=-1
Copy to Clipboard Toggle word wrap
The extension can also set required values for the certificate request called constraints. If the contents of a request do not match the set constraints, then the request is rejected. The constraints generally correspond to the extension default, though not always. For example: 
policyset.caCertSet.5.constraint.class_id=basicConstraintsExtConstraintImpl
policyset.caCertSet.5.constraint.name=Basic Constraint Extension Constraint
policyset.caCertSet.5.constraint.params.basicConstraintsCritical=true
policyset.caCertSet.5.constraint.params.basicConstraintsIsCA=true
policyset.caCertSet.5.constraint.params.basicConstraintsMinPathLen=-1
policyset.caCertSet.5.constraint.params.basicConstraintsMaxPathLen=-1

Note

To allow user supplied extensions to be embedded in the certificate requests and ignore the system-defined default in the profile, the profile needs to contain the User Supplied Extension Default, which is described in Section B.1.33, “User Supplied Extension Default”.

3.1.3. Inputs and Outputs
Copy link

Inputs set information that must be submitted to receive a certificate. In a Common Criteria environment, set the input.i1.class_id parameter in all enabled profiles to cmcCertReqInputImpl: 
input.i1.class_id=cmcCertReqInputImpl
Copy to Clipboard Toggle word wrap
The outputs configured in the profile define the format of the certificate that is issued. In a Common Criteria environment, set the output.o1.class_id parameter in all enabled profiles to certOutputImpl: 
output.o1.class_id=CertOutputImpl
Copy to Clipboard Toggle word wrap
In a Common Criteria-compliant Certificate System environment, users access profiles through the /ca/ee/ca/profileSubmitUserSignedCMCFull servlet that is accessed through the end-entities interface.

3.2. Setting up Certificate Profiles
Copy link

In Certificate System, you can add, delete, and modify enrollment profiles:
  • Using the PKI command-line interface
  • Using the Java-based administration console
This section provides information on each method.
This section describes how to manage certificate profiles using the pki utility. For further details, see the pki-ca-profile(1) man page.

Note

Using the raw format is recommended. For details on each attribute and field of the profile, see the section Creating and Editing Certificate Profiles Directly on the File System in Red Hat Certificate System Planning, Installation and Deployment Guide.
Before you can edit a certificate profile, you must disable it. After the modification is complete, you can re-enable the profile.

Note

Only CA agents can enable and disable certificate profiles.
For example, to disable the caCMCECserverCert certificate profile: 
# pki -c password -n caagent ca-profile-disable caCMCECserverCert

Copy to Clipboard Toggle word wrap

Note

In raw format, specify the new profile ID as follows: 
profileId=profile_name

CA administrators can edit a certificate profile in raw format without manually downloading the configuration file.
For example, to edit the caCMCECserverCert profile: 
# pki -c password -n caadmin ca-profile-edit caCMCECserverCert
Copy to Clipboard Toggle word wrap
This command automatically downloads the profile configuration in raw format and opens it in the VI editor. When you close the editor, the profile configuration is updated on the server.
You do not need to restart the CA after editing a profile.

Important

Before you can edit a profile, disable the profile. For details, see Section 3.2.1.1, “Enabling and Disabling a Certificate Profile”.

Example 3.2. Editing a Certificate Profile in RAW Format

For example, to edit the caCMCserverCert profile to accept multiple user-supplied extensions:
  1. Disable the profile as a CA agent: 
    # pki -c password -n caagemt ca-profile-disable caCMCserverCert
    Copy to Clipboard Toggle word wrap
  2. Edit the profile as a CA administrator:
    1. Download and open the profile in the VI editor: 
      # pki -c password -n caadmin ca-profile-edit caCMCserverCert
      Copy to Clipboard Toggle word wrap
    2. Update the configuration to accept the extensions. For details, see Example B.3, “Multiple User Supplied Extensions in CSR”.
  3. Enable the profile as a CA agent:

Important

Before you can delete a profile, disable the profile. For details, see Section 3.2.1.1, “Enabling and Disabling a Certificate Profile”.
For security reasons, the Certificate Systems enforces separation of roles whereby an existing certificate profile can only be edited by an administrator after it was allowed by an agent. To add a new certificate profile or modify an existing certificate profile, perform the following steps as the administrator:
  1. Log in to the Certificate System CA subsystem console. 
    pkiconsole https://server.example.com:8443/ca
    Copy to Clipboard Toggle word wrap
  2. In the Configuration tab, select Certificate Manager, and then select Certificate Profiles.
    The Certificate Profile Instances Management tab, which lists configured certificate profiles, opens.
  3. To create a new certificate profile, click Add.
    In the Select Certificate Profile Plugin Implementation window, select the type of certificate for which the profile is being created.
    View larger image
  4. Fill in the profile information in the Certificate Profile Instance Editor.
    View larger image
    • Certificate Profile Instance ID. This is the ID used by the system to identify the profile.
    • Certificate Profile Name. This is the user-friendly name for the profile.
    • Certificate Profile Description.
    • End User Certificate Profile. This sets whether the request must be made through the input form for the profile. This is usually set to true. Setting this to false allows a signed request to be processed through the Certificate Manager's certificate profile framework, rather than through the input page for the certificate profile.
    • Certificate Profile Authentication. This sets the authentication method. An automated authentication is set by providing the instance ID for the authentication instance. If this field is blank, the authentication method is agent-approved enrollment; the request is submitted to the request queue of the agent services interface.
      Unless it is for a TMS subsystem, administrators must select one of the following authentication plug-ins:
      • CMCAuth: Use this plug-in when a CA agent must approve and submit the enrollment request.
      • CMCUserSignedAuth: Use this plug-in to enable non-agent users to enroll own certificates.
  5. Click OK. The plug-in editor closes, and the new profile is listed in the profiles tab.
  6. Configure the policies, inputs, and outputs for the new profile. Select the new profile from the list, and click Edit/View.
  7. Set up policies in the Policies tab of the Certificate Profile Rule Editor window. The Policies tab lists policies that are already set by default for the profile type.
    1. To add a policy, click Add.
      View larger image
    2. Choose the default from the Default field, choose the constraints associated with that policy in the Constraints field, and click OK.
      View larger image
    3. Fill in the policy set ID. When issuing dual key pairs, separate policy sets define the policies associated with each certificate. Then fill in the certificate profile policy ID, a name or identifier for the certificate profile policy.
    4. Configure any parameters in the Defaults and Constraints tabs.
      View larger image
      Defaults defines attributes that populate the certificate request, which in turn determines the content of the certificate. These can be extensions, validity periods, or other fields contained in the certificates. Constraints defines valid values for the defaults.
      See Section B.1, “Defaults Reference” and Section B.2, “Constraints Reference” for complete details for each default or constraint.
    To modify an existing policy, select a policy, and click Edit. Then edit the default and constraints for that policy.
    To delete a policy, select the policy, and click Delete.
  8. Set inputs in the Inputs tab of the Certificate Profile Rule Editor window. There can be more than one input type for a profile.

    Note

    Unless you configure the profile for a TMS subsystem, select only cmcCertReqInput and delete other profiles by selecting them and clicking the Delete button.
    1. To add an input, click Add.
      View larger image
    2. Choose the input from the list, and click OK. See Section A.1, “Input Reference” for complete details of the default inputs.
    3. The New Certificate Profile Editor window opens. Set the input ID, and click OK.
      View larger image
    Inputs can be added and deleted. It is possible to select edit for an input, but since inputs have no parameters or other settings, there is nothing to configure.
    To delete an input, select the input, and click Delete.
  9. Set up outputs in the Outputs tab of the Certificate Profile Rule Editor window.
    Outputs must be set for any certificate profile that uses an automated authentication method; no output needs to be set for any certificate profile that uses agent-approved authentication. The Certificate Output type is set by default for all profiles and is added automatically to custom profiles.
    Unless you configure the profile for a TMS subsystem, select only certOutput.
    View larger image
    Outputs can be added and deleted. It is possible to select edit for an output, but since outputs have no parameters or other settings, there is nothing to configure.
    1. To add an output, click Add.
    2. Choose the output from the list, and click OK.
    3. Give a name or identifier for the output, and click OK.
      This output will be listed in the output tab. You can edit it to provide values to the parameters in this output.
    To delete an output, select the output from list, and click Delete.
  10. Restart the CA to apply the new profile. 
    systemctl restart pki-tomcatd-nuxwdog@instance_name.service
    Copy to Clipboard Toggle word wrap
  11. After creating the profile as an administrator, a CA agent has to approve the profile in the agent services pages to enable the profile.
    1. Open the CA's services page. 
      https://server.example.com:8443/ca/services
      Copy to Clipboard Toggle word wrap
    2. Click the Manage Certificate Profiles link. This page lists all of the certificate profiles that have been set up by an administrator, both active and inactive.
    3. Click the name of the certificate profile to approve.
    4. At the bottom of the page, click the Enable button.

Note

If this profile will be used with a TPS, then the TPS must be configured to recognized the profile type. This is in 11.1.4. Managing Smart Card CA Profiles in Red Hat Certificate System's Planning, Installation, and Deployment Guide.
Authorization methods for the profiles can only be added to the profile using the command line, as described in the section Creating and Editing Certificate Profiles Directly on the File System in Red Hat Certificate System Planning, Installation and Deployment Guide.
To modify an existing certificate profile:
  1. Log into the agent services pages and disable the profile.
    Once a certificate profile is enabled by an agent, that certificate profile is marked enabled in the Certificate Profile Instance Management tab, and the certificate profile cannot be edited in any way through the console.
  2. Log in to the Certificate System CA subsystem console. 
    pkiconsole https://server.example.com:8443/ca
    Copy to Clipboard Toggle word wrap
  3. In the Configuration tab, select Certificate Manager, and then select Certificate Profiles.
  4. Select the certificate profile, and click Edit/View.
  5. The Certificate Profile Rule Editor window appears. Many any changes to the defaults, constraints, inputs, or outputs.

    Note

    The profile instance ID cannot be modified.
    If necessary, enlarge the window by pulling out one of the corners of the window.
  6. Restart the CA to apply the changes.
  7. In the agent services page, re-enable the profile.

Note

Delete any certificate profiles that will not be approved by an agent. Any certificate profile that appears in the Certificate Profile Instance Management tab also appears in the agent services interface. If a profile has already been enabled, it must be disabled by the agent before it can be deleted from the profile list.

3.2.3. Listing Certificate Enrollment Profiles
Copy link

The following pre-defined certificate profiles are ready to use and set up in this environment when the Certificate System CA is installed. These certificate profiles have been designed for the most common types of certificates, and they provide common defaults, constraints, authentication methods, inputs, and outputs.
For a list of supported profiles, see Section 8.1.2, “CMC Authentication Plug-ins”.
To list the available profiles on the command line, use the pki utility. For example: 
# pki -c password -n caadmin ca-profile-find

3.3. Defining Key Defaults in Profiles
Copy link

When creating certificate profiles, the Key Default must be added before the Subject Key Identifier Default. Certificate System processes the key constraints in the Key Default before creating or applying the Subject Key Identifier Default, so if the key has not been processed yet, setting the key in the subject name fails.
For example, an object-signing profile may define both defaults: 
policyset.set1.p3.constraint.class_id=noConstraintImpl
policyset.set1.p3.constraint.name=No Constraint
policyset.set1.p3.default.class_id=subjectKeyIdentifierExtDefaultImpl
policyset.set1.p3.default.name=Subject Key Identifier Default
...
policyset.set1.p11.constraint.class_id=keyConstraintImpl
policyset.set1.p11.constraint.name=Key Constraint
policyset.set1.p11.constraint.params.keyType=RSA
policyset.set1.p11.constraint.params.keyParameters=1024,2048,3072,4096
policyset.set1.p11.default.class_id=userKeyDefaultImpl
policyset.set1.p11.default.name=Key Default
Copy to Clipboard Toggle word wrap
In the policyset list, then, the Key Default (p11) must be listed before the Subject Key Identifier Default (p3). 
policyset.set1.list=p1,p2,p11,p3,p4,p5,p6,p7,p8,p9,p10

3.4. Configuring Profiles to Enable Renewal
Copy link

Renewing a certificate regenerates the certificate using the same public key as the original certificate. Renewing a certificate can be preferable to simply generating new keys and installing new certificates; for example, if a new CA signing certificate is created, all of the certificates which that CA issued and signed must be reissued. If the CA signing certificate is renewed, than all of the issued certificates are still valid. A renewed certificate is identical to the original, only with an updated validity period and expiration date.
This section discusses how to set up profiles for renewals.

3.4.1. About Renewal
Copy link

A renewed certificate is identical to the original certificate, which makes renewing certificates a much simpler and cleaner option for handling the expiration of many kinds of certificates, especially CA signing certificates.
3.4.1.1. The Renewal Process
Copy link
There are two methods of renewing a certificate. Regenerating the certificate takes the original key, profile, and request of the certificate and recreates a new certificate with a new validity period and expiration date using the identical key. Re-keying a certificate submits a certificate request through the original profile with the same information, so that a new key pair is generated.
A profile that allows renewal is also often accompanied by the renewGracePeriodConstraint entry. For example: 
policyset.cmcUserCertSet.10.constraint.class_id=renewGracePeriodConstraintImpl
policyset.cmcUserCertSet.10.constraint.name=Renewal Grace Period Constraint
policyset.cmcUserCertSet.10.constraint.params.renewal.graceBefore=30
policyset.cmcUserCertSet.10.constraint.params.renewal.graceAfter=30
policyset.cmcUserCertSet.10.default.class_id=noDefaultImpl
policyset.cmcUserCertSet.10.default.name=No Default
Copy to Clipboard Toggle word wrap
3.4.1.1.1. Renewing Using the Same Key
Copy link
A profile that allows the same key to be submitted for renewal has the allowSameKeyRenewal parameter set to true in the uniqueKeyConstraint entry. For example: 
policyset.cmcUserCertSet.9.constraint.class_id=uniqueKeyConstraintImpl
policyset.cmcUserCertSet.9.constraint.name=Unique Key Constraint
policyset.cmcUserCertSet.9.constraint.params.allowSameKeyRenewal=true
policyset.cmcUserCertSet.9.default.class_id=noDefaultImpl
policyset.cmcUserCertSet.9.default.name=No Default
Copy to Clipboard Toggle word wrap
3.4.1.1.2. Renewal Using a New Key
Copy link
To renew a certificate with a new key, use the same profile with a new key. Certificate System uses the subjectDN from the user signing certificate used to sign the request for the new certificate.
The CA's signing certificate can sign the certificates it issues with any public key algorithm supported by the CA. For example, an ECC signing certificate can sign both ECC and RSA certificate requests as long as both ECC and RSA algorithms are supported by the CA. An RSA signing certificate can can sign a PKCS #10 request with EC keys, but may not be able to sign CRMF certificate requests with EC keys if the ECC module is not available for the CA to verify the CRMF proof of possession (POP).
ECC and RSA are public key encryption and signing algorithms. Both public key algorithms support different cipher suites, algorithms used to encrypt and decrypt data. Part of the function of the CA signing certificate is to issue and sign certificates using one of its supported cipher suites.
Each profile can define which cipher suite the CA should use to sign certificates processed through that profile. If no signing algorithm is set, then the profile uses whatever the default signing algorithm is.

3.5.1. Setting the CA's Default Signing Algorithm
Copy link

  1. Open the CA console.

    Copy to Clipboard Toggle word wrap
  2. In the Configuration tab, expand the Certificate Manager tree.
  3. In the General Settings tab, set the algorithm to use in the Algorithm drop-down menu.
    View larger image
Each profile has a Signing Algorithm Default extension defined. The default has two settings: a default algorithm and a list of allowed algorithms, if the certificate request specifies a different algorithm. If no signing algorithms are specified, then the profile uses whatever is set as the default for the CA.
In the profile's .cfg file, the algorithm is set with two parameters: 
policyset.cmcUserCertSet.8.constraint.class_id=signingAlgConstraintImpl
policyset.cmcUserCertSet.8.constraint.name=No Constraint
policyset.cmcUserCertSet.8.constraint.params.signingAlgsAllowed=SHA256withRSA,SHA512withRSA,SHA256withEC,SHA384withRSA,SHA384withEC,SHA512withEC
policyset.cmcUserCertSet.8.default.class_id=signingAlgDefaultImpl
policyset.cmcUserCertSet.8.default.name=Signing Alg
policyset.cmcUserCertSet.8.default.params.signingAlg=-

To configure the Signing Algorithm Default through the console:

Note

Before a profile can be edited, it must first be disabled by an agent.
  1. Open the CA console. 
    pkiconsole https://server.example.com:8443/ca
    Copy to Clipboard Toggle word wrap
  2. In the Configuration tab, expand the Certificate Manager tree.
  3. Click the Certificate Profiles item.
  4. Click the Policies tab.
  5. Select the Signing Alg policy, and click the Edit button.
  6. To set the default signing algorithm, set the value in the Defaults tab. If this is set to -, then the profile uses the CA's default.
    View larger image
  7. To set a list of allowed signing algorithms which can be accepted in a certificate request, open the Constraints tab, and set the list of algorithms in the Value field for signingAlgsAllowed.
    The possible values for the constraint are listed in Section B.2.10, “Signing Algorithm Constraint”.
The subject name of a certificate is a distinguished name (DN) that contains identifying information about the entity to which the certificate is issued. This subject name can be built from standard LDAP directory components, such as common names and organizational units. These components are defined in X.500. In addition to — or even in place of — the subject name, the certificate can have a subject alternative name, which is a kind of extension set for the certificate that includes additional information that is not defined in X.500.
The naming components for both subject names and subject alternative names can be customized.

Important

If the subject name is empty, then the Subject Alternative Name extension must be present and marked critical.
The cn or uid value from a certificate request can be used to build the subject name of the issued certificate. This section demonstrates a profile that requires the naming attribute (CN or UID) being specified in the Subject Name Constraint to be present in the certificate request. If the naming attribute is missing, the request is rejected.
There are two parts to this configuration:
  • The CN or UID format is set in the pattern configuration in the Subject Name Constraint.
  • The format of the subject DN, including the CN or UID token and the specific suffix for the certificate, is set in the Subject Name Default.
For example, to use the CN in the subject DN: 
policyset.serverCertSet.1.constraint.class_id=subjectNameConstraintImpl
policyset.serverCertSet.1.constraint.name=Subject Name Constraint
policyset.serverCertSet.1.constraint.params.pattern=CN=[^,]+,.+
policyset.serverCertSet.1.constraint.params.accept=true
policyset.serverCertSet.1.default.class_id=subjectNameDefaultImpl
policyset.serverCertSet.1.default.name=Subject Name Default
policyset.serverCertSet.1.default.params.name=CN=$request.req_subject_name.cn$,DC=example, DC=com
Copy to Clipboard Toggle word wrap
In this example, if a request comes in with the CN of cn=John Smith, then the certificate will be issued with a subject DN of cn=John Smith,DC=example, DC=com. If the request comes in but it has a UID of uid=jsmith and no CN, then the request is rejected.
The same configuration is used to pull the requester UID into the subject DN: 
policyset.serverCertSet.1.constraint.class_id=subjectNameConstraintImpl
policyset.serverCertSet.1.constraint.name=Subject Name Constraint
policyset.serverCertSet.1.constraint.params.pattern=UID=[^,]+,.+
policyset.serverCertSet.1.constraint.params.accept=true
policyset.serverCertSet.1.default.class_id=subjectNameDefaultImpl
policyset.serverCertSet.1.default.name=Subject Name Default
policyset.serverCertSet.1.default.params.name=UID=$request.req_subject_name.uid$,DC=example, DC=com
Copy to Clipboard Toggle word wrap
The format for the pattern parameter is covered in Section B.2.11, “Subject Name Constraint” and Section B.1.28, “Subject Name Default”.
Information from an LDAP directory or that was submitted by the requester can be inserted into the subject alternative name of the certificate by using matching variables in the Subject Alt Name Extension Default configuration. This default sets the type (format) of information and then the matching pattern (variable) to use to retrieve the information. For example: 
policyset.userCertSet.8.default.class_id=subjectAltNameExtDefaultImpl
policyset.userCertSet.8.default.name=Subject Alt Name Constraint
policyset.userCertSet.8.default.params.subjAltNameExtCritical=false
policyset.userCertSet.8.default.params.subjAltExtType_0=RFC822Name
policyset.userCertSet.8.default.params.subjAltExtPattern_0=$request.requestor_email$
policyset.userCertSet.8.default.params.subjAltExtGNEnable_0=true
Copy to Clipboard Toggle word wrap
This inserts the requester's email as the first CN component in the subject alt name. To use additional components, increment the Type_, Pattern_, and Enable_ values numerically, such as Type_1.
Configuring the subject alt name is detailed in Section B.1.24, “Subject Alternative Name Extension Default”, as well.
To insert LDAP components into the subject alt name of the certificate:
  1. Inserting LDAP attribute values requires enabling the user directory authentication plug-in, SharedSecret.
    1. Open the CA Console.

    3. In the Authentication Instance tab, click Add, and add an instance of the SharedSecret authentication plug-in.
    4. Enter the following information: 
      Authentication InstanceID=SharedToken
shrTokAttr=shrTok
ldap.ldapconn.host=server.example.com
ldap.ldapconn.port=636
ldap.ldapconn.secureConn=true
ldap.ldapauth.bindDN=cn=Directory Manager
password=password
ldap.ldapauth.authtype=BasicAuth
ldap.basedn=ou=People,dc=example,dc=org
      Copy to Clipboard Toggle word wrap
    5. Save the new plug-in instance.
    For information on setting a CMC shared token, see Section 8.1.3.2, “Setting a CMC Shared Secret”.
  2. The ldapStringAttributes parameter instructs the authentication plug-in to read the value of the mail attribute from the user's LDAP entry and put that value in the certificate request. When the value is in the request, the certificate profile policy can be set to insert that value for an extension value.
    The format for the dnpattern parameter is covered in Section B.2.11, “Subject Name Constraint” and Section B.1.28, “Subject Name Default”.
  3. To enable the CA to insert the LDAP attribute value in the certificate extension, edit the profile's configuration file, and insert a policy set parameter for an extension. For example, to insert the mail attribute value in the Subject Alternative Name extension in the caFullCMCSharedTokenCert profile, change the following code: 
    policyset.setID.8.default.params.subjAltExtPattern_0=$request.auth_token.mail[0]$
    Copy to Clipboard Toggle word wrap
    For more details about editing a profile, see Section 3.2.1.3, “Editing a Certificate Profile in Raw Format”.
  4. Restart the CA. 
    systemctl restart pki-tomcatd-nuxwdog@instance_name.service
    Copy to Clipboard Toggle word wrap
For this example, certificates submitted through the caFullCMCSharedTokenCert profile enrollment form will have the Subject Alternative Name extension added with the value of the requester's mail LDAP attribute. For example: 
Identifier: Subject Alternative Name - 2.5.29.17
    Critical: no
    Value:
    RFC822Name: jsmith@example.com
Copy to Clipboard Toggle word wrap
There are many attributes which can be automatically inserted into certificates by being set as a token ($X$) in any of the Pattern_ parameters in the policy set. The common tokens are listed in Table 3.1, “Variables Used to Populate Certificates”, and the default profiles contain examples for how these tokens are used.

$request.subject$ Used when the request was submitted by TPS. The subject name DN of the entity to which TPS has resolved and requested for. For example, cn=John.Smith.123456789,o=TMS Org

3.7.3. Using the CN Attribute in the SAN Extension
Copy link

Several client applications and libraries no longer support using the Common Name (CN) attribute of the Subject DN for domain name validation, which has been deprecated in RFC 2818. Instead, these applications and libraries use the dNSName Subject Alternative Name (SAN) value in the certificate request.
Certificate System copies the CN only if it matches the preferred name syntax according to RFC 1034 Section 3.5 and has more than one component. Additionally, existing SAN values are preserved. For example, the dNSName value based on the CN is appended to existing SANs.
To configure Certificate System to automatically use the CN attribute in the SAN extension, edit the certificate profile used to issue the certificates. For example:
  1. Disable the profile: 
    # pki -c password -p 8080 \
     -n "PKI Administrator for example.com" ca-profile-disable profile_name
    Copy to Clipboard Toggle word wrap
  2. Edit the profile: 
    # pki -c password -p 8080 \
     -n "PKI Administrator for example.com" ca-profile-edit profile_name
    Copy to Clipboard Toggle word wrap
    1. Add the following configuration with a unique set number for the profile. For example: 
      policyset.serverCertSet.12.constraint.class_id=noConstraintImpl
policyset.serverCertSet.12.constraint.name=No Constraint
policyset.serverCertSet.12.default.class_id=commonNameToSANDefaultImpl
policyset.serverCertSet.12.default.name=Copy Common Name to Subject
      Copy to Clipboard Toggle word wrap
      The previous example uses 12 as the set number.
    2. Append the new policy set number to the policyset.userCertSet.list parameter. For example: 
      policyset.userCertSet.list=1,10,2,3,4,5,6,7,8,9,12
      Copy to Clipboard Toggle word wrap
    3. Save the profile.
  3. Enable the profile: 
    # pki -c password -p 8080 \
     -n "PKI Administrator for example.com" ca-profile-enable profile_name
    Copy to Clipboard Toggle word wrap

Note

All default server profiles contain the commonNameToSANDefaultImpl default.

3.7.4. Accepting SAN Extensions from a CSR
Copy link

In certain environments, administrators want to allow specifying Subject Alternative Name (SAN) extensions in Certificate Signing Request (CSR).
To allow retrieving SANs from a CSR, use the User Extension Default. For details, see Section B.1.33, “User Supplied Extension Default”.

Note

A SAN extension can contain one or more SANs.
To accept SANs from a CSR, add the following default and constraint to a profile, such as caCMCECserverCert: 
prefix.constraint.class_id=noConstraintImpl
prefix.constraint.name=No Constraint

prefix.default.class_id=userExtensionDefaultImpl
prefix.default.name=User supplied extension in CSR
prefix.default.params.userExtOID=2.5.29.17

After generating the CSR, follow the steps described in Section 5.3.1, “The CMC Enrollment Process” to complete the CMC enrollment.

Chapter 4. Setting up Key Archival and Recovery
Copy link

This chapter explains how to use the Key Recovery Authority (KRA), previously known as Data Recovery Manager (DRM), to archive private keys and to recover these archived keys to restore encrypted data.

Note

Server-side key generation is an option provided for smart card enrollments performed through the TPS subsystem. This chapter deals with archiving keys through client-side key generation, not the server-side key generation and archivals initiated through the TPS.

Note

Gemalto SafeNet LunaSA only supports PKI private key extraction in its CKE - Key Export model, and only in non-FIPS mode. The LunaSA Cloning model and the CKE model in FIPS mode do not support PKI private key extraction.
Archiving private keys offers protection for users, and for information, if that key is ever lost. Information is encrypted by the public key when it is stored. The corresponding private key must be available to decrypt the information. If the private key is lost, the data cannot be retrieved. A private key can be lost because of a hardware failure or because the key's owner forgets the password or loses the hardware token in which the key is stored. Similarly, encrypted data cannot be retrieved if the owner of the key is unavailable to supply it.

Note

In a cloned environment, it is necessary to set up key archival and recovery manually.

4.1. About Key Archival and Recovery
Copy link

From the end user perspective, key archival requires only two things: a client, such as the pki utility, which can generate a key and a certificate profile which is configured to support key archival. For details about the pki utility, see the Command-Line Interface (CLI) section in the Red Hat Certificate System Planning, Installation, and Deployment Guide (Common Criteria Edition).

4.1.1. Key Archival
Copy link

If an end entity loses a private encryption key or is unavailable to use the private key, the key must be recovered before any data that was encrypted with the corresponding public key can be read. Recovery is possible if the private key was archived when the key was generated.
The KRA stores private encryption keys in a secure key repository in its internal database in form of key records. The Certificate Manager automatically forwards certificate requests issued by a client to the KRA, if the requests contain the key archival option. In such a case, the private key is wrapped by the KRA transport key on the client and sent as an encrypted blob to the KRA. The KRA decrypts the blob and re-encrypts the key using its storage key. The KRA then gives the encrypted blob a unique key identifier and archives it in its key repository as a key record.
The archived copy of the key remains wrapped with the KRA's storage key. It can be decrypted, or unwrapped, only by using the corresponding private key pair of the storage certificate. A combination of one or more key recovery (or KRA) agents' certificates authorizes the KRA to complete the key recovery to retrieve its private storage key and use it to decrypt/recover an archived private key. The KRA indexes stored keys by key number, owner name, and a hash of the public key, allowing for highly efficient searching.
Figure 4.1, “How the Key Archival Process Works” illustrates how the key archival process occurs when an end entity requests a certificate.
How the Key Archival Process Works
View larger image
How the Key Archival Process Works

Figure 4.1. How the Key Archival Process Works

  1. The client generates and encrypts its private key and submits the request to the CA.
  2. After approving the certificate request and issuing the certificate, the Certificate Manager sends it to the KRA for storage, along with the public key. The Certificate Manager waits for verification from the KRA that the private key has been received and stored and that it corresponds to the public encryption key.
  3. The KRA decrypts it with the transport private key. After confirming that the private encryption key corresponds to the public encryption key, the KRA encrypts it again with its public key pair of the storage key before storing it in its internal database.
  4. Once the private encryption key has been successfully stored, the KRA uses the private key of its transport key pair to sign a token confirming that the key has been successfully stored; the KRA then sends the token to the Certificate Manager.
  5. The Certificate Manager issues the certificate, which is embedded in the CMC response.
Both subsystems subject the request to configured certificate profile constraints at appropriate stages. If the request fails to meet any of the profile constraints, the subsystem rejects the request.
The KRA supports agent-initiated key recovery, when designated recovery agents use the key recovery form on the KRA agent services page to process and approve key recovery requests. With the approval of a specified number of agents, an organization can recover keys when the key's owner is unavailable or when keys have been lost.
Certificate System 9 uses an m-of-n ACL-based recovery scheme, rather than an older secret-splitting-based recovery scheme. In versions of Certificate System older than 7.1, the password for the storage token was split and protected by individual recovery agent passwords. Now, Certificate System uses its existing access control scheme to ensure recovery agents are appropriately authenticated over TLS and requires that the agent belong to a specific recovery agent group, by default the Key Recovery Authority Agents Group. The recovery request is executed only when m-of-n (a required number of) recovery agents have granted authorization to the request.
The key recovery scheme can be changed by changing the KRA configuration, as described in the Setting up Agent-Approved Key Recovery Schemes section in the Red Hat Certificate System Planning, Installation, and Deployment Guide (Common Criteria Edition).
For the actual key recovery process, one of the key recovery agents informs all required recovery agents about an impending key recovery and initiates the recovery process in the KRA's agent pages. A key recovery process can either be synchronous, meaning that the initial session must remain open as approvals come in, or asynchronous, meaning that snapshots of the recovery process are stored in the internal database and updated as approvals come in.
Async and Sync Recovery, Side by Side

Async and Sync Recovery, Side by Side

Figure 4.2. Async and Sync Recovery, Side by Side

Important

Synchronous recovery is deprecated in Red Hat Certificate System.
For asynchronous recovery, each step is saved to the internal database. Agents can search for the key to recover and then click the Grant Recovery button to approve the recovery. Asynchronous recoveries will persist even if the KRA is restarted.

4.1.2. Key Recovery
Copy link

To test whether a key can be successfully archived and recovered:
  1. Generate a CRMF request and submit it through the CA’s enrollment portal.
    For more information, see Section 5.3.2.3.1, “Example on Obtaining an Encryption-only certificate with Key Archival”.
  2. Import the certificates into an email client capable of doing SMIME.
  3. Confirm that the key has been archived. In the KRA's agent services page, select Show completed requests. If the key has been archived successfully, there will be information about that key. If the key is not shown, check the logs, and correct the problem. If the key has been successfully archived, close the browser window.
  4. Verify the key. Send a signed and encrypted email. When the email is received, open it, and check the message to see if it is signed and encrypted. There should be a security icon at the top-right corner of the message window that indicates that the message is signed and encrypted.
  5. Delete the certificate. Check the encrypted email again; the mail client should not be able to decrypt the message.
  6. Test whether an archived key can be recovered successfully:
    1. Open the KRA's agent services page, and click the Recover Keys link. Search for the key by the key owner, serial number, or public key. If the key has been archived successfully, the key information will be shown.
    2. Click Recover.
    3. In the form that appears, enter the base-64 encoded certificate that corresponds to the private key to recover; use the CA to get this information. If the archived key was searched for by providing the base-64 encoded certificate, then the certificate does not have to be supplied here.
    4. Make sure that the Async Recovery checkbox is selected to allow the browser session to be closed while recovery is ongoing.
    5. Depending on the agent scheme, a specified number of agents must authorize this key recovery. Have the agents search for the key to recover and then to approve the initiated recovery.
    6. Once all the agents have authorized the recovery, the next screen requests a password to encrypt the PKCS #12 file with the certificate.
    7. The next screen returns a link to download a PKCS #12 blob containing the recovered key pair. Follow the link, and save the blob to file.

      Important

      Opening the PKCS #12 file directly from the browser in the gcr-viewer utility can fail in certain situations. To work around the problem, download the file and manually open it in gcr-viewer.
  7. Restore the key to the browser's database. Import the .p12 file into the browser and mail client.
  8. Open the test email. The message should be shown again.
Certificates are requested and used by end users. Although certificate enrollment and renewal are operations that are not limited to administrators, understanding the enrollment and renewal processes can make it easier for administrators to manage and create appropriate certificate profiles, as described in Section 3.2, “Setting up Certificate Profiles”, and to use fitting authentication methods for each certificate type.
This chapter discusses requesting, receiving, and renewing certificates for use outside Certificate System. For information on requesting and renewing Certificate System subsystem certificates, see Chapter 14, Managing Subsystem Certificates.

5.1. About Enrolling and Renewing Certificates
Copy link

Enrollment is the process for requesting and receiving a certificate. The mechanics for the enrollment process are slightly different depending on the type of certificate, the method for generating its key pair, and the method for generating and approving the certificate itself. Whatever the specific method, certificate enrollment, at a high level, has the same basic steps:
  1. A user generates a certificate request.
  2. The certificate request is submitted to the CA.
  3. The request is verified by authenticating the entity which requested it and by confirming that the request meets the certificate profile rules which were used to submit it.
  4. The request is approved.
  5. The user retrieves the new certificate.
When the certificate reaches the end of its validity period, it can be renewed.

5.2. Creating Certificate Signing Requests
Copy link

As explained in the Enrolling with CMC section in the Red Hat Certificate System Planning, Installation, and Deployment Guide (Common Criteria Edition), the CMCRequest utility accepts Certificate Signing Requests (CSR) in PKCS #10 and CRMF format.
Red Hat Certificate System supports using the following utilities to create CSRs:
  • certutil: Supports creating PKCS #10 requests.
  • PKCS10Client: Supports creating PKCS #10 requests.
  • CRMFPopClient: Supports creating CRMF requests.
The following sections provide some examples on how to use these utilities with the feature-rich enrollment profile framework.

Use the following general procedure to request and issue a certificate using CMC:
  1. Create a Certificate Signing Request (CSR) in one of the following formats:
    • PKCS #10 format
    • Certificate Request Message Format (CRMF) format:
    For details about creating CSRs in these formats, see Section 5.2, “Creating Certificate Signing Requests”.
  2. Import the admin certificate into the client NSS database. For example:
    • Execute the command below to extract the admin client certificate from the .p12 file: 
      $ openssl pkcs12 -in /root/.dogtag/instance/ca_admin_cert.p12 -clcerts -nodes -nokeys -out /root/.dogtag/instance/ca_admin_cert.crt
      Copy to Clipboard Toggle word wrap
    • Validate and import the admin client certificate according to guidance in ⁠Chapter 11, Managing Certificate/Key Crypto Token: 
      $ PKICertImport -d . -n "CA Admin - Client Certificate" -t ",," -a -i /root/.dogtag/instance/ca_admin_cert.crt -u C
      Copy to Clipboard Toggle word wrap

      Important

      Make sure all intermediate certificates and the root CA certificate have been imported before importing the CA Admin client certificate.
    • Import the private keys associated with the certificates. 
      $ pki -c password pkcs12-import --pkcs12-file /root/.dogtag/instance/ca_admin_cert.p12 --pkcs12-password-file /root/.dogtag/instance/ca/pkcs12_password.conf
      Copy to Clipboard Toggle word wrap
  3. Create a configuration file for a CMC request, such as /home/user_name/cmc-request.cfg, with the following content: 
    # NSS database directory where CA agent certificate is stored
dbdir=/home/user_name/.dogtag/nssdb/

# NSS database password
password=password

# Token name (default is internal)
tokenname=internal

# Nickname for signing certificate
nickname=subsystem_admin

# Request format: pkcs10 or crmf
format=pkcs10

# Total number of PKCS10/CRMF requests
numRequests=1

# Path to the PKCS10/CRMF request
# The content must be in Base-64 encoded format.
# Multiple files are supported. They must be separated by space.
input=/home/user_name/file.csr

# Path for the CMC request
output=/home/user_name/cmc-request.bin
    Copy to Clipboard Toggle word wrap
    For further details, see the CMCRequest(1) man page.
  4. Create the CMC request: 
    $ CMCRequest /home/user_name/cmc-request.cfg
    Copy to Clipboard Toggle word wrap
    If the command succeeds, the CMCRequest utility stored the CMC request in the file specified in the output parameter in the request configuration file.
  5. Create a configuration file for HttpClient, such as /home/user_name/cmc-submit.cfg, which you use in a later step to submit the CMC request to the CA. Add the following content to the created file: 
    # PKI server host name
host=server.example.com

# PKI server port number
port=8443

# Use secure connection
secure=true

# Use client authentication
clientmode=true

# NSS database directory where the CA agent certificate is stored.
dbdir=/home/user_name/.dogtag/nssdb/

# NSS database password
password=password

# Token name (default: internal)
tokenname=internal

# Nickname of signing certificate
nickname=subsystem_admin

# Path for the CMC request
input=/home/user_name/cmc-request.bin

# Path for the CMC response
output=/home/user_name/cmc-response.bin
    Copy to Clipboard Toggle word wrap

    Important

    The nickname of the certificate specified in the nickname parameter must match the one previously used for the CMC request.
  6. Depending on what type of certificate you request, add the following parameter to the configuration file created in the previous step: 
    servlet=/ca/ee/ca/profileSubmitCMCFull?profileId=profile_name
    Copy to Clipboard Toggle word wrap
    For example, for a CA signing certificate: 
    servlet=/ca/ee/ca/profileSubmitCMCFull?profileId=caCMCcaCert
    Copy to Clipboard Toggle word wrap

    Important

    When an agent submits the CMC request in the next step, the profile specified in this parameter must use the CMCAuth authentication plug-in. Whereas in user-initiated enrollments, the profile must use the CMCUserSignedAuth plug-in. For further details, see Section 8.1.2, “CMC Authentication Plug-ins”.
  7. Submit the CMC request to the CA: 
    $ HttpClient /home/user_name/cmc-submit.cfg
    Copy to Clipboard Toggle word wrap
  8. To convert the CMC response to a PKCS #7 certificate chain, pass the CMC response file to the -i parameter of the CMCResponse utility. For example: 
    $ CMCResponse -i /home/user_name/cmc-response.bin -o /home/user_name/cert_chain.crt
    Copy to Clipboard Toggle word wrap

5.3.2. Practical CMC Enrollment Scenarios
Copy link

This section describes frequent practical usage scenarios and their workflows to enable CA administrators to decide which CMC method to use in which situation.
For a general process of enrolling a certificate using CMC, see Section 5.3.1, “The CMC Enrollment Process”.
5.3.2.1. Obtaining System and Server Certificates
Copy link
If a service, such as LDAP or a web server, requires a TLS server certificate, the administrator of this server creates a CSR based on the documentation of the service and sends it to the CA's agent for approval. Use the procedure described in Section 5.3.1, “The CMC Enrollment Process” for this process. Additionally, consider the following requirements:
Enrollment Profiles
The agent must either use one of the existing CMC profiles listed in Section 8.1.2, “CMC Authentication Plug-ins” or, alternatively, create a custom profile that uses the CMCAuth authentication mechanism.
CMC Signing Certificate
For system certificates, the CA agent must generate and sign the CMC request. For this, set the nickname parameter in the CMCRequest configuration file to the nickname of the CA agent.

Note

The CA agent must have access to its own private key.
HttpClient TLS Client Nickname
Use the same certificate for signing in the CMCRequest utility's configuration file as for TLS client authentication in the configuration file for HttpClient.
HttpClient servlet Parameter
The servlet in the configuration file passed to the HttpClient utility refers to the CMC servlet and the enrollment profile which handles the request.
Depending on what type of certificate you request, add one of the following entries to the configuration file created in the previous step:
  • For a CA signing certificate: 
    servlet=/ca/ee/ca/profileSubmitCMCFull?profileId=caCMCcaCert
    Copy to Clipboard Toggle word wrap
  • For a KRA transport certificate: 
    servlet=/ca/ee/ca/profileSubmitCMCFull?profileId=caCMCkraTransportCert
    Copy to Clipboard Toggle word wrap
  • For a OCSP signing certificate: 
    servlet=/ca/ee/ca/profileSubmitCMCFull?profileId=caCMCocspCert
    Copy to Clipboard Toggle word wrap
  • For a audit signing certificate: 
    servlet=/ca/ee/ca/profileSubmitCMCFull?profileId=caCMCauditSigningCert
    Copy to Clipboard Toggle word wrap
  • For a subsystem certificate:
    • For RSA certificates: 
      servlet=/ca/ee/ca/profileSubmitCMCFull?profileId=caCMCsubsystemCert
      Copy to Clipboard Toggle word wrap
    • For ECC certificates: 
      servlet=/ca/ee/ca/profileSubmitCMCFull?profileId=caCMCECCsubsystemCert
      Copy to Clipboard Toggle word wrap
  • For a TLS server certificate:
    • For RSA certificates: 
      servlet=/ca/ee/ca/profileSubmitCMCFull?profileId=caCMCserverCert
      Copy to Clipboard Toggle word wrap
    • For ECC certificates: 
      servlet=/ca/ee/ca/profileSubmitCMCFull?profileId=caCMCECCserverCert
      Copy to Clipboard Toggle word wrap
  • For an admin certificate: 
    servlet=/ca/ee/ca/profileSubmitCMCFull?profileId=caFullCMCUserCert
    Copy to Clipboard Toggle word wrap
Further details:
  • When an agent pre-signs a CSR, the Proof of Identification is considered established because the agent examines the CSR for identification. No additional CMC-specific identification proof is required.
  • PKCS #10 files already provide Proof of Possession information and no additional Proof of Possession (POP) is required.
  • In agent pre-approved requests, the PopLinkWittnessV2 feature must be disabled because the identification is checked by the agent.
There are two ways to approve a user's first signing certificate:
The process for signing a CMC request with an agent certificate is the same as for system and server certificates described in Section 5.3.2.1, “Obtaining System and Server Certificates”. The only difference is that the user creates the CSR and sends it to a CA agent for approval.
When a user wants to obtain the first signing certificate and the agent cannot approve the request as described in Section 5.3.2.2.1, “Signing a CMC Request with an Agent Certificate”, you can use a Shared Token. With this token, the user can obtain the first signing certificate. This certificate can then be used to sign other certificates of the user.
In this scenario, use the Shared Secret mechanism to obtain the first signing certificate of the user. Use the following information together with Section 5.3.1, “The CMC Enrollment Process”:
  1. Create a Shared Token either as the user or CA administrator. For details, see Section 8.1.3.1, “Creating a Shared Secret Token”.
    Note that:
    • If the user created the token, the user must send the token to the CA administrator.
    • If the CA administrator created the token, the administrator must share the password used to generate the token with the user. Use a secure way to transmit the password.
  2. As the CA administrator, add the Shared Token to the user entry in LDAP. For details, see Section 8.1.3.2.1, “Adding a CMC Shared Secret to a User Entry for Certificate Enrollment” and the Enabling the CMC Shared Secret Feature section in the Red Hat Certificate System Planning, Installation, and Deployment Guide (Common Criteria Edition).
  3. Use the following parameters in the configuration file passed to the CMCRequest utility:
    • identification.enable
    • witness.sharedSecret
    • identityProofV2.enable
    • identityProofV2.hashAlg
    • identityProofV2.macAlg
    • request.useSharedSecret
    • request.privKeyId
  4. If required by the CA, additionally use the following parameters in the configuration file passed to the CMCRequest utility:
    • popLinkWitnessV2.enable
    • popLinkWitnessV2.keyGenAlg
    • popLinkWitnessV2.macAlg
This section describes the workflow for obtaining an encryption-only certificate which is signed with an existing user signing certificate:

Note

If a user owns multiple certificates for different usages, where one is signing, the user must obtain the signing certificate first. Once the user owns a signing certificate, it can be used for Proof Of Origin without requiring to set up and rely on the CMC Shared Secret mechanism.
For details about obtaining a user's first signing certificate, see Section 5.3.2.2, “Obtaining the First Signing Certificate for a User”.
As a user:
  1. Use the cryptographic token stored in a Network Security Services (NSS) database or on a smart card that contains the user's signing certificate and keys.
  2. Generate the CSR in PKCS #10 or the CRMF format.

    Note

    Use the CRMF format, if key archival is required.
  3. Generate the CMC request.
    Since this is an encryption-only certificate, the private key is not able to sign. Therefore, Proof Of Possession (POP) is not included. For this reason, the enrollment requires two steps: If the initial request is successful, results in a CMC status with the EncryptedPOP control. The user then uses the response and generates a CMC request that contains the DecryptedPOP control and submits it in the second step.
    1. For the first step, in addition to the default parameters, the user must set the following parameters in the configuration file passed to the CMCRequest utility:
      • identification.enable
      • witness.sharedSecret
      • identityProofV2.enable
      • identityProofV2.hashAlg
      • identityProofV2.macAlg
      • popLinkWitnessV2.enable if required by the CA
      • popLinkWitnessV2.keyGenAlg if required by the CA
      • popLinkWitnessV2.macAlg if required by the CA
      • request.privKeyId
      For details, see the CMCRequest(1) man page.
      The response contains:
      • A CMC encrypted POP control
      • The CMCStatusInfoV2 control with the POP required error
      • The request ID
    2. For the second step, in addition to the default parameters, the user must set the following parameters in the configuration file passed to the CMCRequest utility:
      • decryptedPop.enable
      • encryptedPopResponseFile
      • decryptedPopRequestFile
      • request.privKeyId
      For details, see the CMCRequest(1) man page.
To perform an enrollment with key archival, generate a CMC request that contains the user's encrypted private key in the CRMF request. The following procedure assumes that the user already owns a signing certificate. The nickname of this signing certificate is set in the configuration files in the procedure.

Note

The following procedure describes the two-trip issuance used with encryption-only keys, which cannot be used for signing. If you use a key which can sign certificates, pass the -q POP_SUCCESS option instead of -q POP_NONE to the CRMFPopClient utility for a single-trip issuance.
For instructions about using CRMFPoPClient with POP_SUCCESS, see Section 5.2.3.1, “Using CRMFPopClient to Create a CSR with Key Archival” and Section 5.2.3.2, “Using CRMFPopClient to Create a CSR for SharedSecret-based CMC”.
  1. Search for the KRA transport certificate. For example: 
    $ pki cert-find --name KRA_transport_certificate_subject_CN
    Copy to Clipboard Toggle word wrap
  2. Use the serial number of the KRA transport certificate, which you retrieved in the previous step, to store the certificate in a file. For example, to store the certificate with the 12345 serial number in the /home/user_name/kra.cert file: 
    $ pki cert-show 12345 --output /home/user_name/kra.cert
    Copy to Clipboard Toggle word wrap
  3. Use the CRMFPopClient utility to:
    • Create a CSR with key archival:
      1. Change to the certificate database directory of the user or entity for which the certificate is being requested, for example: 
        $ cd /home/user_name/
        Copy to Clipboard Toggle word wrap
      2. Use the CRMFPopClient utility to create a CRMF request, where the RSA private key is wrapped by the KRA transport certificate. For example, to store the request in the /home/user_name/crmf.req file: 
        $ CRMFPopClient -d . -p token_password -n subject_DN -q POP_NONE \
     -b /home/user_name/kra.cert -w "AES/CBC/PKCS5Padding" \
     -v -o /home/user_name/crmf.req
        Copy to Clipboard Toggle word wrap
        Note the ID of the private key displayed by the command. The ID is required in a later step as value in the request.privKeyId parameter in the configuration file for the second trip.
  4. Create a configuration file for the CRMRequest utility, such as /home/user_name/cmc.cfg with the following content: 
    #numRequests: Total number of PKCS10 requests or CRMF requests.
numRequests=1

#input: full path for the PKCS10 request or CRMF request,
#the content must be in Base-64 encoded format
input=/home/user_name/crmf.req

#output: full path for the CMC request in binary format
output=/home/user_name/cmc.req

#tokenname: name of token where agent signing cert can be found

#nickname: nickname for user certificate which will be used
#to sign the CMC full request.
nickname=signing_certificate

#dbdir: directory for cert8.db, key3.db and secmod.db
dbdir=/home/user_name/.dogtag/nssdb/

#password: password for cert8.db which stores the agent certificate
password=password

#format: request format, either pkcs10 or crmf
format=crmf
    Copy to Clipboard Toggle word wrap
  5. Create the CMC request: 
    $ CMCRequest /home/user_name/cmc.cfg
    Copy to Clipboard Toggle word wrap
    If the command succeeds, the CMCRequest utility stored the CMC request in the file specified in the output parameter in the request configuration file.
  6. Create a configuration file for HttpClient, such as /home/user_name/cmc-submit.cfg, which you use in a later step to submit the CMC request to the CA. Add the following content to the created file: 
    #host: host name for the http server
host=server.example.com

#port: port number
port=8443

#secure: true for secure connection, false for nonsecure connection
secure=true

#input: full path for the enrollment request, the content must be in
#binary format
input=/home/user_name/cmc.req

#output: full path for the response in binary format
output=/home/user_name/cmc-response_round_1.bin

#tokenname: name of token where TLS client authentication cert can be found
#(default is internal)
#This parameter will be ignored if secure=false
tokenname=internal

#dbdir: directory for cert8.db, key3.db and secmod.db
#This parameter will be ignored if secure=false
dbdir=/home/user_name/.dogtag/nssdb/

#clientmode: true for client authentication, false for no client authentication

  7. Submit the CMC request to the CA: 
    $ HttpClient /home/user_name/cmc-submit.cfg
    Copy to Clipboard Toggle word wrap
    If the command succeeds, the HTTPClient utility stored the CMC response in the file specified in the output parameter in the configuration file.
  8. Verify the response by passing the response file to the CMCResponse utility. For example: 
    $ CMCResponse -d /home/user_name/.dogtag/nssdb/ -i /home/user_name/cmc-response_round_1.bin
    Copy to Clipboard Toggle word wrap
    If the first trip was successful, CMCResponse displays output similar to the following:

5.4. Renewing Certificates
Copy link

This section explains how to use the different types of certificate renewal described in Section 3.4.1, “About Renewal”. You can use the methods described in this section to renew a certificate both with and without agent approval. To renew a certificate as a user without agent approval, use profiles that require the CMCUserSignedAuth authentication plug-in, and to renew with agent approval, use profiles that require the CMCAuth authentication plug-in. For further details about these plug-ins and in which profiles they are enabled by default, see Section 8.1.2, “CMC Authentication Plug-ins”.

5.4.1. Renewal Using the Same Key
Copy link

Section 5.3.1, “The CMC Enrollment Process” describes how to request and issue a certificate using CMC. When a user submits the same CMC request created during this process again with the same enrollment profile, Certificate System renews the certificate with the same key.

Note

For renewing a certificate as the user using the same key, the enrollment profile must contain the uniqueKeyConstraint entry with the params.allowSameKeyRenewal parameter set to True as described in Section 3.4.1, “About Renewal” and Section 3.4.1.1.1, “Renewing Using the Same Key”.

5.4.2. Renewal Using a New Key
Copy link

To renew a certificate using a new key, follow the procedure described in Section 5.3.1, “The CMC Enrollment Process”. The process for renewal is the same as for a new enrollment. When you sign the request with the same signing certificate, the newly issued certificate contains the same subjectDN attribute as the signing certificate.
This section details how a CA agent can trace an issued certificate to the original submitted CSR, and from a CSR to an issued certificate.
If a certificate request has been approved successfully, a CA agent can do the following to search for the request and see the CSR matching the certificate:
  1. Access the https://host_name:port/ca/agent/ca.
  2. Click Search for Requests
  3. Select and fill in Request ID Range (for example 12 for Lowest Request ID and 12 for Highest Request ID.
  4. Select Request Type and choose enrollment type.
  5. Select Request Status and choose completed status
  6. Make sure everything else is unselected.
  7. Click Submit.
  8. Click on the request number. You see the certificate in clear text at this point.
  9. To display the CSR and certificate linking, right-click and select This Frame and View Frame Source.
    • Search for inputList.inputName="Certificate Request";. The request is the inputList.inputVal below that.
    • Search for outputList.outputSyntax="pretty_print";. The certificate is the outputList.outputVal below that.
To search from certificate to CSR:
  1. Access the https://host_name:port/ca/agent/ca.
  2. Click Find.
  3. Click Details.
  4. You see the certificate in clear text, along with a Request ID link. Click on the link to open the Request page.
  5. To display the certificate and CSR linking:
    • Search for inputList.inputName="Certificate Request";. The request is the inputList.inputVal below that.
    • Search for outputList.outputSyntax="pretty_print";. The certificate is the outputList.outputVal below that.

Chapter 6. Revoking Certificates and Issuing CRLs
Copy link

The Certificate System provides methods for revoking certificates and for producing lists of revoked certificates, called certificate revocation lists (CRLs). This chapter describes the methods for revoking a certificate, describes CMC revocation, and provides details about CRLs and setting up CRLs.

6.1. About Revoking Certificates
Copy link

Certificates can be revoked by an end user (the original owner of the certificate) or by a Certificate Manager agent. An end user can revoke only certificates that contain the same subject name as the certificate presented for authentication.
When revocation requests are approved, the Certificate Manager marks the corresponding certificate records in its internal database as revoked, and, if configured to do so, removes the revoked certificates from the publishing directory. These changes are reflected in the next CRL which the CA issues.
Server and client applications that use public-key certificates as ID tokens need access to information about the validity of a certificate. Because one of the factors that determines the validity of a certificate is its revocation status, these applications need to know whether the certificate being validated has been revoked. The CA has a responsibility to do the following:
  • Revoke the certificate if a revocation request is received by the CA and approved.
  • Make the revoked certificate status available to parties or applications that need to verify its validity status.
Whenever a certificate is revoked, the Certificate Manager automatically updates the status of the certificate in its internal database, it marks the copy of the certificate in its internal database as revoked and removes the revoked certificate from the publishing directory, if the Certificate Manager is configured to remove the certificate from the database.
One of the standard methods for conveying the revocation status of certificates is by publishing a list of revoked certificates, known a certificate revocation list (CRL). A CRL is a publicly available list of certificates that have been revoked.
The Certificate Manager can be configured to generate CRLs. These CRLs can be created to conform to X.509 standards by enabling extension-specific modules in the CRL configuration. The server supports standard CRL extensions through its CRL issuing points framework; see Section 6.3.3, “Setting CRL Extensions” for more information on setting up CRL extensions for issuing points. The Certificate Manager can generate a CRL every time a certificate is revoked and at periodic intervals. If publishing is set up, the CRLs can be published to a file, an LDAP directory, or an OCSP responder.
A CRL is issued and digitally signed by the CA that issued the certificates listed in the CRL or by an entity that has been authorized by that CA to issue CRLs. The CA may use a single key pair to sign both the certificates and CRLs it issues or two separate key pairs, one for signing certificates and another one for signing CRLs.
By default, the Certificate Manager uses a single key pair for signing the certificates it issues and CRLs it generates. To create another key pair for the Certificate Manager and use it exclusively for signing CRLs, see 9.2.3.11. Setting a CA to Use a Different Certificate to Sign CRLs in Red Hat Certificate System's Planning, Installation, and Deployment Guide.
CRLs are generated when issuing points are defined and configured and when CRL generation is enabled.
When CRLs are enabled, the server collects revocation information as certificates are revoked. The server attempts to match the revoked certificate against all issuing points that are set up. A given certificate can match none of the issuing points, one of the issuing points, several of the issuing points, or all of the issuing points. When a certificate that has been revoked matches an issuing point, the server stores the information about the certificate in the cache for that issuing point.
The cache is copied to the internal directory at the intervals set for copying the cache. When the interval for creating a CRL is reached, a CRL is created from the cache. If a delta CRL has been set up for this issuing point, a delta CRL is also created at this time. The full CRL contains all revoked certificate information since the Certificate Manager began collecting this information. The delta CRL contains all revoked certificate information since the last update of the full CRL.
The full CRLs are numbered sequentially, as are delta CRLs. A full CRL and a delta CRL can have the same number; in that case, the delta CRL has the same number as the next full CRL. For example, if the full CRL is the first CRL, it is CRL 1. The delta CRL is Delta CRL 2. The data combined in CRL 1 and Delta CRL 2 is equivalent to the next full CRL, which is CRL 2.

Note

When changes are made to the extensions for an issuing point, no delta CRL is created with the next full CRL for that issuing point. A delta CRL is created with the second full CRL that is created, and then all subsequent full CRLs.
The internal database stores only the latest CRL and delta CRL. As each new CRL is created, the old one is overwritten.
When CRLs are published, each update to the CRL and delta CRL is published to the locations specified in the publishing set up. The method of publishing determines how many CRLs are stored. For file publishing, each CRL that is published to a file using the number for the CRL, so no file is overwritten. For LDAP publishing, each CRL that is published replaces the old CRL in the attribute containing the CRL in the directory entry.
By default, CRLs do not contain information about revoked expired certificates. The server can include revoked expired certificates by enabling that option for the issuing point. If expired certificates are included, information about revoked certificates is not removed from the CRL when the certificate expires. If expired certificates are not included, information about revoked certificates is removed from the CRL when the certificate expires.

6.1.1. CRL Issuing Points
Copy link

Because CRLs can grow very large, there are several methods to minimize the overhead of retrieving and delivering large CRLs. One of these methods partitions the entire certificate space and associates a separate CRL with every partition. This partition is called a CRL issuing point, the location where a subset of all the revoked certificates is maintained. Partitioning can be based on whether the revoked certificate is a CA certificate, whether it was revoked for a specific reason, or whether it was issued using a specific profile. Each issuing point is identified by its name.
By default, the Certificate Manager generates and publishes a single CRL, the master CRL. An issuing point can generate CRLs for all certificates, for only CA signing certificates, or for all certificates including expired certificates.
Once the issuing points have been defined, they can be included in certificates so that an application that needs to check the revocation status of a certificate can access the CRL issuing points specified in the certificate instead of the master or main CRL. Since the CRL maintained at the issuing point is smaller than the master CRL, checking the revocation status is much faster.
CRL distribution points can be associated with certificates by setting the CRLDistributionPoint extension.

6.1.2. Delta CRLs
Copy link

Delta CRLs can be issued for any defined issuing point. A delta CRL contains information about any certificates revoked since the last update to the full CRL. Delta CRLs for an issuing point are created by enabling the DeltaCRLIndicator extension.

6.1.3. Publishing CRLs
Copy link

The Certificate Manager can publish the CRL to a file, an LDAP-compliant directory, or to an OCSP responder. Where and how frequently CRLs are published are configured in the Certificate Manager, as described in Chapter 7, Publishing Certificates and CRLs.
Because CRLs can be very large, publishing CRLs can take a very long time, and it is possible for the process to be interrupted. Special publishers can be configured to publish CRLs to a file over HTTP1.1, and, if the process is interrupted, the CA subsystem's web server can resume publishing at the point it was interrupted, instead of having to begin again. This is described in Section 7.7, “Setting up Resumable CRL Downloads”.

6.2. Revoking Certificates
Copy link

6.2.1. Performing a CMC Revocation
Copy link

Similar to Certificate Management over CMS (CMC) enrollment, CMC revocation enables users to set up a revocation client, and sign the revocation request with either an agent certificate or a user certificate with a matching subjectDN attribute. Then the user can send the signed request to the Certificate Manager.
Alternatively, CMC revocation can also be authenticated using the Shared Secret Token mechanism. For details, see Section 8.1.3, “CMC SharedSecret Authentication”.
Regardless of whether a user or agent signs the request or if a Shared Secret Token is used, the Certificate Manager automatically revokes the certificate when it receives a valid revocation request.
Certificate System provides the following utilities for CMC revocation requests:

Important

Red Hat recommends using the CMCRequest utility to generate CMC revocation requests, because it provides more options than CMCRevoke.
6.2.1.1. Revoking a Certificate Using CMCRequest
Copy link
To revoke a certificate using CMCRequest:
  1. Create a configuration file for the CMC revocation request, such as /home/user_name/cmc-request.cfg, with the following content: 
    #numRequests: Total number of PKCS10 requests or CRMF requests.
numRequests=1

#output: full path for the CMC request in binary format
output=/home/user_name/cmc.revoke.userSigned.req

#tokenname: name of token where user signing cert can be found
#(default is internal)
tokenname=internal

#nickname: nickname for user signing certificate which will be used
#to sign the CMC full request.
nickname=signer_user_certificate

#dbdir: directory for cert8.db, key3.db and secmod.db
dbdir=/home/user_name/.dogtag/nssdb/

#password: password for cert8.db which stores the user signing
#certificate and keys
password=myPass

#format: request format, either pkcs10 or crmf.
format=pkcs10

## revocation parameters
revRequest.enable=true
revRequest.serial=45
revRequest.reason=unspecified
revRequest.comment=user test revocation
revRequest.issuer=issuer
revRequest.sharedSecret=shared_secret
    Copy to Clipboard Toggle word wrap
  2. Create the CMC request: 
    # CMCRequest /home/user_name/cmc-request.cfg
    Copy to Clipboard Toggle word wrap
    If the command succeeds, the CMCRequest utility stores the CMC request in the file specified in the output parameter in the request configuration file.
  3. Create a configuration file, such as /home/user_name/cmc-submit.cfg, which you use in a later step to submit the CMC revocation request to the CA. Add the following content to the created file: 
    #host: host name for the http server
host=>server.example.com

#port: port number
port=8443

#secure: true for secure connection, false for nonsecure connection
secure=true

#input: full path for the enrollment request, the content must be
#in binary format
input=/home/user_name/cmc.revoke.userSigned.req

#output: full path for the response in binary format
output=/home/user_name/cmc.revoke.userSigned.resp

#tokenname: name of token where TLS client authentication certificate
#can be found (default is internal)
#This parameter will be ignored if secure=false
tokenname=internal

#dbdir: directory for cert8.db, key3.db and secmod.db
#This parameter will be ignored if secure=false
dbdir=/home/user_name/.dogtag/nssdb/

#clientmode: true for client authentication, false for no client
#authentication. This parameter will be ignored if secure=false
clientmode=true

#password: password for cert8.db
#This parameter will be ignored if secure=false and clientauth=false
password=password

#nickname: nickname for client certificate
#This parameter will be ignored if clientmode=false
nickname=signer_user_certificate
    Copy to Clipboard Toggle word wrap

    Important

    If the CMC revocation request is signed, set the secure and clientmode parameters to true and, additionally, fill the nickname parameter.
  4. Depending on who signed the request, the servlet parameter in the configuration file for HttpClient must be set accordingly:
    • If an agent signed the request, set: 
      servlet=/ca/ee/ca/profileSubmitCMCFull
      Copy to Clipboard Toggle word wrap
    • If a user signed the request, set: 
      servlet=/ca/ee/ca/profileSubmitUserSignedCMCFull
      Copy to Clipboard Toggle word wrap
  5. Submit the CMC request: 
    # HttpClient /home/user_name/cmc-submit.cfg
    Copy to Clipboard Toggle word wrap
For further details about revoking a certificate using CMCRequest, see the CMCRequest(1) man page.
6.2.1.2. Revoking a Certificate Using CMCRevoke
Copy link
The CMC revocation utility, CMCRevoke, is used to sign a revocation request with an agent's certificate. This utility simply passes the required information — certificate serial number, issuer name, and revocation reason — to identify the certificate to revoke, and then the require information to identify the CA agent performing the revocation (certificate nickname and the database with the certificate).

Important

Using CMCRevoke requires that the CA administrator followed the instructions specified in the Enabling CMCRevoke for the Web User Interface section in the Red Hat Certificate System 9 Planning, Installation and Deployment Guide (Common Criteria Edition) during the installation.
The reason the certificate is being revoked can be any of the following (with the number being the value passed to the CMCRevoke utility):
  • 0 — unspecified
  • 1 — the key was compromised
  • 2 — the CA key was compromised
  • 3 — the employee's affiliation changed
  • 4 — the certificate has been superseded
  • 5 — cessation of operation
  • 6 — the certificate is on hold
The available tool arguments are described in detail in the Command-Line Tools Guide.
6.2.1.2.1. Testing CMCRevoke
Copy link
  1. Create a CMC revocation request for an existing certificate. 
    CMCRevoke -d/path/to/agent-cert-db -nnickname -iissuerName -sserialName -mreason -ccomment
    Copy to Clipboard Toggle word wrap
    For example, if the directory containing the agent certificate is ~jsmith/.mozilla/firefox/, the nickname of the certificate is AgentCert, and the serial number of the certificate is 22, the command is as shown: 
    CMCRevoke -d"~jsmith/.mozilla/firefox/" -n"ManagerAgentCert" -i"cn=agentAuthMgr" -s22 -m0 -c"test comment"
    Copy to Clipboard Toggle word wrap

    Note

    Surround values that include spaces in quotation marks.

    Important

    Do not have a space between the argument and its value. For example, giving a serial number of 26 is -s26, not -s 26.
  2. Open the end-entities page. 
    https://server.example.com:8443/ca/ee/ca
    Copy to Clipboard Toggle word wrap
  3. Select the Revocation tab.
  4. Select the CMC Revoke link on the menu.
  5. Paste the output from the CMCRevoke into the text area.
  6. Remove -----BEGIN NEW CERTIFICATE REQUEST----- and ----END NEW CERTIFICATE REQUEST----- from the pasted content.
  7. Click Submit.
  8. The returned page should confirm that correct certificate has been revoked.
A Certificate Manager agent can use the agent services page to find a specific certificate issued by the Certificate System or to retrieve a list of certificates that match specified criteria. The certificates which are retrieved can be examined or revoked by the agent. The Certificate Manager agent can also manage the certificate revocation list (CRL).
6.2.2.1. Listing Certificates
Copy link
It is possible to list certificates within a range of serial numbers. All certificates within the range may be displayed or, if the agent selects, only those that are currently valid.
To find a specific certificate or to list certificates by serial number:
  1. Open the Certificate Manager agent services page.
  2. Click List Certificates.
    List Certificates
    View larger image
    List Certificates

    Figure 6.1. List Certificates

    • To find a certificate with a specific serial number, enter the serial number in both the upper limit and lower limit fields of the List Certificates form, in either decimal or hexadecimal form. Use 0x to indicate the beginning of a hexadecimal number; for example, 0x00000006. Serial numbers are displayed in hexadecimal form in the Search Results and Details pages.
    • To find all certificates within a range of serial numbers, enter the upper and lower limits of the serial number range in decimal or hexadecimal form.
    Leaving either the lower limit or upper limit field blank displays the certificate with the specified number, plus all certificates before or after it in sequence.
  3. To limit the returned list to valid certificates, select the check boxes labeled with filtering methods. It is possible to include revoked certificates, to include expired certificates or certificates that are not yet valid, or to display only valid certificates.
  4. Enter the maximum number of certificates matching the criteria that should be returned in the results page.
    When any number is entered, the first certificates up to that number matching the criteria are displayed.
  5. Click Find.
    The Certificate System displays a list of the certificates that match the search criteria. Select a certificate in the list to examine it in more detail or perform various operations on it. For more information, refer to Section 6.2.2.3, “Examining Certificate Details”.
6.2.2.3. Examining Certificate Details
Copy link
  1. On the agent services page, click List Certificates or Search for Certificates, specify search criteria, and click Find to display a list of certificates.
  2. On the Search Results form, select a certificate to examine.
    If the desired certificate is not shown, scroll to the bottom of the list, specify an additional number of certificates to be returned, and click Find. The system displays the next certificates up to that number that match the original search criteria.
  3. After selecting a certificate, click the Details button at the left side of its entry.
  4. The Certificate page shows the detailed contents of the selected certificate and instructions for installing the certificate in a server or in a web browser.

  5. The certificate is shown in base-64 encoded form at the bottom of the Certificate page, under the heading Installing this certificate in a server.
6.2.2.4. Revoking Certificates
Copy link
Only Certificate Manager agents can revoke certificates other than their own. A certificate must be revoked if one of the following situations occurs:
  • The owner of the certificate has changed status and no longer has the right to use the certificate.
  • The private key of a certificate owner has been compromised.
These two reasons are not the only ones why a certificate would need revoked; there are six reasons available for revoking a certificate.
To revoke one or more certificates, search for the certificates to revoke using the Revoke Certificates button. While the search is similar to the one through the Search for Certificates form, the Search Results form returned by this search offers the option of revoking one or all of the returned certificates.
6.2.2.4.1. Revoking Certificates
Copy link
  1. Open the Certificate Manager agent services page.
  2. Click Revoke Certificates.

    Note

    The search form that appears has the same search criteria sections as the Search for Certificates form.
  3. Specify the search criteria by selecting the check boxes for the sections and filling in the required information.
  4. Scroll to the bottom of the form, and set the number of matching certificates to display.
  5. Click Find.
  6. The search returns a list of matching certificates. It is possible to revoke one or all certificates in the list.
    View larger image

    Note

    If the search criteria are very specific and all of the certificates returned are to be revoked, then click the Revoke ALL # Certificates button at the bottom of the page. The number shown on the button is the total number of certificates returned by the search. This is usually a larger number than the number of certificates displayed on the current page.
    Verify that all of the certificates returned by the search should be revoked, not only those displayed on the current page.
  7. Click the Revoke button next to the certificate to be revoked.

    Warning

    Whether revoking a single certificate or a list of certificates, be extremely careful that the correct certificate has been selected or that the list contains only certificates which should be revoked. Once a revocation operation has been confirmed, there is no way to undo it.
  8. Select an invalidity date. The invalidity date is the date which it is known or suspected that the user's private key was compromised or that the certificate became invalid. A set of drop down lists allows the agent to select the correct invalidity date.
    View larger image
  9. Select a reason for the revocation.
    • Key compromised
    • CA key compromised
    • Affiliation changed
    • Certificate superseded
    • Cessation of operation
    • Certificate is on hold
  10. Enter any additional comment. The comment is included in the revocation request.
When the revocation request is submitted, it is automatically approved, and the certificate is revoked. Revocation requests are viewed by listing requests with a status of Completed.
6.2.2.4.2. Taking Ceritificates Off Hold
Copy link
There can be instances when a certificate is inaccessible, and therefore should be treated as revoked, but that certificate can be recovered. For example, a user may have a personal email certificate stored on a flash drive which he accidentally leaves at home. The certificate is not compromised, but it should be temporarily suspended.
That certificate can be temporarily revoked by putting it on hold (one of the options given when revoking a certificate, as in Section 6.2.2.4.1, “Revoking Certificates”). At a later time — such as when the forgotten flash drive is picked up — that certificate can be taken off hold and is again active.
  1. Search for the on hold certificate, as in Section 6.2.2.2, “Searching for Certificates (Advanced)”. Scroll to the Revocation Information section, and set the Certificate is on hold revocation reason as the search criterion.
    View larger image
  2. In the results list, click the Off Hold button by the certificate to take off hold.
    View larger image
6.2.2.5. Managing the Certificate Revocation List
Copy link
Revoking a certificate notifies other users that the certificate is no longer valid. This notification is done by publishing a list of the revoked certificates, called the certificate revocation list (CRL), to an LDAP directory or to a flat file. This list is publicly available and ensures that revoked certificates are not misused.
6.2.2.5.1. Viewing or Examining CRLs
Copy link
It may be necessary to view or examine a CRL, such as before manually updating a directory with the latest CRL. To view or display the CRL:
  1. Go to the Certificate Manager agent services page.
  2. Click Display Certificate Revocation List to display the form for viewing the CRL.
  3. Select the CRL to view. If the administrator has created multiple issuing points, these are listed in the Issuing point drop-down list. Otherwise, only the master CRL is shown.
  4. Choose how to display the CRL by selecting one of the options from the Display Type menu. The choices on this menu are as follows:
    • Cached CRL. Views the CRL from the cache rather than from the CRL itself. This option displays results faster than viewing the entire CRL.
    • Entire CRL. Retrieves and displays the entire CRL.
    • CRL header. Retrieves and displays the CRL header only.
    • Base 64 Encoded. Retrieves and displays the CRL in base-64 encoded format.
    • Delta CRL. Retrieves and displays a delta CRL, which is a subset of the CRL showing only new revocations since the last CRL was published. This option is available only if delta CRL generation is enabled.
  5. To examine the selected CRL, click Display.
    The CRL appears in the browser window. This allows the agent to check whether a particular certificate (by its serial number) appears in the list and to note recent changes such as the total number of certificates revoked since the last update, the total number of certificates taken off hold since the last update, and the total number of certificates that expired since the last update.
6.2.2.5.2. Updating the CRL
Copy link
CRLs can be automatically updated if a schedule for automatic CRL generation is enabled, and the schedule can set the CRL to be generated at set time schedules or whenever there are certificate revocations.
Likewise, CRLs can be also automatically published if CRL publishing is enabled.
In some cases, the CRL may need to be updated manually, such as updating the list after the system has been down or removing expired certificates to reduce the file size. (Expired certificates do not need to be included in the CRL because they are already invalid because of the expiration date.) Only a Certificate Manager agent can manually update the CRL.
To update the CRL manually:
  1. Open the Certificate Manager agent services page.
  2. Click Update Revocation List to display the form for updating the CRL.
    Update Certificate Revocation List
    View larger image
    Update Certificate Revocation List

    Figure 6.3. Update Certificate Revocation List

  3. Select the CRL issuing point which will update the CRL. There can be multiple issuing points configured for a single CA.
  4. Select the algorithm to use to sign the new CRL. Before choosing an algorithm, make sure that any system or network applications that need to read or view this CRL support the algorithm.
    • SHA-256 with RSA.
    • SHA-384 with RSA.
    • SHA-512 with RSA.
    Before selecting an algorithm, make sure that the Certificate System has that algorithm enabled. The Certificate System administrator will have that information.
  5. Click Update to update the CRL with the latest certificate revocation information.
Revoking a certificate invalidates it before its expiration date. This can be necessary if a certificate is lost, compromised, or no longer needed.
6.2.3.1. Revoking Your User Certificate

  3. Select the radio button by Check whether the following certificate is included in CRL cache or Check whether the following certificate is listed by CRL, and enter the serial number of the certificate.
    View larger image
  4. Click the Submit button.
    A message is returned either saying that the certificate is not listed in any CRL or giving the information for the CRL which contains the certificate.
6.2.3.3. Downloading and Importing CRLs
Copy link
Certificate revocation lists (CRLs) can be downloaded and installed in a web client, application, or machine. They can also be viewed to see what certificates have been revoked.
  1. Click the Retrieval tab.
  2. Click the Import Certificate Revocation List link.
  3. Select the radio button to view, download, or import the CRL.
    View larger image
    • To import the CRL into the browser or download and save it, select the appropriate radio button. There are two options: to download/import the full CRL or the delta CRL. The delta CRL only imports/downloads the list of certificates which have been revoked since the last time the CRL was generated.
    • To view the CRL, select Display the CRL information and select which CRL subset (called an issuing point) to view. This shows the CRL information, including the number of certificates included in it.
      View larger image
  4. Click the Submit button.
  5. Save the file or approve the import operation.

6.3. Issuing CRLs
Copy link

  1. The Certificate Manager uses its OCSP signing key to sign CRLs. To use a separate signing key pair for CRLs, set up a CRL signing key and change the Certificate Manager configuration to use this key to sign CRLs. See 9.2.3.11. Setting a CA to Use a Different Certificate to Sign CRLs in Red Hat Certificate System's Planning, Installation, and Deployment Guide for more information.
  2. Set up CRL issuing points. An issuing point is already set up and enabled for a master CRL.
    Default CRL Issuing Point

    Default CRL Issuing Point

    Figure 6.4. Default CRL Issuing Point

    Additional issuing points for the CRLs can be created. See Section 6.3.1, “Configuring Issuing Points” for details.
    There are five types of CRLs the issuing points can create, depending on the options set when configuring the issuing point to define what the CRL will list:
    • Master CRL contains the list of revoked certificates from the entire CA.
    • ARL is an Authority Revocation List containing only revoked CA certificates.
    • CRL with expired certificates includes revoked certificates that have expired in the CRL.
    • CRL from certificate profiles determines the revoked certificates to include based on the profiles used to create the certificates originally.
    • CRLs by reason code determines the revoked certificates to include based on the revocation reason code.
  3. Configure the CRLs for each issuing point. See Section 6.3.2, “Configuring CRLs for Each Issuing Point” for details.
  4. Set up the CRL extensions which are configured for the issuing point. See Section 6.3.3, “Setting CRL Extensions” for details.
  5. Set up the delta CRL for an issuing point by enabling extensions for that issuing point, DeltaCRLIndicator or CRLNumber.
  6. Set up the CRLDistributionPoint extension to include information about the issuing point.
  7. Set up publishing CRLs to files, an LDAP directory, or an OCSP responder. See Chapter 7, Publishing Certificates and CRLs for details about setting up publishing.

6.3.1. Configuring Issuing Points
Copy link

Issuing points define which certificates are included in a new CRL. A master CRL issuing point is created by default for a master CRL containing a list of all revoked certificates for the Certificate Manager.
To create a new issuing point, do the following:
  1. Open the Certificate System Console. 
    pkiconsole https://server.example.com:8443/ca
    Copy to Clipboard Toggle word wrap
  2. In the Configuration tab, expand Certificate Manager from the left navigation menu. Then select CRL Issuing Points.
  3. To edit an issuing point, select the issuing point, and click Edit. The only parameters which can be edited are the name of the issuing point and whether the issuing point is enabled or disabled.
    To add an issuing point, click Add. The CRL Issuing Point Editor window opens.

    Figure 6.5. CRL Issuing Point Editor

    Note

    If some fields do not appear large enough to read the content, expand the window by dragging one of the corners.
    Fill in the following fields:
    • Enable. Enables the issuing point if selected; deselect to disable.
    • CRL Issuing Point name. Gives the name for the issuing point; spaces are not allowed.
    • Description. Describes the issuing point.
  4. Click OK.
To view and configure a new issuing point, close the CA Console, then open the Console again. The new issuing point is listed below the CRL Issuing Points entry in the navigation tree.
Configure CRLs for the new issuing point, and set up any CRL extensions that will be used with the CRL. See Section 6.3.2, “Configuring CRLs for Each Issuing Point” for details on configuring an issuing point. See Section 6.3.3, “Setting CRL Extensions” for details on setting up the CRL extensions. All the CRLs created appear on the Update Revocation List page of the agent services pages.

6.3.2. Configuring CRLs for Each Issuing Point
Copy link

Information, such as the generation interval, the CRL version, CRL extensions, and the signing algorithm, can all be configured for the CRLs for the issuing point. The CRLs must be configured for each issuing point.
  1. Open the CA console. 
    pkiconsole https://server.example.com:8443/ca
    Copy to Clipboard Toggle word wrap
  2. In the navigation tree, select Certificate Manager, and then select CRL Issuing Points.
  3. Select the issuing point name below the Issuing Points entry.
  4. Configure how and how often the CRLs are updated by supplying information in the Update tab for the issuing point. This tab has two sections, Update Schema and Update Frequency.
    • The Update Schema section has the following options:
      • Enable CRL generation. This checkbox sets whether CRLs are generated for that issuing point.
      • Generate full CRL every # delta(s). This field sets how frequently CRLs are created in relation to the number of changes.
      • Extend next update time in full CRLs. This provides an option to set the nextUpdate field in the generated CRLs. The nextUpdate parameter shows the date when the next CRL is issued, regardless of whether it is a full or delta CRL. When using a combination of full and delta CRLs, enabling Extend next update time in full CRLs will make the nextUpdate parameter in a full CRL show when the next full CRL will be issued. Otherwise, the nextUpdate parameter in the full CRL will show when the next delta CRL will be issued, since the delta will be the next CRL to be issued.
    • The Update Frequency section sets the different intervals when the CRLs are generated and issued to the directory.
      • Every time a certificate is revoked or released from hold. This sets the Certificate Manager to generate the CRL every time it revokes a certificate. The Certificate Manager attempts to issue the CRL to the configured directory whenever it is generated. Generating a CRL can be time consuming if the CRL is large. Configuring the Certificate Manager to generate CRLs every time a certificate is revoked may engage the server for a considerable amount of time; during this time, the server will not be able to update the directory with any changes it receives.
        This setting is not recommended for a standard installation. This option should be selected to test revocation immediately, such as testing whether the server issues the CRL to a flat file.
      • Update the CRL at. This field sets a daily time when the CRL should be updated. To specify multiple times, enter a comma-separate list of times, such as 01:50,04:55,06:55. To enter a schedule for multiple days, enter a comma-separated list to set the times within the same day, and then a semicolon separated list to identify times for different days. For example, this sets revocation on Day 1 of the cycle at 1:50am, 4:55am, and 6:55am and then Day 2 at 2am, 5am, and 5pm: 
        01:50,04:55,06:55;02:00,05:00,17:00
        Copy to Clipboard Toggle word wrap
      • Update the CRL every. This checkbox enables generating CRLs at the interval set in the field. For example, to issue CRLs every day, select the checkbox, and enter 1440 in this field.
      • Next update grace period. If the Certificate Manager updates the CRL at a specific frequency, the server can be configured to have a grace period to the next update time to allow time to create the CRL and issue it. For example, if the server is configured to update the CRL every 20 minutes with a grace period of 2 minutes, and if the CRL is updated at 16:00, the CRL is updated again at 16:18.

    Important

    Due to a known issue, when currently setting full and delta Certificate Revocation List schedules, the Update CRL every time a certificate is revoked or released from hold option also requires you to fill out the two grace period settings. Thus, in order to select this option you need to first select the Update CRL every option and enter a number for the Next update grace period # minutes box.
  5. The Cache tab sets whether caching is enabled and the cache frequency.

    • Enable CRL cache. This checkbox enables the cache, which is used to create delta CRLs. If the cache is disabled, delta CRLs will not be created. For more information about the cache, see Section 6.1, “About Revoking Certificates”.
    • Update cache every. This field sets how frequently the cache is written to the internal database. Set to 0 to have the cache written to the database every time a certificate is revoked.
    • Enable cache recovery. This checkbox allows the cache to be restored.
    • Enable CRL cache testing. This checkbox enables CRL performance testing for specific CRL issuing points. CRLs generated with this option should not be used in deployed CAs, as CRLs issued for testing purposed contain data generated solely for the purpose of performance testing.
  6. The Format tab sets the formatting and contents of the CRLs that are created. There are two sections, CRL Format and CRL Contents.
    CRL Format Tab

    • The CRL Format section has two options:
      • Revocation list signing algorithm is a drop down list of allowed ciphers to encrypt the CRL.
      • Allow extensions for CRL v2 is a checkbox which enabled CRL v2 extensions for the issuing point. If this is enabled, set the required CRL extensions described in Section 6.3.3, “Setting CRL Extensions”.

      Note

      Extensions must be turned on to create delta CRLs.
    • The CRL Contents section has three checkboxes which set what types of certificates to include in the CRL:
      • Include expired certificates. This includes revoked certificates that have expired. If this is enabled, information about revoked certificates remains in the CRL after the certificate expires. If this is not enabled, information about revoked certificates is removed when the certificate expires.
      • CA certificates only. This includes only CA certificates in the CRL. Selecting this option creates an Authority Revocation List (ARL), which lists only revoked CA certificates.
      • Certificates issued according to profiles. This only includes certificates that were issued according to the listed profiles; to specify multiple profiles, enter a comma-separated list.
  7. Click Save.
  8. Extensions are allowed for this issuing point and can be configured. See Section 6.3.3, “Setting CRL Extensions” for details.

6.3.3. Setting CRL Extensions

Note

Extensions only need configured for an issuing point if the Allow extensions for CRLs v2 checkbox is selected for that issuing point.
When the issuing point is created, three extensions are automatically enabled: CRLReason, InvalidityDate, and CRLNumber. Other extensions are available but are disabled by default. These can be enabled and modified. For more information about the available CRL extensions, see Section B.4.2, “Standard X.509 v3 CRL Extensions Reference”.

6.3.4. Generating CRLs from Cache
Copy link

By default, CRLs are generated from the CA's internal database. However, revocation information can be collected as the certificates are revoked and kept in memory. This revocation information can then be used to update CRLs from memory. Bypassing the database searches that are required to generate the CRL from the internal database significantly improves performance.

Note

Because of the performance enhancement from generating CRLs from cache, enable the enableCRLCache parameter in most environments. However, the Enable CRL cache testing parameter should not be enabled in a production environment.

6.4. Setting Full and Delta CRL Schedules
Copy link

CRLs are generated periodically. Setting that period is touched on in the configuration in Section 6.3.2, “Configuring CRLs for Each Issuing Point”.
CRLs are issued according to a time-based schedule. CRLs can be issued every single time a certificate is revoked, at a specific time of day, or once every so-many minutes.
Time-based CRL generation schedules apply to every CRL that is generated. There are two kinds of CRLs, full CRLs and delta CRLs. A full CRL has a record of every single revoked certificate, whereas delta CRLs contain only the certificates that have been revoked since the last CRL (delta or full) was generated.
By default, full CRLs are generated at every specified interval in the schedule. It is possible space out the time between generating full CRLs by generating interim delta CRLs. The generation interval is configured in the CRL schema, which sets the scheme for generating delta and full CRLs.
If the interval is set to 3, for example, then the first CRL generated will be both a full and delta CRL, then the next two generation updates are delta CRLs only, and then the fourth interval is both a full and delta CRL again. In other words, every third generation interval has both a full CRL and a delta CRL. 
Interval   1, 2, 3, 4, 5, 6, 7 ...
Full CRL   1        4        7 ...
Delta CRL  1, 2, 3, 4, 5, 6, 7 ...

Note

For delta CRLs to be generated in addition to full CRLs, the CRL cache must be enabled.
  1. Open the console.

  5. Set the update frequency, either by specifying the occasion of a certificate revocation, a cyclical interval or set times for the updates to occur:
    • Select the Update CRL every time a certificate is revoked or released from hold checkbox. The Update CRL every time a certificate is revoked or released from hold option also requires you to fill out the two Grace period settings. This is a known issue, and the bug is being tracked in Red Hat Bugzilla.
    • Select the Update CRL every time a certificate is revoked or released from hold checkbox.
    • Select the Update CRL at checkbox and enter specific times separated by commas, such as 01:50,04:55,06:55.
    • Select Update CRL every checkbox and enter the required interval, such as 240.
  6. Save the changes.

Important

The Update CRL every time a certificate is revoked or released from hold option also requires you to fill out the two grace period settings. This is a known issue, and the bug is being tracked in Red Hat Bugzilla.

Note

Schedule drift can occur when updating CRLs by interval. Typically, drift occurs as a result of manual updates and CA restarts.
To prevent schedule drift, select the Update CRL at checkbox and enter a value. The interval updates will resynchronize with the Update CRL at value every 24 hours.
Only one Update CRL at value will be accepted when updating CRLs by interval.
By default, CRL generaton schedules cover 24 hours. Also, by default, when full and delta CRLs are enabled full CRLs occur at specific intervals in place of one or all delta CRLs, i.e., every third update.
To set CRL generation schedules across multiple days, the list of times uses commas to separate times within the same day and a semicolon to delimit days: 
ca.crl.MasterCRL.dailyUpdates=01:00,03:00,18:00;02:00,05:00,17:00
Copy to Clipboard Toggle word wrap
This example updates CRLs on day one of the schedule at 01:00, 03:00, and 18:00, and on day two of the schedule at 02:00, 05:00, and 17:00. On day three the cycle starts again.

Note

The semicolon indicates a new day. Starting the list with a semicolon results in an initial day where no CRLs are generated. Likewise, ending the list with a semicolon adds a final day to the schedule where no CRLs are generated. Two semicolons together result in a day with no CRL generation.
To set full CRL updates independent of delta updates, the list of times accepts time values prepended with an asterisk to indicate when full CRL updates should occur: 
ca.crl.MasterCRL.dailyUpdates=01:00,03:00,18:00,*23:00;02:00,05:00,21:00,*23:30
Copy to Clipboard Toggle word wrap
This example generates delta CRL updates on day one at 01:00, 03:00, and 18:00, with a full and delta CRL update at 23:00. On day two, delta CRLs are updated at 02:00, 05:00, and 21:00, with a full and delta CRL update at 23:30. On day three, the cycle starts again.

Note

Both the semicolon and asterisk syntax works in the console.

6.5.1. Setting up the OCSP Responder
Copy link

If a CA within the security domain is selected when the Online Certificate Status Manager is configured, there is no extra step required to configure the OCSP service. The CA's CRL publishing is set up automatically, and its signing certificate is automatically added and trusted in the Online Certificate Status Manager's certificate database. However, if a non-security domain CA is selected, then the OCSP service must be manually configured after the Online Certificate Status Manager is configured.

Note

Not every CA within the security domain to which the OCSP Manager belongs is automatically trusted by the OCSP Manager when it is configured. Every CA in the certificate chain of the CA configured in the CA panel is trusted automatically by the OCSP Manager. Other CAs within the security domain but not in the certificate chain must be trusted manually.
To set up the Online Certificate Status Manager for a Certificate Manager outside the security domain:
  1. Configure the CRLs for every CA that will publish to an OCSP responder.
  2. Enable publishing, set up a publisher, and set publishing rules in every CA that the OCSP service will handle (Chapter 7, Publishing Certificates and CRLs). This is not necessary if the Certificate Managers publish to an LDAP directory and the Online Certificated Status Manager is set up to read from that directory.
  3. The certificate profiles must be configured to include the Authority Information Access extension, pointing to the location at which the Certificate Manager listens for OCSP service requests (Section 6.5.4, “Enabling the Certificate Manager's Internal OCSP Service”).
  4. Configure the OCSP Responder.
  5. Restart both subsystems after configuring them.
  6. Verify that the CA is properly connected to the OCSP responder (Section 6.5.2.1, “Verify Certificate Manager and Online Certificate Status Manager Connection”).

6.5.2. Identifying the CA to the OCSP Responder
Copy link

Before a CA is configured to publish CRLs to the Online Certificate Status Manager, the CA must be identified to the Online Certificate Status Manager by storing the CA signing certificate in the internal database of the Online Certificate Status Manager. The Certificate Manager signs CRLs with the key pair associated with this certificate; the Online Certificate Status Manager verifies the signature against the stored certificate.

Note

If a CA within the security domain is selected when the Online Certificate Status Manager is configured, there is no extra step required to configure the Online Certificate Status Manager to recognize the CA; the CA signing certificate is automatically added and trusted in the Online Certificate Status Manager's certificate database. However, if a non-security domain CA is selected, then the CA signing certificate must be manually added to the certificate database after the Online Certificate Status Manager is configured.
It is not necessary to import the certificate chain for a CA which will publish its CRL to the Online Certificate Status Manager. The only time a certificate chain is needed for the OCSP service is if the CA connects to the Online Certificate Status Manager through TLS authentication when it publishes its CRL. Otherwise, the Online Certificate Status Manager does not need to have the complete certificate chain.
However, the Online Certificate Status Manager must have the certificate which signed the CRL, either a CA signing certificate or a separate CRL signing certificate, in its certificate database. The OCSP service verifies the CRL by comparing the certificate which signed the CRL against the certificates in its database, not against a certificate chain. If both a root CA and one of its subordinate CAs publish CRLs to the Online Certificate Status Manager, the Online Certificate Status Manager needs the CA signing certificate of both CAs.
To import the CA or CRL signing certificate which is used to sign the certificates the CA is publishing to the Online Certificate Status Manager, do the following:
  1. Get the Certificate Manager's base-64 CA signing certificate from the end-entities page of the CA.
  2. Open the Online Certificate Status Manager agent page. The URL has the format https://hostname:SSLport/ocsp/agent/ocsp.
  3. In the left frame, click Add Certificate Authority.
  4. In the form, paste the encoded CA signing certificate inside the text area labeled Base 64 encoded certificate (including the header and footer).
  5. To verify that the certificate is added successfully, in the left frame, click List Certificate Authorities.
The resulting form should show information about the new CA. The This Update, Next Update, and Requests Served Since Startup fields should show a value of zero (0).
When the Certificate Manager is restarted, it tries to connect to the Online Certificate Status Manager's TLS port. To verify that the Certificate Manager did indeed communicate with the Online Certificate Status Manager, check the This Update and Next Update fields, which should be updated with the appropriate timestamps of the CA's last communication with the Online Certificate Status Manager. The Requests Served Since Startup field should still show a value of zero (0) since no client has tried to query the OCSP service for certificate revocation status.
The Online Certificate Status Manager stores each Certificate Manager's CRL in its internal database and uses it as the CRL store for verifying the revocation status of certificates. To change the configuration that the Online Certificate Status Manager uses for storing the CRLs in its internal database:
  1. Open the Online Certificate Status Manager Console. 
    pkiconsole https://server.example.com:8443/ocsp

    • notFoundAsGood. Sets the OCSP service to return an OCSP response of GOOD if the certificate in question cannot be found in any of the CRLs. If this is not selected, the response is UNKNOWN, which, when encountered by a client, results in an error message.
    • byName. The OCSP Responder only supports the basic response type, which includes the ID of the OCSP Responder making the response. The ResponderID field within the basic response type is determined by the value of the ocsp.store.defStore.byName parameter. If byName parameter is true or is missing, the OCSP authority signing certificate subject name is used as the ResponderID field of the OCSP response. If byName parameter is false, the OCSP authority signing certificate key hash will be the ResponderID field of the OCSP response.
    • includeNextUpdate. Includes the timestamp of the next CRL update time.
Although the OCSP Manager stores the CA CRLs in its internal database by default, it can be configured to use a CRL published to an LDAP directory instead.

Important

If the ldapStore method is enabled, the OCSP user interface does not check the certificate status.
To configure the Online Certificate Status Manager to use an LDAP directory:
  1. Open the Online Certificate Status Manager Console.

    • port. The non-TLS port of the LDAP directory.
    • baseDN. The DN to start searching for the CRL. For example, O=example.com.
    • refreshInSec. How often the connection is refreshed. The default is 86400 seconds (daily).
    • caCertAttr. Leave the default value, cACertificate;binary, as it is. It is the attribute to which the Certificate Manager publishes its CA signing certificate.
    • crlAttr. Leave the default value, certificateRevocationList;binary, as it is. It is the attribute to which the Certificate Manager publishes CRLs.
    • notFoundAsGood. Sets the OCSP service to return an OCSP response of GOOD if the certificate in question cannot be found in any of the CRLs. If this is not selected, the response is UNKNOWN, which, when encountered by a client, results in an error message.
    • byName. The OCSP Responder only supports the basic response type, which includes the ID of the OCSP Responder making the response. The ResponderID field within the basic response type is determined by the value of the ocsp.store.defStore.byName parameter.

If byName parameter is false, the OCSP authority signing certificate key hash will be the ResponderID field of the OCSP response.
    • includeNextUpdate. The Online Certificate Status Manager can include the timestamp of the next CRL update time.
6.5.2.4. Testing the OCSP Service Setup
Copy link
Test whether the Certificate Manager can service OCSP requests properly by doing the following:
  1. Turn on revocation checking in the browser or client.
  2. Request a certificate from the CA that has been enabled for OCSP services.
  3. Approve the request.
  4. Download the certificate to the browser or client.
  5. Make sure the CA is trusted by the browser or client.
  6. Check the status of Certificate Manager's internal OCSP service.
    Open the CA agent services page, and select the OCSP Services link.
  7. Test the independent Online Certificate Status Manager subsystem.
    Open the Online Certificate Status Manager agent services page, and click the List Certificate Authorities link.
    The page should show information about the Certificate Manager configured to publish CRLs to the Online Certificate Status Manager. The page also summarizes the Online Certificate Status Manager's activity since it was last started.
  8. Revoke the certificate.
  9. Verify the certificate in the browser or client. The server should return that the certificate has been revoked.
  10. Check the Certificate Manager's OCSP-service status again to verify that these things happened:
    • The browser sent an OCSP query to the Certificate Manager.
    • The Certificate Manager sent an OCSP response to the browser.
    • The browser used that response to validate the certificate and returned its status, that the certificate could not be verified.
  11. Check the independent OCSP service subsystem again to verify that these things happened:
    • The Certificate Manager published the CRL to the Online Certificate Status Manager.
    • The browser sent an OCSP response to the Online Certificate Status Manager.
    • The Online Certificate Status Manager sent an OCSP response to the browser.
    • The browser used that response to validate the certificate and returned its status, that the certificate could not be verified.

6.5.3. Setting the Response for Bad Serial Numbers
Copy link

OCSP responders check the revocation status and expiration date of a certificate before determining whether the certificate is valid; by default, the OCSP does not validate other information on the certificate.
The notFoundAsGood parameter sets how the OCSP handles a certificate with an invalid serial number. This parameter is enabled by default, which means that if a certificate is present with a bad serial number but the certificate is otherwise valid, the OCSP returns a status of GOOD for the certificate.
To have the OCSP check and reject certificates based on bad serial numbers as well as revocation status, change the notFoundAsGood setting. In that case, the OCSP returns a status of UNKNOWN with a certificate with a bad serial number. The client interprets that as an error and can respond accordingly.
  1. Open the Online Certificate Status Manager Console. 
    pkiconsole https://server.example.com:8443/ocsp

  3. Select the defStore, and click Edit/View.
  4. Edit the notFoundAsGood value. Selecting the checkbox means that the OCSP returns a value of GOOD even if the serial number on the certificate is bad. Unselecting the checkbox means that the OCSP sends a value of UNKNOWN, which the client can intrepret as an error.
    View larger image
  5. Restart the OCSP Manager. 
    systemctl restart pki-tomcatd-nuxwdog@instance_name.service
    Copy to Clipboard Toggle word wrap
The Certificate Manager has a built-in OCSP service, which can be used by OCSP-compliant clients to query the Certificate Manager directly about the revocation status of the certificate. When the Certificate Manager is installed, an OCSP signing certificate is issued and the OCSP service is turned on by default. This OCSP signing certificate is used to sign all responses to OCSP service requests. Since the internal OCSP service checks the status of certificates stored in the Certificate Manager's internal database, publishing does not have to be configured to use this service.
Clients can query the OCSP service through the non-TLS end-entity port of the Certificate Manager. When queried for the revocation status of a certificate, the Certificate Manager searches its internal database for the certificate, checks its status, and responds to the client. Since the Certificate Manager has real-time status of all certificates it has issued, this method of revocation checking is the most accurate.
Every CA's built-in OCSP service is turned on at installation. However, to use this service, the CA needs to issue certificates with the Authority Information Access extension.
  1. Go to the CA's end-entities page. For example: 
    https://server.example.com:8443/ca/ee/ca
    Copy to Clipboard Toggle word wrap
  2. Find the CA signing certificate.
  3. Look for the Authority Info Access extension in the certificate, and note the Location URIName value, such as https://server.example.com:8443/ca/ocsp.
  4. Update the enrollment profiles to enable the Authority Information Access extension, and set the Location parameter to the Certificate Manager's URI. For information on editing the certificate profiles, see Section 3.2, “Setting up Certificate Profiles”.
  5. Restart the CA instance. 
    systemctl restart pki-tomcatd-nuxwdog@instance_name.service

--help Show help message
OCSP requests which are smaller than 255 bytes can be submitted to the Online Certificate Status Manager using a GET method, as described in RFC 6960. To submit OCSP requests over GET:
  1. Generate an OCSP request for the certificate the status of which is being queried. For example: 
    ]# openssl ocsp -CAfile ca.pem -issuer issuer.pem -serial serial_number -reqout - | base64 

MEIwQDA+MDwwOjAJBgUrDgMCGgUABBT4cyABkyiCIhU4JpmIBewdDnn8ZgQUbyBZ44kgy35o7xW5BMzM8FTvyTwCAQE=

  2. Paste the URL in the address bar of a web browser to return the status information. The browser must be able to handle OCSP requests. 
    https://server.example.com:8443/ocsp/ee/ocsp/MEIwQDA+MDwwOjAJBgUrDgMCGgUABBT4cyABkyiCIhU4JpmIBewdDnn8ZgQUbyBZ44kgy35o7xW5BMzM8FTvyTwCAQE=

  3. The OCSP Manager responds with the certificate status which the browser can interpret. The possible statuses are GOOD, REVOKED, and UNKNOWN.
Alternatively, run the OCSP from the command line by using a tool such as curl to send the request and openssl to parse the response. For example:
  1. Generate an OCSP request for the certificate the status of which is being queried. For example: 
    ]# openssl ocsp -CAfile ca.pem -issuer issuer.pem -serial serial_number -reqout - | base64

Chapter 7. Publishing Certificates and CRLs
Copy link

Note

Features in this section on TMS are not tested in the evaluation. This section is for reference only.
Red Hat Certificate System includes a customizable publishing framework for the Certificate Manager, enabling certificate authorities to publish certificates, certificate revocation lists (CRLs), and other certificate-related objects to any of the supported repositories: an LDAP-compliant directory, a flat file, and an online validation authority. This chapter explains how to configure a Certificate Manager to publish certificates and CRLs to a file, to a directory, and to the Online Certificate Status Manager.
The general process to configure publishing is as follows:
  1. Configure publishing to a file, LDAP directory, or OCSP responder.
    There can be a single publisher or multiple publishers, depending on how many locations will be used. The locations can be split by certificates and CRLs or narrower definitions, such as certificate type. Rules determine which type to publish and to what location by being associated with the publisher.
  2. Set rules to determine what certificates are published to the locations. Any rule which a certificate or CRL matches is activated, so the same certificate can be published to a file and to an LDAP directory by matching a file-based rule and matching a directory-based rule.
    Rules can be set for each object type: CA certificates, CRLs, user certificates, and cross-pair certificates. Disable all rules that will not be used.
  3. Configure CRLs. CRLs must be configured before they can be published. See Chapter 6, Revoking Certificates and Issuing CRLs.
  4. Enable publishing after setting up publishers, mappers, and rules. Once publishing is enabled, the server starts publishing immediately. If the publishers, mappers, and rules are not completely configured, publishing may not work correctly or at all.

7.1. About Publishing
Copy link

The Certificate System is capable of publishing certificates to a file or an LDAP directory and of publishing CRLs to a file, an LDAP directory, or to an OCSP responder.
For additional flexibility, specific types of certificates or CRLs can be published to a single format or all three. For example, CA certificates can be published only to a directory and not to a file, and user certificates can be published to both a file and a directory.

Note

An OCSP responder only provides information about CRLs; certificates are not published to an OCSP responder.
Different publishing locations can be set for certificates files and CRL files, as well as different publishing locations for different types of certificates files or different types of CRL files.
Similarly, different types of certificates and different types of CRLs can be published to different places in a directory. For example, certificates for users from the West Coast division of a company can be published in one branch of the directory, while certificates for users in the East Coast division can be published to another branch in the directory.
When publishing is enabled, every time a certificate or a CRL is issued, updated, or revoked, the publishing system is invoked. The certificate or CRL is evaluated by the rules to see if it matches the type and predicate set in the rule. The type specifies if the object is a CRL, CA certificate, or any other certificate. The predicate sets more criteria for the type of object being evaluated. For example, it can specify user certificates, or it can specify West Coast user certificates. To use predicates, a value needs to be entered in the predicate field of the publishing rule, and a corresponding value (although formatted somewhat differently) needs to be contained in the certificate or certificate request to match. The value in the certificate or certificate request may be derived from information in the certificate, such as the type of certificate, or may be derived from a hidden value that is placed in the request form. If no predicate is set, all certificates of that type are considered to match. For example, all CRLs match the rule if CRL is set as the type.
Every rule that is matched publishes the certificate or CRL according to the method and location specified in that rule. A given certificate or CRL can match no rules, one rule, more than one rule, or all rules. The publishing system attempts to match every certificate and CRL issued against all rules.
When a rule is matched, the certificate or CRL is published according to the method and location specified in the publisher associated with that rule. For example, if a rule matches all certificates issued to users, and the rule has a publisher that publishes to a file in the location /etc/CS/certificates, the certificate is published as a file to that location. If another rule matches all certificates issued to users, and the rule has a publisher that publishes to the LDAP attribute userCertificate;binary attribute, the certificate is published to the directory specified when LDAP publishing was enabled in this attribute in the user's entry.
For rules that specify to publish to a file, a new file is created when either a certificate or a CRL is issued in the stipulated directory.
For rules that specify to publish to an LDAP directory, the certificate or CRL is published to the entry specified in the directory, in the attribute specified. The CA overwrites the values for any published certificate or CRL attribute with any subsequent certificate or CRL. Simply put, any existing certificate or CRL that is already published is replaced by the next certificate or CRL.
For rules that specify to publish to an Online Certificate Status Manager, a CRL is published to this manager. Certificates are not published to an Online Certificate Status Manager.
For LDAP publishing, the location of the user's entry needs to be determined. Mappers are used to determine the entry to which to publish. The mappers can contain an exact DN for the entry, some variable that associates information that can be gotten from the certificate to create the DN, or enough information to search the directory for a unique attribute or set of attributes in the entry to ascertain the correct DN for the entry.
When a certificate is revoked, the server uses the publishing rules to locate and delete the corresponding certificate from the LDAP directory or from the filesystem.
When a certificate expires, the server can remove that certificate from the configured directory. The server does not do this automatically; the server must be configured to run the appropriate job.
Setting up publishing involves configuring publishers, mappers, and rules.

7.1.1. Publishers
Copy link

Publishers specify the location to which certificates and CRLs are published. When publishing to a file, publishers specify the filesystem publishing directory. When publishing to an LDAP directory, publishers specify the attribute in the directory that stores the certificate or CRL; a mapper is used to determine the DN of the entry. For every DN, a different formula is set for deriving that DN. The location of the LDAP directory is specified when LDAP publishing is enabled. When publishing a CRL to an OCSP responder, publishers specify the hostname and URI of the Online Certificate Status Manager.

7.1.2. Mappers
Copy link

Mappers are only used in LDAP publishing. Mappers construct the DN for an entry based on information from the certificate or the certificate request. The server has information from the subject name of the certificate and the certificate request and needs to know how to use this information to create a DN for that entry. The mapper provides a formula for converting the information available either to a DN or to some unique information that can be searched in the directory to obtain a DN for the entry.

7.1.3. Rules
Copy link

Rules for file, LDAP, and OCSP publishing tell the server whether and how a certificate or CRL is to be published. A rule first defines what is to be published, a certificate or CRL matching certain characteristics, by setting a type and predicate for the rule. A rule then specifies the publishing method and location by being associated with a publisher and, for LDAP publishing, with a mapper.
Rules can be as simple or complex as necessary for the PKI deployment and are flexible enough to accommodate different scenarios.

7.1.4. Publishing to Files
Copy link

The server can publish certificates and CRLs to flat files, which can then be imported into any repository, such as a relational database. When the server is configured to publish certificates and CRLs to file, the published files are DER-encoded binary blobs, base-64 encoded text blobs, or both.
  • For each certificate the server issues, it creates a file that contains the certificate in either DER-encoded or base-64 encoded format. Each file is named either cert-serial_number.der or cert-serial_number.b64. The serial_number is the serial number of the certificate contained in the file. For example, the filename for a DER-encoded certificate with the serial number 1234 is cert-1234.der.
  • Every time the server generates a CRL, it creates a file that contains the new CRL in either DER-encoded or base-64 encoded format. Each file is named either issuing_point_name-this_update.der or issuing_point_name-this_update.b64, depending on the format. The issuing_point_name identifies the CRL issuing point which published the CRL, and this_update specifies the value derived from the time-dependent update value for the CRL contained in the file. For example, the filename for a DER-encoded CRL with the value This Update: Friday January 28 15:36:00 PST 2021, is MasterCRL-20210128-153600.der.

7.1.5. OCSP Publishing
Copy link

There are two forms of Certificate System OCSP services, an internal service for the Certificate Manager and the Online Certificate Status Manager. The internal service checks the internal database of the Certificate Manager to report on the status of a certificate. The internal service is not set for publishing; it uses the certificates stored in its internal database to determine the status of a certificate. The Online Certificate Status Manager checks CRLs sent to it by Certificate Manager. A publisher is set for each location a CRL is sent and one rule for each type of CRL sent.
For detailed information on both OCSP services, see Section 6.5, “Using the Online Certificate Status Protocol (OCSP) Responder”.

7.1.6. LDAP Publishing
Copy link

In LDAP publishing, the server publishes the certificates, CRLs, and other certificate-related objects to a directory using LDAP or LDAPS. The branch of the directory to which it publishes is called the publishing directory.
  • For each certificate the server issues, it creates a blob that contains the certificate in its DER-encoded format in the specified attribute of the user's entry. The certificate is published as a DER encoded binary blob.
  • Every time the server generates a CRL, it creates a blob that contains the new CRL in its DER-encoded format in the specified attribute of the entry for the CA.
The server can publish certificates and CRLs to an LDAP-compliant directory using the LDAP protocol or LDAP over TLS (LDAPS) protocol, and applications can retrieve the certificates and CRLs over HTTP. Support for retrieving certificates and CRLs over HTTP enables some browsers to import the latest CRL automatically from the directory that receives regular updates from the server. The browser can then use the CRL to check all certificates automatically to ensure that they have not been revoked.
For LDAP publishing to work, the user entry must be present in the LDAP directory.
If the server and publishing directory become out of sync for some reason, privileged users (administrators and agents) can also manually initiate the publishing process. For instructions, see Section 7.11.2, “Manually Updating the CRL in the Directory”.

7.2. Configuring Publishing to a File
Copy link

The general process to configure publishing involves setting up a publisher to publish the certificates or CRLs to the specific location. There can be a single publisher or multiple publishers, depending on how many locations will be used. The locations can be split by certificates and CRLs or finer definitions, such as certificate type. Rules determine which type to publish and to what location by being associated with the publisher.
Publishing to file simply publishes the CRLs or certificates to text files on a given host.
Publishers must be created and configured for each publishing location; publishers are not automatically created for publishing to a file. To publish all files to a single location, create one publisher. To publish to different locations, create a publisher for each location. A location can either contain an object type, like user certificates, or a subset of an object type, like West Coast user certificates.
To create publishers for publishing to files:
  1. Log into the Certificate Manager Console. 
    pkiconsole https://server.example.com:8443/ca
    Copy to Clipboard Toggle word wrap
  2. In the Configuration tab, select Certificate Manager from the navigation tree on the left. Select Publishing, and then Publishers.
    The Publishers Management tab, which lists configured publisher instances, opens on the right.

  3. Click Add to open the Select Publisher Plug-in Implementation window, which lists registered publisher modules.
    View larger image
  4. Select the FileBasedPublisher module, then open the editor window.
    This is the module that enables the Certificate Manager to publish certificates and CRLs to files.
    View larger image
  5. Configure the information for publishing the certificate:
    • The publisher ID, an alphanumeric string with no spaces like PublishCertsToFile
    • The path to the directory in which the Certificate Manager should publish the files. The path can be an absolute path or can be relative to the Certificate System instance directory. For example, /export/CS/certificates.
    • The file type to publish, by selecting the checkboxes for DER-encoded files, base-64 encoded files, or both.
    • For CRLs, the format of the timestamp. Published certificates include serial numbers in their file names, while CRLs use timestamps.
    • For CRLs, whether to generate a link in the file to go to the latest CRL. If enabled, the link assumes that the name of the CRL issuing point to use with the extension will be supplied in the crlLinkExt field.
    • For CRLs, whether to compress (zip) CRLs and the compression level to use.
After configuring the publisher, configure the rules for the published certificates and CRLs, as described in Section 7.5, “Creating Rules”.

7.3. Configuring Publishing to an OCSP
Copy link

The general process to configure publishing involves setting up a publisher to publish the certificates or CRLs to the specific location. There can be a single publisher or multiple publishers, depending on how many locations will be used. The locations can be split by certificates and CRLs or finer definitions, such as certificate type. Rules determine which type to publish and to what location by being associated with the publisher.
Publishing to an OCSP Manager is a way to publish CRLs to a specific location for client verification.
A publisher must be created and configured for each publishing location; publishers are not automatically created for publishing to the OCSP responder. Create a single publisher to publish everything to s single location, or create a publisher for every location to which CRLs will be published. Each location can contain a different kind of CRL.
  1. Log into the Certificate Manager Console. 
    pkiconsole https://server.example.com:8443/ca
    Copy to Clipboard Toggle word wrap
  2. In the Configuration tab, select Certificate Manager from the navigation tree on the left. Select Publishing, and then Publishers.

  3. Click Add to open the Select Publisher Plug-in Implementation window, which lists registered publisher modules.
    View larger image
  4. Select the OCSPPublisher module, then open the editor window. This is the publisher module that enables the Certificate Manager to publish CRLs to the Online Certificate Status Manager.
    View larger image
    • The publisher ID must be an alphanumeric string with no spaces, like PublishCertsToOCSP.
    • The host can be the fully-qualified domain name, such as ocspResponder.example.com, or an IPv4 or IPv6 address.
    • The default path is the directory to send the CRL to, like /ocsp/agent/ocsp/addCRL.
    • If client authentication is used (enableClientAuth is checked), then the nickname field gives the nickname of the certificate to use for authentication. This certificate must already exist in the OCSP security database; this will usually be the CA subsystem certificate.
  5. Create a user entry for the CA on the OCSP Manager. The user is used to authenticate to the OCSP when sending a new CRL. There are two things required:
    • Name the OCSP user entry after the CA server, like CA-hostname-EEport.
    • Use whatever certificate was specified in the publisher configuration as the user certificate in the OCSP user account. This is usually the CA's subsystem certificate.
    Setting up subsystem users is covered in Section 12.3.2.1, “Creating Users”.
After configuring the publisher, configure the rules for the published certificates and CRLs, as described in Section 7.5, “Creating Rules”.

7.4. Configuring Publishing to an LDAP Directory
Copy link

The general process to configure publishing involves setting up a publisher to publish the certificates or CRLs to the specific location. There can be a single publisher or multiple publishers, depending on how many locations will be used. The locations can be split by certificates and CRLs or finer definitions, such as certificate type. Rules determine which type to publish and to what location by being associated with the publisher.
Configuring LDAP publishing is similar to other publishing procedures, with additional steps to configure the directory:
  1. Configure the Directory Server to which certificates will be published. Certain attributes have to be added to entries and bind identities and authentication methods have to be configured.
  2. Configure a publisher for each type of object published: CA certificates, cross-pair certificates, CRLs, and user certificates. The publisher declares in which attribute to store the object. The attributes set by default are the X.500 standard attributes for storing each object type. This attribute can be changed in the publisher, but generally, it is not necessary to change the LDAP publishers.
  3. Set up mappers to enable an entry's DN to be derived from the certificate's subject name. This generally does not need set for CA certificates, CRLs, and user certificates. There can be more than one mapper set for a type of certificate. This can be useful, for example, to publish certificates for two sets of users from different divisions of a company who are located in different parts of the directory tree. A mapper is created for each of the groups to specify a different branch of the tree.
    For details about setting up mappers, see Section 7.4.3, “Creating Mappers”.
  4. Create rules to connect publishers to mappers, as described in Section 7.5, “Creating Rules”.
  5. Enable publishing, as described in Section 7.6, “Enabling Publishing”.

7.4.1. Configuring the LDAP Directory
Copy link

Before certificates and CRLs can be published, the Directory Server must be configured to work with the publishing system. This means that user entries must have attributes that allow them to receive certificate information, and entries must be created to represent the CRLs.
  1. Set up the entry for the CA. For the Certificate Manager to publish its CA certificate and CRL, the directory must include an entry for the CA.

    Note

    When LDAP publishing is configured, the Certificate Manager automatically creates or converts an entry for the CA in the directory. This option is set in both the CA and CRL mapper instances and enabled by default. If the directory restricts the Certificate Manager from creating entries in the directory, turn off this option in those mapper instances, and add an entry for the CA manually in the directory.
    View larger image
    When adding the CA's entry to the directory, select the entry type based on the DN of the CA:
    • If the CA's DN begins with the cn component, create a new person entry for the CA. Selecting a different type of entry may not allow the cn component to be specified.
    • If the CA's DN begins with the ou component, create a new organizationalunit entry for the CA.
    The entry does not have to be in the pkiCA or certificationAuthority object class. The Certificate Manager will convert this entry to the pkiCA or certificationAuthority object class automatically by publishing its CA's signing certificate.

    Note

    The pkiCA object class is defined in RFC 4523, while the certificationAuthority object class is defined in the (obsolete) RFC 2256. Either object class is acceptable, depending on the schema definitions used by the Directory Server. In some situations, both object classes can be used for the same CA entry.
    For more information on creating directory entries, see the Red Hat Directory Server documentation.
  2. Add the correct schema elements to the CA and user directory entries.
    For a Certificate Manager to publish certificates and CRLs to a directory, it must be configured with specific attributes and object classes.
    Expand
    Object Type Schema Reason
    End-entity certificate userCertificate;binary (attribute)
    This is the attribute to which the Certificate Manager publishes the certificate.
    This is a multi-valued attribute, and each value is a DER-encoded binary X.509 certificate. The LDAP object class named inetOrgPerson allows this attribute. The strongAuthenticationUser object class allows this attribute and can be combined with any other object class to allow certificates to be published to directory entries with other object classes. The Certificate Manager does not automatically add this object class to the schema table of the corresponding Directory Server.
    If the directory object that it finds does not allow the userCertificate;binary attribute, adding or removing the certificate fails.
    CA certificate caCertificate;binary (attribute)
    This is the attribute to which the Certificate Manager publishes the certificate.
    The Certificate Manager publishes its own CA certificate to its own LDAP directory entry when the server starts. The entry corresponds to the Certificate Manager's issuer name.
    This is a required attribute of the pkiCA or certificationAuthority object class. The Certificate Manager adds this object class to the directory entry for the CA if it can find the CA's directory entry.
    CRL certificateRevocationList;binary (attribute)
    This is the attribute to which the Certificate Manager publishes the CRL.
    The Certificate Manager publishes the CRL to its own LDAP directory entry. The entry corresponds to the Certificate Manager's issuer name.
    This is an attribute of the pkiCA or certificationAuthority object class. The value of the attribute is the DER-encoded binary X.509 CRL. The CA's entry must already contain the pkiCA or certificationAuthority object class for the CRL to be published to the entry.
    Delta CRL deltaRevocationList;binary (attribute)
    This is the attribute to which the Certificate Manager publishes the delta CRL. The Certificate Manager publishes the delta CRL to its own LDAP directory entry, separate from the full CRL. The delta CRL entry corresponds to the Certificate Manager's issuer name.
    This attribute belongs to the deltaCRL or certificationAuthority-V2 object class. The value of the attribute is the DER-encoded binary X.509 delta CRL.
  3. Set up a bind DN for the Certificate Manager to use to access the Directory Server.
    The Certificate Manager user must have read-write permissions to the directory to publish certificates and CRLs to the directory so that the Certificate Manager can modify the user entries with certificate-related information and the CA entry with CA's certificate and CRL related information.
    The bind DN entry can be either of the following:
    • An existing DN that has write access, such as the Directory Manager.
    • A new user which is granted write access. The entry can be identified by the Certificate Manager's DN, such as cn=testCA, ou=Research Dept, o=Example Corporation, st=California, c=US.

      Note

      Carefully consider what privileges are given to this user. This user can be restricted in what it can write to the directory by creating ACLs for the account. For instructions on giving write access to the Certificate Manager's entry, see the Directory Server documentation.
  4. Set the directory authentication method for how the Certificate Manager authenticates to Directory Server. There are three options: basic authentication (simple username and password); TLS without client authentication (simple username and password); and TLS with client authentication (certificate-based).
    See the Red Hat Directory Server documentation for instructions on setting up these methods of communication with the server.

7.4.2. Configuring LDAP Publishers
Copy link

The Certificate Manager creates, configures, and enables a set of publishers that are associated with LDAP publishing. The default publishers (for CA certificates, user certificates, CRLs, and cross-pair certificates) already conform to the X.500 standard attributes for storing certificates and CRLs and do not need to be changed.
Expand
Table 7.1. LDAP Publishers
Publisher Description
LdapCaCertPublisher Publishes CA certificates to the LDAP directory.
LdapCrlPublisher Publishes CRLs to the LDAP directory.
LdapDeltaCrlPublisher Publishes delta CRLs to the LDAP directory.
LdapUserCertPublisher Publishes all types of end-entity certificates to the LDAP directory.
LdapCrossCertPairPublisher Publishes cross-signed certificates to the LDAP directory.

7.4.3. Creating Mappers
Copy link

Mappers are only used with LDAP publishing. Mappers define a relationship between a certificate's subject name and the DN of the directory entry to which the certificate is published. The Certificate Manager needs to derive the DN of the entry from the certificate or the certificate request so it can determine which entry to use. The mapper defines the relationship between the DN for the user entry and the subject name of the certificate or other input information so that the exact DN of the entry can be determined and found in the directory.
When it is configured, the Certificate Manager automatically creates a set of mappers defining the most common relationships. The default mappers are listed in Table 7.2, “Default Mappers”.
Expand
Table 7.2. Default Mappers
Mapper Description
LdapUserCertMap Locates the correct attribute of user entries in the directory in order to publish user certificates.
LdapCrlMap Locates the correct attribute of the CA's entry in the directory in order to publish the CRL.

To use the default mappers, configure each of the macros by specifying the DN pattern and whether to create the CA entry in the directory. To use other mappers, create and configure an instance of the mapper. For more information, see Section C.2, “Mapper Plug-in Modules ”.

After configuring the mappers for LDAP publishing, configure the rules for the published certificates and CRLs, as described in Section 7.5, “Creating Rules”.
Once the configuration is complete, enable publishing, as described in Section 7.6, “Enabling Publishing”.

7.5. Creating Rules
Copy link

Rules determine what certificate object is published in what location. Rules work independently, not in tandem. A certificate or CRL that is being published is matched against every rule. Any rule which it matches is activated. In this way, the same certificate or CRL can be published to a file, to an Online Certificate Status Manager, and to an LDAP directory by matching a file-based rule, an OCSP rule, and matching a directory-based rule.
Rules can be set for each object type: CA certificates, CRLs, user certificates, and cross-pair certificates. The rules can be more detailed for different kinds of certificates or different kinds of CRLs.
The rule first determines if the object matches by matching the type and predicate set up in the rule with the object. Where matching objects are published is determined by the publisher and mapper associated with the rule.
Rules are created for each type of certificate the Certificate Manager issues.
Modify publishing rules by doing the following:
  1. Log into the Certificate Manager Console. 
    pkiconsole https://server.example.com:8443/ca

7.6. Enabling Publishing
Copy link

Publishing can be enabled for only files, only LDAP, or both. Publishing should be enabled after setting up publishers, rules, and mappers. Once enabled, the server attempts to begin publishing. If publishing was not configured correctly before being enabled, publishing may exhibit undesirable behavior or may fail.

Note

Configure CRLs. CRLs must be configured before they can be published. See Chapter 6, Revoking Certificates and Issuing CRLs.

    In the Destination section, set the information for the Directory Server instance.
    • Host name. If the Directory Server is configured for TLS client authenticated communication, the name must match the cn component in the subject DN of the Directory Server's TLS server certificate.
      The hostname can be the fully-qualified domain name or an IPv4 or IPv6 address.
    • Port number.
    • Directory Manager DN. This is the distinguished name (DN) of the directory entry that has Directory Manager privileges. The Certificate Manager uses this DN to access the directory tree and to publish to the directory. The access control set up for this DN determines whether the Certificate Manager can perform publishing. It is possible to create another DN that has limited read-write permissions for only those attributes that the publishing system actually needs to write.
    • Password. This is the password which the CA uses to bind to the LDAP directory to which the certificate or CRL is published. The Certificate Manager saves this password in its password.conf file. For example: 
      CA LDAP Publishing:password
      Copy to Clipboard Toggle word wrap
    • Client certificate. This sets the certificate the Certificate Manager uses for TLS client authentication to the publishing directory. By default, the Certificate Manager uses its TLS server certificate.
    • LDAP version. Select LDAP version 3.
    • Authentication. The way the Certificate Manager authenticates to the Directory Server. The choices are Basic authentication and TLS client authentication.
      If the Directory Server is configured for basic authentication or for TLS communication without client authentication, select Basic authentication and specify values for the Directory manager DN and password.
      If the Directory Server is configured for TLS communication with client authentication, select TLS client authentication and the Use TLS communication option, and identify the certificate that the Certificate Manager must use for TLS client authentication to the directory.
The server attempts to connect to the Directory Server. If the information is incorrect, the server displays an error message.

7.7. Setting up Resumable CRL Downloads
Copy link

Certificate System provides option for interrupted CRL downloads to be resumed smoothly. This is done by publishing the CRLs as a plain file over HTTP. This method of downloading CRLs gives flexibility in retrieving CRLs and lowers overall network congestion.

7.7.1. Retrieving CRLs Using wget
Copy link

Because CRLs can be published as a text file over HTTP, they can be manually retrieved from the CA using a tool such as wget. The wget command can be used to retrieve any published CRL. For example, to retrieve a full CRL which is newer than the previous full CRL: 
[root@server ~]# wget --no-check-certificate -d https://server.example.com:8443/ca/ee/ca/crl/MasterCRL.bin

-N Retrieves the CRL that is newer than the local copy (delta CRL).
-c Retrieves a partially-downloaded file.
--no-check-certificate Skips TLS for the connection, so it is not necessary to configure TLS between the host and client.
-d Prints debug information.

7.8. Publishing Cross-Pair Certificates

The cross-pair certificates can be published as a crossCertificatePair entry to an LDAP directory or to a file; this is enabled by default. If this has been disabled, it can be re-enabled through the Certificate Manager Console by doing the following:
  1. Open the CA console. 
    pkiconsole https://server.example.com:8443/ca
    Copy to Clipboard Toggle word wrap
  2. In the Configuration tab, select the Certificate Manager link in the left pane, then the Publishing link.
  3. Click the Rules link under Publishing. This opens the Rules Management pane on the right.
  4. If the rule exists and has been disabled, select the enable checkbox. If the rule has been deleted, then click Add and create a new rule.
    1. Select xcerts from the type drop-down menu.
    2. Make sure the enable checkbox is selected.
    3. Select LdapCaCertMap from the mapper drop-down menu.
    4. Select LdapCrossCertPairPublisher from the publisher drop-down menu.
The mapper and publisher specified in the publishing rule are both listed under Mapper and Publisher under the Publishing link in the left navigation window of the CA Console. The mapper, LdapCaCertMap, by default designates that the crossCertificatePair be stored to the LdapCaSimpleMap LDAP entry. The publisher, LDAPCrossPairPublisher, by default sets the attribute to store the cross-pair certificate in the CA entry to crossCertificatePair;binary.

7.9. Testing Publishing to Files
Copy link

To verify that the Certificate Manager is publishing certificates and CRLs correctly to file:
  1. Open the CA's end-entities page, and request a certificate.
  2. Approve the request through the agent services page, if required.
  3. Retrieve the certificate from the end-entities page, and download the certificate into the browser.
  4. Check whether the server generated the DER-encoded file containing the certificate.
    Open the directory to which the binary blob of the certificate is supposed to be published. The certificate file should be named cert-serial_number.der.
  5. Convert the DER-encoded certificate to its base 64-encoded format using the Binary to ASCII tool. For more information on this tool, refer to the BtoA(1) man page. 
    BtoA input_file output_file
    Copy to Clipboard Toggle word wrap
    input_file sets the path to the file that contains the DER-encoded certificate, and output_file sets the path to the file to write the base-64 encoded certificate.
  6. Open the ASCII file; the base-64 encoded certificate is similar to the one shown: 
    -----BEGIN CERTIFICATE-----
MMIIBtgYJYIZIAYb4QgIFoIIBpzCCAZ8wggGbMIIBRaADAgEAAgEBMA0GCSqGSIb3DQEBBAUAMFcxC
AJBgNVBAYTAlVTMSwwKgYDVQQKEyNOZXRzY2FwZSBDb21tdW5pY2F0aWhfyyuougjgjjgmkgjkgmjg

GlvbjpMEaMBgGA1UECxMRSXNzdWluZyBBdXRob3JpdHkwHh
-----END CERTIFICATE-----
    Copy to Clipboard Toggle word wrap
  7. Convert the base 64-encoded certificate to a readable form using the Pretty Print Certificate tool. For more information on this tool, refer to the PrettyPrintCert(1) man page. 
    PrettyPrintCert input_file [output_file]
    Copy to Clipboard Toggle word wrap
    input_file sets the path to the ASCII file that contains the base-64 encoded certificate, and output_file, optionally, sets the path to the file to write the certificate. If an output file is not set, the certificate information is written to the standard output.
  8. Compare the output with the certificate issued; check the serial number in the certificate with the one used in the filename.
    If everything matches, the Certificate Manager is configured correctly to publish certificates to file.
  9. Revoke the certificate.
  10. Check whether the server generated the DER-encoded file containing the CRL.
    Open the directory to which the server is to publish the CRL as a binary blob. The CRL file should have a name in the form crl-this_update.der. this_update specifies the value derived from the time-dependent This Update variable of the CRL.
  11. Convert the DER-encoded CRL to its base 64-encoded format using the Binary to ASCII tool. 
    BtoA input_file output_file
    Copy to Clipboard Toggle word wrap
  12. Convert the base 64-encoded CRL to readable form using the Pretty Print CRL tool. 
    PrettyPrintCrl input_file [output_file]
    Copy to Clipboard Toggle word wrap
  13. Compare the output.
Certificates and CRLs can be published to two types of files: base-64 encoded or DER-encoded. The content of these files can be viewed by converting the files to pretty-print format using the dumpasn1 tool or the PrettyPrintCert or PrettyPrintCrl tool.
To view the content in a base-64 encoded file:
  1. Convert the base-64 file to binary. For example: 
    AtoB /tmp/example.b64 /tmp/example.bin
    Copy to Clipboard Toggle word wrap
  2. Use the PrettyPrintCert or PrettyPrintCrl tool to convert the binary file to pretty-print format. For example: 
    PrettyPrintCert example.bin example.cert
    Copy to Clipboard Toggle word wrap
To view the content of a DER-encoded file, simply run the dumpasn1, PrettyPrintCert, or PrettyPrintCrl tool with the DER-encoded file. For example: 
PrettyPrintCrl example.der example.crl
Copy to Clipboard Toggle word wrap
The Certificate Manager and the publishing directory can become out of sync if certificates are issued or revoked while the Directory Server is down. Certificates that were issued or revoked need to be published or unpublished manually when the Directory Server comes back up.
To find certificates that are out of sync with the directory ‐ valid certificates that are not in the directory and revoked or expired certificates that are still in the directory ‐ the Certificate Manager keeps a record of whether a certificate in its internal database has been published to the directory. If the Certificate Manager and the publishing directory become out of sync, use the Update Directory option in the Certificate Manager agent services page to synchronize the publishing directory with the internal database.
The following choices are available for synchronizing the directory with the internal database:
  • Search the internal database for certificates that are out of sync and publish or unpublish.
  • Publish certificates that were issued while the Directory Server was down. Similarly, unpublish certificates that were revoked or that expired while Directory Server was down.
  • Publish or unpublish a range of certificates based on serial numbers, from serial number xx to serial number yy.
A Certificate Manager's publishing directory can be manually updated by a Certificate Manager agent only.
The Update Directory Server form in the Certificate Manager agent services page can be used to update the directory manually with certificate-related information. This form initiates a combination of the following operations:
  • Update the directory with certificates.
  • Remove expired certificates from the directory.
    Removing expired certificates from the publishing directory can be automated by scheduling an automated job.
  • Remove revoked certificates from the directory.
Manually update the directory with changes by doing the following:
  1. Open the Certificate Manager agent services page.
  2. Select the Update Directory Server link.
  3. Select the appropriate options, and click Update Directory.
    The Certificate Manager starts updating the directory with the certificate information in its internal database. If the changes are substantial, updating the directory can take considerable time. During this period, any changes made through the Certificate Manager, including any certificates issued or any certificates revoked, may not be included in the update. If any certificates are issued or revoked while the directory is updated, update the directory again to reflect those changes.
When the directory update is complete, the Certificate Manager displays a status report. If the process is interrupted, the server logs an error message.
If the Certificate Manager is installed as a root CA, the CA signing certificate may get published using the publishing rule set up for user certificates when using the agent interface to update the directory with valid certificates. This may return an object class violation error or other errors in the mapper. Selecting the appropriate serial number range to exclude the CA signing certificate can avoid this problem. The CA signing certificate is the first certificate a root CA issues.
  • Modify the default publishing rule for user certificates by changing the value of the predicate parameter to profileId!=caCACert.
  • Use the LdapCaCertPublisher publisher plug-in module to add another rule, with the predicate parameter set to profileId=caCACert, for publishing subordinate CA certificates.

7.11.2. Manually Updating the CRL in the Directory
Copy link

The Certificate Revocation List form in the Certificate Manager agent services page manually updates the directory with CRL-related information.
Manually update the CRL information by doing the following:
  1. Open the Certificate Manager agent services page.
  2. Select Update Revocation List.
  3. Click Update.
The Certificate Manager starts updating the directory with the CRL in its internal database. If the CRL is large, updating the directory takes considerable time. During this period, any changes made to the CRL may not be included in the update.
When the directory is updated, the Certificate Manager displays a status report. If the process is interrupted, the server logs an error message.
The auth.instance_id parameter in a profile specifies the authentication mechanism. A certificate request can either be automatically approved through an authentication plug-in, or be manually approved by a CA agent.

Note

For instructions on how to edit certificate enrollment profiles, see Section 3.2, “Setting up Certificate Profiles”.
Configuring that enrollment requests are automatically approved depends on the type of requests:
  • For agent-pre-approved CMC requests, set in the CA profile: 
    auth.instance_id=CMCAuth
authz.acl=group="Certificate Manager Agents"
    Copy to Clipboard Toggle word wrap
    The authz.acl parameter defines the group that is allowed to approve requests.
  • For user-initiated requests:
    • When using CMC Shared Token, set in the CA profile: 
      auth.instance_id=CMCUserSignedAuth
      Copy to Clipboard Toggle word wrap
      Required default and constraint: 
      policyset.cmcUserCertSet.1.constraint.class_id=cmcSharedTokenSubjectNameConstraintImpl
policyset.cmcUserCertSet.1.constraint.name=CMC Shared Token Subject Name Constraint
policyset.cmcUserCertSet.1.default.class_id=authTokenSubjectNameDefaultImpl
policyset.cmcUserCertSet.1.default.name=Subject Name Default
      Copy to Clipboard Toggle word wrap
    • When using User-signed requests, set in the CA profile: 
      auth.instance_id=CMCUserSignedAuth
      Copy to Clipboard Toggle word wrap
      Required default and constraint: 
      policyset.cmcUserCertSet.1.default.params.name=
policyset.cmcUserCertSet.9.constraint.class_id=uniqueKeyConstraintImpl
policyset.cmcUserCertSet.9.constraint.name=Unique Key Constraint
policyset.cmcUserCertSet.9.constraint.params.allowSameKeyRenewal=true
policyset.cmcUserCertSet.9.default.class_id=noDefaultImpl
policyset.cmcUserCertSet.9.default.name=No Default

For details about editing a profile, see Section 3.2, “Setting up Certificate Profiles”.

8.1.2. CMC Authentication Plug-ins
Copy link

Certificate System provides the following authentication plug-ins:
CMCAuth
Use this plug-in when a CA agent signs CMC requests.
To use the CMCAuth plug-in, set the following in the enrollment profile: 
auth.instance_id=CMCAuth
Copy to Clipboard Toggle word wrap
By default, the following enrollment profiles use the CMCAuth plug-in:
  • For system certificates:
    • caCMCauditSigningCert
    • caCMCcaCert
    • caCMCECserverCert
    • caCMCECsubsystemCert
    • caCMCECUserCert
    • caCMCkraStorageCert
    • caCMCkraTransportCert
    • caCMCocspCert
    • caCMCserverCert
    • caCMCsubsystemCert
  • For user certificates:
    • caCMCUserCert
    • caECFullCMCUserCert
    • caFullCMCUserCert
CMCUserSignedAuth
Use this plug-in when users submit signed or SharedSecret-based CMC requests.
To use the CMCUserSignedAuth plug-in, set the following in the enrollment profile: 
auth.instance_id=CMCUserSignedAuth
Copy to Clipboard Toggle word wrap
A user-signed CMC request must be signed by the user's certificate which contains the same subjectDN attribute as the requested certificate. You can only use a user-signed CMC request if the user already obtained a signing certificate which can be used to prove the user's identity for other certificates.
A SharedSecret-based CMC request means that the request was signed by the private key of the request itself. In this case, the CMC request must use the Shared Secret mechanism for authentication. A SharedSecret-based CMC request is typically used to obtain the user's first signing certificate, which is later used to obtain other certificates. For further details, see Section 8.1.3, “CMC SharedSecret Authentication”.
By default, the following enrollment profiles use the CMCUserSignedAuth plug-in:
  • caFullCMCUserSignedCert
  • caECFullCMCUserSignedCert
  • caFullCMCSharedTokenCert
  • caECFullCMCSharedTokenCert

8.1.3. CMC SharedSecret Authentication
Copy link

Use the Shared Secret feature to enable users to send unsigned CMC requests to the server. For example, this is necessary if a user wants to obtain the first signing certificate. This signing certificate can later be used to sign other certificates of this user.
8.1.3.1. Creating a Shared Secret Token
Copy link
The The Shared Secret Workflow section in the Red Hat Certificate System Planning, Installation, and Deployment Guide (Common Criteria Edition) describes the workflow when using a Shared Secret Token. Depending on the situation, either an end entity user or an administrator creates the Shared Secret Token.

Note

To use the shared secret token, Certificate System must use an RSA issuance protection certificate. For details, see Enabling the CMC Shared Secret Feature section located in RHCS Planning, Installation, and Deployment Guide.
To create a Shared Secret Token, enter: 
# CMCSharedToken -d /home/user_name/.dogtag/ -p NSS_password \
     -s "CMC_enrollment_password" -o /home/user_name/CMC_shared_token.b64 \
     -n "issuance_protection_certificate_nickname"
Copy to Clipboard Toggle word wrap
If you use an HSM, additionally pass the -h token_name option to the command to set the HSM security token name.
For further details about the CMCSharedToken utility, see the CMCSharedToken(8) man page.

Note

The generated token is encrypted and only the user who generated knows the password. If a CA administrator generates the token for a user, the administrator must provide the password to the user using a secure way.
After creating the Shared Token, an administrator must add the token to a user or certificate record. For details, see Section 8.1.3.2, “Setting a CMC Shared Secret”.
8.1.3.2. Setting a CMC Shared Secret
Copy link
Depending on the planned action, an administrator must store a Shared Secret Token after generating it in the LDAP entry of the user or certificate.
For details about the workflow and when to use a Shared Secret, see the The Shared Secret Workflow section in the Red Hat Certificate System Planning, Installation, and Deployment Guide (Common Criteria Edition).
To use the Shared Secret Token for certificate enrollment, store it as an administrator in the LDAP entry of the user: 
# ldapmodify -D "cn=Directory Manager" -W -p 389 -h server.example.com -x

dn: uid=user_name,ou=People,dc=example,dc=com
changetype: modify
replace: shrTok
shrTok: base64-encoded_token
Copy to Clipboard Toggle word wrap
To use the Shared Secret Token for certificate revocations, store it as an administrator in the LDAP entry of the certificate to be revoked: 
 # ldapmodify -D "cn=Directory Manager" -W -p 389 -h server.example.com -x

dn: cn=certificate_id,ou=certificateRepository,ou=ca,o=pki-tomcat-CA
changetype: modify
replace: shrTok
shrTok: base64-encoded_token
Copy to Clipboard Toggle word wrap

8.2. Manual Approval by a CA Agent
Copy link

If manual approval is configured in a CA profile, users can create CMC requests, but requests must be manually approved by a CA agent.
To configure manual agent approval in a CA profile:
  1. Set the auth.instance_id to an empty value: 
    auth.instance_id=
    Copy to Clipboard Toggle word wrap
  2. Do not set the authz.acl parameter.
For details about editing a profile, see Section 3.2, “Setting up Certificate Profiles”.
To review certificate requests, ensure that you are authenticated as an agent with proper permissions to approve certificate requests. For details about configuring the pki command-line interface, see Section 2.5.1.1, “pki CLI Initialization”.
To review the requests:
  1. Display the list of pending certificate requests: 
    $ pki agent_authentication_parameters ca-cert-request-find --status pending
    Copy to Clipboard Toggle word wrap
    This command lists all pending certificate requests.
  2. Download a particular certificate request: 
    $ pki agent_authentication_parameters ca-cert-request-review id --file request.xml
    Copy to Clipboard Toggle word wrap
  3. Open the request.xml file in an editor or a separate terminal, and review the contents of the request to ensure it is legitimate. Then answer the prompt: if the request is valid, answer "approve and press Enter. If the request is invalid, answer reject and press Enter. Organizations can subscribe semantic differences to reject and cancel; both result in no certificate being issued.
  1. Open the following URL in a web browser: 
    https://server_host_name:8443/ca/agent/ca
    Copy to Clipboard Toggle word wrap
  2. Authenticate as an agent. For information about authenticating as a user and configuring your browser, see Section 2.4.1, “Browser Initialization”.
  3. On the sidebar on the left, click the List requests link.
  4. Filter the requests be selecting Show all requests for Request type and Show pending requests for Request status.
  5. Click Find in the lower right corner.
    View larger image
  6. The results page lists all pending requests waiting for review. Click on the request number to review a request.
  7. Review the request information and ensure that it is a legitimate request. If necessary, modify the policy information to correct any mistakes or make any desired changes to the certificate, such as changing the not valid after field. Optionally, leave an additional note.
    View larger image
    The drop down menu includes several review status updates. Select Approve request to approve the request or Reject request to deny it, and click Submit. Organizations can subscribe semantic differences to Reject request and Cancel Request; both result in no certificate being issued.
This chapter describes the authorization mechanism using access evaluators.

Note

For instructions on how to edit certificate enrollment profiles, see Section 3.2, “Setting up Certificate Profiles”.

9.1. Authorization Mechanism
Copy link

In addition to the authentication mechanism, each enrollment profile can be configured to have its own authorization mechanism. The authorization mechanism is executed only after a successful authentication.
The authorization mechanism is provided by the Access Evaluator plug-in framework. Access evaluators are pluggable classes that are used for evaluating access control instructions (ACI) entries. The mechanism provides an evaluate method that takes a predefined list of arguments (that is, type, op, value), evaluates an expression such as group='Certificate Manager Agents' and returns a boolean depending on the result of evaluation.

9.2. Default Evaluators
Copy link

Red Hat Certificate System provides four default evaluators. 
accessEvaluator.impl.group.class=com.netscape.cms.evaluators.GroupAccessEvaluator
accessEvaluator.impl.ipaddress.class=com.netscape.cms.evaluators.IPAddressAccessEvaluator
accessEvaluator.impl.user.class=com.netscape.cms.evaluators.UserAccessEvaluator
accessEvaluator.impl.user_origreq.class=com.netscape.cms.evaluators.UserOrigReqAccessEvaluator
Copy to Clipboard Toggle word wrap
The group access evaluator evaluates the group membership properties of a user. For example, in the following enrollment profile entry, only the CA agents are allowed to go through enrollment with that profile: 
authz.acl=group="Certificate Manager Agents"
Copy to Clipboard Toggle word wrap
The ipaddress access evaluator evaluates the IP address of the requesting subject. For example, in the following enrollment profile entry, only the host bearing the specified IP address can go through enrollment with that profile: 
authz.acl=ipaddress="a.b.c.d.e.f"
Copy to Clipboard Toggle word wrap
The user access evaluator evaluates the user ID for exact match. For example, in the following enrollment profile entry, only the user matching the listed user is allowed to go through enrollment with that profile: 
authz.acl=user="bob"
Copy to Clipboard Toggle word wrap
The user_origreq access evaluator evaluates the authenticated user against a previous matching request for equality. This special evaluator is designed specifically for renewal purpose to make sure the user requesting the renewal is the same user that owns the original request. For example, in the following renewal enrollment profile entry, the UID of the authenticated user must match the UID of the user requesting the renewal: 
authz.acl=user_origreq="auth_token.uid"
Copy to Clipboard Toggle word wrap
New evaluators can be written in the current framework and can be registered through the CS console. The default evaluators can be used as templates to expand and customize into more targeted plug-ins.

Chapter 10. Self Tests
Copy link

10.1. Running Self-Tests
Copy link

The Certificate System has the added functionality to allow self-tests of the server. The self-tests are run at start up and can also be run on demand. The startup self-tests run when the server starts and keep the server from starting if a critical self-test fails. The on-demand self-tests are run by clicking the self-tests button in the subsystem console.

10.1.1. Running Self-Tests
Copy link

The on-demand self-test for the CA, OCSP, KRA, or TKS subsystems are run from the console. The on-demand self-tests for the TPS system are run from the web services page.
10.1.1.1. Running Self-Tests from the Console
Copy link
  1. Log into the Console. 
    pkiconsole https://server.example.com:admin_port/subsystem_type
    Copy to Clipboard Toggle word wrap
  2. Select the subsystem name at the top of the left pane.
    View larger image
  3. Select the Self Tests tab.
  4. Click Run.
    The self-tests that are configured for the subsystem will run. If any critical self-tests fail, the server will stop.
  5. The On-Demand Self Tests Results window appears, showing the logged events for this run of the self-tests.
10.1.1.2. Running TPS Self-Tests
Copy link
To run TPS self-tests from the command-line interface (CLI):
  • pki tps-selftest-find
  • pki tps-selftest-run
  • pki tps-selftest-show

10.2. Debugging Self-Tests Failures
Copy link

In the event of self-test failure, the Certificate System instance will stop completely and will not respond to any HTTP or HTTPS requests.
To diagnose a manually run self-test failure, refer to the various logs described in Section 10.2.1, “Self-Test Logging”. Often other logs are useful as well, including debug logs. For more information on subsystem logs, refer to Chapter 13, Configuring Subsystem Logs. For more information on debug logs, refer to the Logs section under the Certificate System Architecture Overview in the Red Hat Certificate System Planning, Installation, and Deployment Guide (Common Criteria Edition).
Common causes of self-test failures are services (such as LDAP) are down or unreachable, certificates are expired, or the system configuration is wrong. A precise cause of self-test failure is given in the logs.
After the cause of the self-test failure is identified and fixed, please restart the Certificate System server to resume normal operations: 
# systemctl restart pki-tomcatd-nuxwdog@instance_name.service

About Crypto Tokens
For information about NSS soft token, please see 2.3.8.1. NSS Soft Token (internal token) in Red Hat Certificate System's Planning, Installation, and Deployment Guide.

11.1. About certutil and PKICertImport
Copy link

The certutil command is provided by Network Security Services (NSS). certutil is used for validating and importing certificates. A basic overview of how we use certutil is presented below, however, PKICertImport is our wrapper script of choice for safely validating and importing certificates. Using certutil to do so requires multiple command invocations and correct usage is outside the scope of this documentation.

11.1.1. certutil Basic Usage
Copy link

certutil [command] [options]
Each certutil invocation takes a command flag, usually denoted by a capital letter, and a series of options which control what the command does. If an option takes a value, that value is named between "<" and ">" symbols.

11.1.2. PKICertImport Basic Usage
Copy link

PKICertImport [options]
Each PKICertImport invocation accepts a series of options to validate and import a specified certificate. Unlike the broad use cases of certutil, PKICertImport is only focused on safely importing and validating certificates. See Section 11.1.4, “Common certutil and PKICertImport Options” for more information about available options.

Note

PKICertImport prompts for the NSS DB and/or HSM passwords multiple times throughout the course of its execution. This is expected as PKICertImport has to interact with the NSS DB multiple times. To avoid having to input the NSS DB password repetitively, specify a password file via -f <filename>. When done, be sure to delete the password file.

11.1.3. certutil Common Commands
Copy link

The following commands are specific to certutil and provide a brief overview of several common commands. PKICertImport is not compatible with nor require these command flags.
certutil -A
The -A command denotes "adding" a certificate. It requires a certificate to import (-i), a nickname (-n) for that certificate, and a series of trust flags (-t) for the certificate.
certutil -V
The -V command denotes "verifying" a certificate. It requires a certificate nickname to validate (-n) and a type of verification (-u) to perform.
certutil -D
The -D command denotes "deleting" a certificate. It requires a certificate nickname (-n) to remove.
Note that it ONLY removes the PUBLIC KEY portion of the certificate, and WILL NOT remove any private keys, if present.
certutil -M
The -M command denotes "modifying" a certificate. It requires a certificate nickname (-n) to modify, and a series of trust flags (-t) to give the certificate.
certutil -L
The -L command denotes "listing" a certificate or all certificates. If given the nickname option (-n), it will list detailed information about that certificate, else if omitted, it will list general information about all certificates present.
The result of certutil -L would show each certificate by its nickname along with its trust info. For example:
Expand
Table 11.1. Certificate nickname and trust info
Certificate Nickname

Trust Attributes
SSL, S/MIME, JAR/XPI

caSigningCert pki-ca1
CT, C, C

Note

The trust attributes displayed by certutil -L correspond to what is specified with the -t option.
The certutil -L does not modify the database, and can thus be executed safely as many times as desired.

11.1.4. Common certutil and PKICertImport Options
Copy link

When following the steps below, ensure the values are relevant and correct for your specific deployment scenario. Many of these options are available to PKICertImport as well.
-n <nickname>
The -n <nickname> option specifies the nickname for a certificate. This can be any text and is only used as a reference to the certificate. It MUST be unique.
Update this value as appropriate for your configuration.
-d <directory>
The -d <directory> option specifies the path to the NSS DB directory in use. We usually assume you are already in this directory and use "." to refer to the current directory.
Update this value as appropriate for your configuration.
-t <trust>
The -t <trust> option specifies the trust level for the certificate.
There are three main categories of trust:
  • trust for TLS
  • trust for email
  • trust for object signing
Each trust position can have one or more trust letters which specify the desired level of trust. The trust letters we use below are c, C, and T.
  • c states that this certificate should be a Certificate Authority (CA).
  • C states that this is a trusted certificate authority for signing server certificates (C implies lowercase c, hence you do not need to specify both).
  • T states that this certificate is a trusted authority for signing client certificates (T implies lowercase c, hence you do not need to specify both T and c).
To specify the trust flags for each position, join the letters with commas. For example, the option -t CT,C,c means that the certificate is trusted for signing client and server TLS certificates, signing server email certificates (S/MIME), and is a valid CA for object signing (though untrusted).
  • This ensures that, if this certificate signs another certificate, which in turn is used for object signing, it will be deemed invalid.
No trust (or the lack of trust) can be specified by using -t ,,.
To see the trust levels of all certificates in the database, run:
  • certutil -L -d
  • Each certificate's nickname will be listed and the trust flags will be specified at the end of the line.
See the notes about HSMs in the -h option.
Note that more trust levels are specified in the certutil manpage. To reference this documentation, please run the man certutil command on a system with certutil properly installed.
-h <HSM>
The -h <HSM> option specifies the name of the HSM to perform operations on.
-h option is incompatible with the -t option, as HSMs cannot store trust. Only an NSS DB can store trust, so using the certutil -A command or the certutil -M command in conjunction with -h <HSM> will fail. Instead, specify the desired trust level on a separate certutil -M command without the -h option.
Update this value as appropriate for your configuration.
-e
The -e option specifies that the validity of the signature is checked as well, when used in conjunction with the certutil -V command. PKICertImport always performs the certificate signature validation and does not understand the -e option.
-a
The -a option specifies that the key in question is in PEM (ASCII) format.
-i <certificate>
The -i <certificate> option specifies the path to the certificate. This is only used in the certutil -A command to specify the path to the certificate to import.
Update this value as appropriate for your configuration.
-u <usage>
The -u <usage> option specifies that usage of the certificate to verify when used in conjunction with the certutil -V command.
There are several usage letters referenced in the following sections.
  • -u C stands for verify a client TLS certificate. Note that this mostly accepts any certificate, but will check expiration date and signature.
  • -u V stands for verify a server TLS certificate. Note that this will reject CA certificates and will check expiration date and signature.
  • -u L stands for verify a CA TLS certificate. Note that this will validate trust flags (to see if c is present) and will check key usage to ensure that the key is a CA key. This also checks expiration and signatures.
  • -u O stands for verify a OCSP status responder certificate. Note that this checks expiry and signatures.
  • -u J stands for verify an object signing certificate. Note that this checks expiry and signatures.
If the wrong usage option is specified or the trust flags on the certificate are wrong (such as a missing c flag for an CA TLS certificate), certutil -V will give incorrect results.

Note

More usage options are specified in the certutil manpage. To reference this documentation, run the man certutil command on a system with certutil properly installed.

11.2. Importing a Root Certificate
Copy link

First, change directories into the NSS DB:
  • cd /path/to/nssdb
Ensure that your web service is taken offline (stopped, disabled, etc.) while performing these steps and ensure no concurrent access to the NSS DB by other processes (such as a browser). Doing so may corrupt the NSS DB or result in improper usage of these certificates.
When needing to import a new root certificate, ensure you acquire this certificate in a secure manner as it will be able to sign a number of certificates. We assume you already have it in a file named ca_root.crt. Please substitute the correct name and path to this file as appropriate for your scenario.
For more information about the certutil and PKICertImport options used below, see Section 11.1, “About certutil and PKICertImport”.
To import the root certificate:
  • Execute PKICertImport -d . -n "CA Root" -t "CT,C,C" -a -i ca_root.crt -u L command.
    This command validates and imports the root certificate into your NSS DB. The validation succeeds when no error message is printed and the return code is 0. To check the return code, execute echo $? immediately after executing the previous command above. In most cases, a visual error message is printed. The certificate usually fails to validate because it is expired or because it is not a CA certificate. Therefore, make sure your certificate file is correct and up-to-date. Contact the issuer and ensure that all intermediate and root certificates are present on your system.

11.3. Importing an Intermediate Certificate Chain
Copy link

Before beginning, please change directories into the NSS DB:
  • cd /path/to/nssdb
Ensure that your web service is offline (stopped, disabled, etc.) while performing these steps and ensure no concurrent access to the NSS DB by other processes (such as a browser). Doing so may corrupt the NSS DB or result in improper usage of these certificates.
If you have not imported and trusted the root certificate, see Section 11.2, “Importing a Root Certificate”.
When given a series of intermediate certificates between your root and end server or client certificates, we need to import and validate the signed certificate chain in order from closest to furthest from the root CA certificate. We assume the Intermediate CAs are in files named ca_sub_<num>.crt (for example ca_sub_1.crt, ca_sub_2.crt, and so on). Substitute names and paths for your certificates as appropriate to your deployment.

Note

In the unlikely scenario that you are instead given a single file named fullchain.crt, fullchain.pem, or similar and it contains multiple certificates, split it into the above format by copying each block (between and including the ----BEGIN CERTIFICATE----- and an -----END CERTIFICATE----- markers) to its own file. The first ones should be named ca_sub_<num>.crt and the last will be your server cert named service.crt. Server certificates are discussed in later sections.
First, we will import and validate any intermediate CAs in order of closest to furthest from the root CA certificate. If you don't have any, you can skip to the next section.
For more information about the certutil and PKICertImport options used below, see Section 11.1, “About certutil and PKICertImport”.
For every intermediate certificate in the chain:
  • Execute PKICertImport -d . -n "CA Sub $num" -t "CT,C,C" -a -i ca_sub_$num.crt -u L
    This command validates and imports the Intermediate CA certificate into your NSS DB. The validation succeeds when no error message is printed and the return code is 0. To check the return code, execute echo $? immediately after executing the previous command above. In most cases, a visual error message is printed. If the validation does not succeed, contact the issuer and ensure that all intermediate and root certificates are present on your system.

11.4. Importing a certificate into an NSS Database
Copy link

Ensure that your web service is taken offline (stopped, disabled, etc.) while performing these steps and ensure no concurrent access to the NSS database by other processes (such as a browser). Doing so may corrupt the NSS database or result in improper usage of these certificates.
Note that which set of instructions you follow will depend on the usage for the certificate in question.
  • For any subsystem's auditSigningCert, please follow the steps below for validating an object Signing certificate.
  • For the CA subsystem's caSigningCert, please follow the steps above for importing and validating an intermediate certificate chain, but do so only with the caSigningCert.
  • For the CA subsystem's ocspSigningCert, please follow the steps below for validating an OCSP certificate.
  • For user's client or S/MIME certificate, follow the Client Certificate steps.
For more information about the certutil and PKICertImport options used below, see Section 11.1, “About certutil and PKICertImport”.
Importing a Client Certificate Into the NSS Database

In most cases, a visual error message is printed. If the validation does not succeed, contact the issuer and ensure that all intermediate and root certificates are present on your system.
This chapter explains how to set up authorization for access to the administrative, agent services, and end-entities pages.

12.1. About Authorization
Copy link

Note

The ACLs associated with each group discussed in this section must not be modified.
Authorization is the process of allowing access to certain tasks associated with the Certificate System. Access can be limited to allow certain tasks to certain areas of the subsystem for certain users or groups and different tasks to different users and groups.
Users are specific to the subsystem in which they are created. Each subsystem has its own set of users independent of any other subsystem installed. The users are placed in groups, which can be predefined or user-created. Privileges are assigned to a group through access control lists (ACLs). There are ACLs associated with areas in the administrative console, agent services interface, and end-entities page that perform an authorization check before allowing an operation to proceed. Access control instructions (ACIs) in each of the ACLs are created that specifically allow or deny possible operations for that ACL to specified users, groups, or IP addresses.
The ACLs contain a default set of ACIs for the default groups that are created.
Authorization goes through the following process:
  1. The users authenticate to the interface using a certificate.
  2. The server authenticates the user by checking the certificate against one stored in the database. The server also checks that the certificate is valid and finds the group membership of the user by associating the DN of the certificate with a user and checking the user entry.
  3. When the user tries to perform an operation, the authorization mechanism compares the user ID of the user, the group in which the user belongs, or the IP address of the user to the ACLs set for that user, group, or IP address. If an ACL exists that allows that operation, then the operation proceeds.

12.2. Default Groups
Copy link

A user's privileges are determined by the group (role) membership of the user. There are three groups (roles) that a user can be assigned to:
  • Administrators. This group is given full access to all of the tasks available in the administrative interface.
  • Agents. This group is given full access to all of the tasks available in the agent services interface.
  • Auditors. This group is given access to view the signed audit logs. This group does not have any other privileges.
There is a fourth role that is exclusively created for communication between subsystems. Administrators should never assign a real user to such a role:
  • Enterprise administrators. Each subsystem instance is automatically assigned a subsystem-specific role as an enterprise administrator when it is joined to a security domain during configuration. These roles automatically provide trusted relationships among subsystems in the security domain, so that each subsystem can efficiently carry out interactions with other subsystems.

12.2.1. Administrators
Copy link

Administrators have permissions to perform all administrative tasks. A user is designated or identified as being an administrator by being added to the Administrators group for the group. Every member of that group has administrative privileges for that instance of Certificate System.
At least one administrator must be defined for each Certificate System instance, but there is no limit to the number of administrators an instance can have. The first administrator entry is created when the instance is configured.
Administrators are authenticated with a simple bind using their Certificate System user ID and password.

Table 12.1. Security Domain User Roles
Role Description
Security Domain Administrators
  • Add and modify users in the security domain's user and group database.
  • Manage the shared trust policies.
  • Manage the access controls on the domain services.
By default, the CA administrator of the CA hosting the domain is assigned as the security domain administrator.
Enterprise CA Administrators
  • Automatically approve any sub-CA, server, and subsystem certificate from any CA in the domain.
  • Register and unregister CA subsystem information in the security domain.
Enterprise KRA Administrators
  • Automatically approve any transport, storage, server, and subsystem certificate from any CA in the domain.
  • Register and unregister KRA subsystem information in the security domain.
  • Push KRA connector information to any CA.
Enterprise OCSP Administrators
  • Automatically approve any OCSP, server, and subsystem certificate from any CA in the domain.
  • Register and unregister OCSP subsystem information in the security domain.
  • Push CRL publishing information to any CA.
Enterprise TKS Administrators
  • Automatically approve any server and subsystem certificate from any CA in the domain.
  • Register and unregister TKS subsystem information in the security domain.
Enterprise TPS Administrators
  • Automatically approve any server and subsystem certificate from any CA in the domain.
  • Register and unregister TPS subsystem information in the security domain.
As necessary, the security domain administrator can manage access controls on the security domain and on the individual subsystems. For example, the security domain administrator can restrict access so that only finance department KRA administrators can set up finance department KRAs.
Enterprise subsystem administrators are given enough privileges to perform operations on the subsystems in the domain. For example, an enterprise CA administrator has the privileges to have sub-CA certificates approved automatically during configuration. Alternatively, a security domain administrator can restrict this right if necessary.

12.2.2. Auditors
Copy link

An auditor can view the signed audit logs and is created to audit the operation of the system. The auditor cannot administer the server in any way.
An auditor is created by adding a user to the Auditors group and storing the auditor's certificate in the user entry. The auditor's certificate is used to encrypt the private key of the key pair used to sign the audit log.
The Auditors group is set when the subsystem is configured. No auditors are assigned to this group during configuration.

12.2.3. Agents
Copy link

Agents are users who have been assigned end-entity certificate and key-management privileges. Agents can access the agent services interface.
Agents are created by assigning a user to the appropriate subsystem agent group and identifying certificates that the agents must use for TLS client authentication to the subsystem for it to service requests from the agents. Each subsystem has its own agent group:
  • The Certificate Manager Agents group.
  • The Key Recovery Authority Agents group.
  • The Online Certificate Status Manager Agents group.
  • The Token Key Service Agents group.
  • The Token Processing System Agents group.
Each Certificate System subsystem has its own agents with roles defined by the subsystem. Each subsystem must have at least one agent, but there is no limit to the number of agents a subsystem can have.
Certificate System identifies and authenticates a user with agent privileges by checking the user's TLS client certificate in its internal database.

12.2.4. Enterprise Groups
Copy link

Note

No real user should ever be asigned to this group.
During subsystem configuration, every subsystem instance is joined to a security domain. Each subsystem instance is automatically assigned a subsystem-specific role as an enterprise administrator. These roles automatically provide trusted relationships among subsystems in the security domain, so that each subsystem can efficiently carry out interactions with other subsystems. For example, this allows OCSPs to push CRL publishing publishing information to all CAs in the domain, KRAs to push KRA connector information, and CAs to approve certificates generated within the CA automatically.
Enterprise subsystem administrators are given enough privileges to perform operations on the subsystems in the domain. Each subsystem has its own security domain role:
  • Enterprise CA Administrators
  • Enterprise KRA Administrators
  • Enterprise OCSP Administrators
  • Enterprise TKS Administrators
  • Enterprise TPS Administrators
Additionally, there is a Security Domain Administrators group for the CA instance which manages the security domain, access control, users, and trust relationships within the domain.
Each subsystem administrator authenticates to the other subsystems using TLS client authentication with the subsystem certificate issued during configuration by the security domain CA.
Many of the operations that users can perform are dictated by the groups that they belong to; for instance, agents for the CA manage certificates and profiles, while administrators manage CA server configuration.
Four subsystems — the CA, OCSP, KRA, and TKS — use the Java administrative console to manage groups and users. The TPS has web-based admin services, and users and groups are configured through its web service page.

12.3.1. Managing Groups
Copy link

12.3.1.1. Creating a New Group
Copy link
  1. Log into the administrative console. 
    pkiconsole https://server.example.com:8443/subsystem_type
    Copy to Clipboard Toggle word wrap
  2. Select Users and Groups from the navigation menu on the left.
  3. Select the Groups tab.
  4. Click Edit, and fill in the group information.
    View larger image
    It is only possible to add users who already exist in the internal database.
  5. Edit the ACLs to grant the group privileges. See Section 12.4.3, “Editing ACLs” for more information. If no ACIs are added to the ACLs for the group, the group will have no access permissions to any part of Certificate System.
12.3.1.2. Changing Members in a Group
Copy link
Members can be added or deleted from all groups. The group for administrators must have at least one user entry.
  1. Log into the administrative console.
  2. Select Users and Groups from the navigation tree on the left.
  3. Click the Groups tab.
  4. Select the group from the list of names, and click Edit.
  5. Make the appropriate changes.
    • To change the group description, type a new description in the Group description field.
    • To remove a user from the group, select the user, and click Delete.
    • To add users, click Add User. Select the users to add from the dialog box, and click OK.
The users for each subsystem are maintained separately. Just because a person is an administrator in one subsystem does not mean that person has any rights (or even a user entry) for another subsystem. Users can be configured and, with their user certificates, trusted as agents, administrators, or auditors for a subsystem.
12.3.2.1. Creating Users
Copy link
After you installed Certificate System, only the user created during the setup exists. This section describes how to create additional users.

Note

For security reasons and audit trails, create individual accounts for Certificate System users and administrators.
12.3.2.1.1. Creating Users Using the Command Line
Copy link
To create a user using the command line:
  1. Add a user account. For example, to add the example user to the CA: 
    # pki -c password -n caadmin \
     ca-user-add example --fullName "Example User"
---------------------
Added user "example"
---------------------
  User ID: example
  Full name: Example User
    Copy to Clipboard Toggle word wrap
    This command uses the caadmin user to add a new account.
  2. Optionally, add a user to a group. For example, to add the example user to the Certificate Manager Agents group: 
    # pki -p password -n "caadmin" \
     user-add-membership example Certificate Manager Agents
    Copy to Clipboard Toggle word wrap
  3. Create a certificate request:
    • If a Key Recovery Authority (KRA) exists in your Certificate System environment: 
      # CRMFPopClient -d ~/.dogtag/pki-instance_name/ -p password \
     -n "user_name" -q POP_SUCCESS -b kra.transport -w "AES/CBC/PKCS5Padding" \
     -v -o ~/user_name.req
      Copy to Clipboard Toggle word wrap
      This command stores the Certificate Signing Request (CSR) in the CRMF format in the ~/user_name.req file.
    • If no Key Recovery Authority (KRA) exists in your Certificate System environment: 
      # PKCS10Client -d ~/.dogtag/pki-instance_name/ -p password \
     -n "user_name" -o ~/user_name.req
      Copy to Clipboard Toggle word wrap
      This command stores the CSR in pkcs10 format in the ~/user_name.req file.
  4. Create an enrollment request:
    1. Create the ~/cmc.role_crmf.cfg file with the following content: 
      #numRequests: Total number of PKCS10 requests or CRMF requests.
numRequests=1

#input: full path for the PKCS10 request or CRMF request,
#the content must be in Base-64 encoded format
#Multiple files are supported. They must be separated by space.
input=~/user_name.req

#output: full path for the CMC request in binary format
output=~/cmc.role_crmf.req

#tokenname: name of token where agent signing cert can be found (default is internal)
tokenname=internal

#nickname: nickname for agent certificate which will be used
#to sign the CMC full request.
nickname=PKI Administrator for Example.com

#dbdir: directory for cert8.db, key3.db and secmod.db
dbdir=~/.dogtag/pki-instance_name/

#password: password for cert8.db which stores the agent
#certificate
password=password

#format: request format, either pkcs10 or crmf
format=crmf
      Copy to Clipboard Toggle word wrap
      Set the parameters based on your environment and the CSR format used in the previous step.
    2. Pass the previously created configuration file to the CMCRequest utility to create the CMC request: 
      # CMCRequest ~/cmc.role_crmf.cfg
      Copy to Clipboard Toggle word wrap
  5. Submit a Certificate Management over CMS (CMC) request:
    1. Create the ~/HttpClient_role_crmf.cfg file with the following content: 
      # #host: host name for the http server
host=server.example.com

#port: port number
port=8443

#secure: true for secure connection, false for nonsecure connection
secure=true

#input: full path for the enrollment request, the content must be in binary format
input=~/cmc.role_crmf.req

#output: full path for the response in binary format
output=~/cmc.role_crmf.resp

#tokenname: name of token where TLS client authentication cert can be found (default is internal)
#This parameter will be ignored if secure=false
tokenname=internal

#dbdir: directory for cert8.db, key3.db and secmod.db
#This parameter will be ignored if secure=false
dbdir=~/.dogtag/pki-instance_name/

#clientmode: true for client authentication, false for no client authentication
#This parameter will be ignored if secure=false
clientmode=true

#password: password for cert8.db
#This parameter will be ignored if secure=false and clientauth=false
password=password

#nickname: nickname for client certificate
#This parameter will be ignored if clientmode=false
nickname=PKI Administrator for Example.com

#servlet: servlet name
servlet=/ca/ee/ca/profileSubmitCMCFull
      Copy to Clipboard Toggle word wrap
      Set the parameters based on your environment.
    2. Submit the request to the CA: 
      # HttpClient ~/HttpClient_role_crmf.cfg
Total number of bytes read = 3776
after SSLSocket created, thread token is Internal Key Storage Token
client cert is not null

  6. Optionally, to import the certificate as the user to its own ~/.dogtag/pki-instance_name/ database: 
    # certutil -d ~/.dogtag/pki-instance_name/ -A -t "u,u,u" -n "user_name certificate" -i ~/cmc.role_crmf.resp
    Copy to Clipboard Toggle word wrap
  7. Add the certificate to the user record:
    1. List certificates issued for the user to discover the certificate's serial number. For example, to list certificates that contain the example user name in the certificate's subject: 
      pki -c password -n caadmin ca-user-cert-find example
-----------------
1 entries matched
-----------------
  Cert ID: 2;6;CN=CA Signing Certificate,O=EXAMPLE;CN=PKI Administrator,E=example@example.com,O=EXAMPLE

  Subject: CN=PKI Administrator,E=example@example.com,O=EXAMPLE
----------------------------
Number of entries returned 1
      Copy to Clipboard Toggle word wrap
      The serial number of the certificate is required in the next step.
    2. Add the certificate using its serial number from the certificate repository to the user account in the Certificate System database. For example, for a CA user: 
      pki -c password -n caadmin ca-user-cert-add example --serial 0x6
      Copy to Clipboard Toggle word wrap
12.3.2.1.2. Creating Users Using the Console
Copy link
To create a user using the PKI Console:
  1. Log into the administrative console. 
    pkiconsole https://server.example.com:8443/subsystem_type
    Copy to Clipboard Toggle word wrap
  2. In the Configuration tab, select Users and Groups. Click Add.
  3. Fill in the information in the Edit User Information dialog.
    View larger image
    Most of the information is standard user information, such as the user's name, email address, and password. This window also contains a field called User State, which can contain any string, which is used to add additional information about the user; most basically, this field can show whether this is an active user.
  4. Select the group to which the user will belong. The user's group membership determines what privileges the user has. Assign agents, administrators, and auditors to the appropriate subsystem group.
  5. Store the user's certificate.
    1. Request a user certificate through the CA end-entities service page.
    2. If auto-enrollment is not configured for the user profile, then approve the certificate request.
    3. Retrieve the certificate using the URL provided in the notification email, and copy the base-64 encoded certificate to a local file or to the clipboard.
    4. Select the new user entry, and click Certificates.
    5. Click Import, and paste in the base-64 encoded certificate.
  1. Log into the administrative console.
  2. Select Users and Groups.
  3. Select the user to edit from the list of user IDs, and click Certificates.
  4. Click Import to add the new certificate.
  5. In the Import Certificate window, paste the new certificate in the text area. Include the -----BEGIN CERTIFICATE----- and -----END CERTIFICATE----- marker lines.
There are two methods of renewing a certificate. Regenerating the certificate takes its original key and its original profile and request, and recreates an identical key with a new validity period and expiration date. Re-keying a certificate resubmits the initial certificate request to the original profile, but generates a new key pair. Administrator certificates can be renewed by being re-keyed.
Each subsystem has a bootstrap administrator user that was created at the time the subsystem was created. A new certificate can be requested for this user before their original one expires, using one of the default renewal profiles.
Certificates for administrative users can be renewed directly in the end user enrollment forms, using the serial number of the original certificate.
  1. Renew the admin user certificate. For details, seeSection 5.4, “Renewing Certificates”.
  2. Add the renewed user certificate to the user entry in the internal LDAP database.
    1. Open the console for the subsystem. 
      pkiconsole https://server.example.com:admin_port/subsystem_type
      Copy to Clipboard Toggle word wrap
    2. Configuration | Users and Groups | Users | admin | Certificates | Import
    3. In the Configuration tab, select Users and Groups.
    4. In the Users tab, double-click the user entry with the renewed certificate, and click Certificates.
    5. Click Import, and paste in the base-64 encoded certificate.
    This can also be done by using ldapmodify to add the renewed certification directly to the user entry in the internal LDAP database, by replacing the userCertificate attribute in the user entry, such as uid=admin,ou=people,dc=subsystem-base-DN.
12.3.2.4. Deleting a Certificate System User
Copy link
Users can be deleted from the internal database. Deleting a user from the internal database deletes that user from all groups to which the user belongs. To remove the user from specific groups, modify the group membership.
Delete a privileged user from the internal database by doing the following:
  1. Log into the administrative console.
  2. Select Users and Groups from the navigation menu on the left.
  3. Select the user from the list of user IDs, and click Delete.
  4. Confirm the delete when prompted.

12.4. Configuring Access Control for Users
Copy link

Authorization is the mechanism that checks whether a user is allowed to perform an operation. Authorization points are defined in certain groups of operations that require an authorization check.

12.4.1. About Access Control

Access control lists (ACLs) are the mechanisms that specify the authorization to server operations. An ACL exists for each set of operations where an authorization check occurs. Additional operations can be added to a ACL.
The ACL contains access control instructions (ACIs) which specifically allow or deny operations, such as read or modify. The ACI also contains an evaluator expression. The default implementation of ACLs specifies only users, groups, and IP addresses as possible evaluator types. Each ACI in an ACL specifies whether access is allowed or denied, what the specific operator is being allowed or denied, and which users, groups, or IP addresses are being allowed or denied to perform the operation.
The privileges of Certificate System users are changed by changing the access control lists (ACL) that are associated with the group in which the user is a member, for the users themselves, or for the IP address of the user. New groups are assigned access control by adding that group to the access control lists. For example, a new group for administrators who are only authorized to view logs, LogAdmins, can be added to the ACLs relevant to logs to allow read or modify access to this group. If this group is not added to any other ACLs, members of this group only have access to the logs.
The access for a user, group, or IP address is changed by editing the ACI entries in the ACLs. In the ACL interface, each ACI is shown on a line of its own. In this interface window, the ACI has the following syntax: 
allow|deny (operation) user|group|IP="name"
Copy to Clipboard Toggle word wrap

Note

The IP address can be an IPv4 or IPv6 address. An IPv4 address must be in the format n.n.n.n or n.n.n.n,m.m.m.m. For example, 128.21.39.40 or 128.21.39.40,255.255.255.00. An IPv6 address uses a 128-bit namespace, with the IPv6 address separated by colons and the netmask separated by periods. For example, 0:0:0:0:0:0:13.1.68.3, FF01::43, 0:0:0:0:0:0:13.1.68.3,FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:255.255.255.0, and FF01::43,FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FF00:0000.
For example, the following is an ACI that allows administrators to perform read operations: 
allow (read) group="Administrators"
Copy to Clipboard Toggle word wrap
An ACI can have more than one operation or action configured. The operations are separated with a comma with no space on either side. For example: 
allow (read,modify) group="Administrators"
Copy to Clipboard Toggle word wrap
An ACI can have more than one group, user, or IP address by separating them with two pipe symbols (||) with a space on either side. For example: 
allow (read) group="Administrators" || group="Auditors"
Copy to Clipboard Toggle word wrap
The administrative console can create or modify ACIs. The interface sets whether to allow or deny the operation in the Allow and Deny field, sets which operations are possible in the Operations field, and then lists the groups, users, or IP addresses being granted or denied access in the Syntax field.
An ACI can either allow or deny an operation for the specified group, user ID, or IP address. Generally, ACIs do not need to be created to deny access. If there are no allow ACIs that include a user ID, group, or IP address, then the group, user ID, or IP address is denied access.

Note

If a user is not explicitly allowed access to any of the operations for a resource, then this user is considered denied; he does not specifically need to be denied access.
For example, user JohnB is a member of the Administrators group. If an ACL has only the following ACL, JohnB is denied any access since he does not match any of the allow ACIs: 
Allow (read,modify) group="Auditors" || user="BrianC"
Copy to Clipboard Toggle word wrap
There usually is no need to include a deny statement. Some situations can arise, however, when it is useful to specify one. For example, JohnB, a member of the Administrators group, has just been fired. It may be necessary to deny access specifically to JohnB if the user cannot be deleted immediately. Another situation is that a user, BrianC, is an administrator, but he should not have the ability to change some resource. Since the Administrators group must access this resource, BrianC can be specifically denied access by creating an ACI that denies this user access.
The allowed rights are the operations which the ACI controls, either by allowing or denying permission to perform the operation. The actions that can be set for an ACL vary depending on the ACL and subsystem. Two common operations that can be defined are read and modify.
The syntax field of the ACI editor sets the evaluator for the expression. The evaluator can specify group, name, and IP address (both IPv4 and IPv6 addresses). These are specified along with the name of the entity set as equals (=) or does not equal (!=).
The syntax to include a group in the ACL is group="groupname". The syntax to exclude a group is group!="groupname", which allows any group except for the group named. For example: 
group="Administrators" || group!="Auditors"
Copy to Clipboard Toggle word wrap
It is also possible to use regular expressions to specify the group, such as using wildcard characters like an asterisk (*). For example: 
group="* Managers"
Copy to Clipboard Toggle word wrap
For more information on supported regular expression patterns, see https://docs.oracle.com/javase/7/docs/api/java/util/regex/Pattern.html.
The syntax to include a user in the ACL is user="userID". The syntax to exclude the user is user!="userID", which allows any user ID except for the user ID named. For example: 
user="BobC" || user!="JaneK"
Copy to Clipboard Toggle word wrap
To specify all users, provide the value anybody. For example: 
user="anybody"
Copy to Clipboard Toggle word wrap
It is also possible to use regular expressions to specify the user names, such as using wildcard characters like an asterisk (*). For example: 
user="*johnson"
Copy to Clipboard Toggle word wrap
For more information on supported regular expression patterns, see https://docs.oracle.com/javase/7/docs/api/java/util/regex/Pattern.html.
The syntax to include an IP address in the ACL is ipaddress="ipaddress". The syntax to exclude an ID address from the ACL is ipaddress!="ipaddress". An IP address is specified using its numeric value; DNS values are not permitted. For example: 
ipaddress="12.33.45.99"
ipaddress!="23.99.09.88"
Copy to Clipboard Toggle word wrap
The IP address can be an IPv4 address, as shown above, or IPv6 address. An IPv4 address has the format n.n.n.n or n.n.n.n,m.m.m.m with the netmask. An IPv6 address uses a 128-bit namespace, with the IPv6 address separated by colons and the netmask separated by periods. For example: 
ipaddress="0:0:0:0:0:0:13.1.68.3"

Chapter 13. Configuring Subsystem Logs
Copy link

For an overview on logs, see the Logs section under the Certificate System Architecture Overview section in the Red Hat Certificate System 9 Planning, Installation and Deployment Guide (Common Criteria Edition).
For log configuration during the installation and additional information, see the Configuring Logs section in the Red Hat Certificate System 9 Planning, Installation and Deployment Guide (Common Criteria Edition).

13.1. Managing Logs
Copy link

The Certificate System subsystem log files record events related to operations within that specific subsystem instance. For each subsystem, different logs are kept for issues such as installation, access, and web servers.
All subsystems have similar log configuration, options, and administrative paths.

13.1.1. Configuring Logs in the Console
Copy link

Logs can be configured through the subsystem Console. Specialized logs, such as signed audit logs and custom logs, can also be created through the Console or configuration file.
  1. In the navigation tree of the Configuration tab, select Log.
  2. The Log Event Listener Management tab lists the currently configured listeners.
    To create a new log instance, click Add, and select a module plug-in from the list in the Select Log Event Listener Plug-in Implementation window.
  3. Set or modify the fields in the Log Event Listener Editor window. The different parameters are listed in Table 13.1, “Log Event Listener Fields”.
Expand
Table 13.1. Log Event Listener Fields
Field Description
Log Event Listener ID Gives the unique name that identifies the listener. The names can have any combination of letters (aA to zZ), digits (0 to 9), an underscore (_), and a hyphen (-), but it cannot contain other characters or spaces.
type Gives the type of log file. system creates error and system logs; transaction records audit logs.
enabled Sets whether the log is active. Only enabled logs actually record events. The value is either true or false.
level Sets the log level in the text field. The level must be manually entered in the field; there is no selection menu. The choices are Debug, Information, Warning, Failure, Misconfiguration, Catastrophe, and Security.
fileName Gives the full path, including the file name, to the log file. The subsystem user should have read/write permission to the file.
bufferSize Sets the buffer size in kilobytes (KB) for the log. Once the buffer reaches this size, the contents of the buffer are flushed out and copied to the log file. The default size is 512 KB.
flushInterval Sets the amount of time before the contents of the buffer are flushed out and added to the log file. The default interval is 5 seconds.
maxFileSize Sets the size, in kilobytes (KB), a log file can become before it is rotated. Once it reaches this size, the file is copied to a rotated file, and the log file is started new. The default size is 2000 KB.
rolloverInterval Sets the frequency for the server to rotate the active log file. The available options are hourly, daily, weekly, monthly, and yearly. The default is monthly.

13.1.2. Managing Audit Logs
Copy link

The audit log contains audit records for events that have been set up as recordable events. If you enabled the audit log signing option as described in the Enabling and Configuring Signed Audit Logs section in the Red Hat Certificate System 9 Planning, Installation and Deployment Guide (Common Criteria Edition), the audit log is signed with a log signing certificate belonging to the server. This certificate can be used by auditors to verify that the log has not been tampered with.

Note

Signed audit logs are optional. To enable them, please refer to Section 13.1.2.1, “Configuring a Signed Audit Log in the Console”.
By default, regular audit logs are located in the /var/log/pki/instance_name/subsystem_name/ directory with other types of logs, while signed audit logs are written to /var/log/pki/instance_name/subsystem_name/signedAudit/. The default location for logs can be changed by modifying the configuration.
The signed audit log creates a log recording system events, and the events are selected from a list of potential events. When enabled, signed audit logs record a verbose set of messages about the selected event activity.
It is also possible to edit the configuration or change the signing certificates after configuration, as covered in Section 13.1.2.1, “Configuring a Signed Audit Log in the Console”.
Signed audit logs are configured by default when the instance is first created, but it is possible to edit the configuration or change the signing certificates after the installation.

Note

Provide enough space in the file system for the signed audit logs, since they can be large.
A log is set to a signed audit log by setting the logSigning parameter to enable and providing the nickname of the certificate used to sign the log. A special log signing certificate is created when the subsystems are first configured.
Only a user with auditor privileges can access and view a signed audit log. Auditors can use the AuditVerify tool to verify that signed audit logs have not been tampered with.
The signed audit log is created and enabled when the subsystem is configured, but it needs additional configuration to begin creating and signing audit logs.
  1. Open the Console.
  2. In the navigation tree of the Configuration tab, select Log.
  3. In the Log Event Listener Management tab, select the SignedAudit entry.
  4. Click Edit/View.
  5. There are two fields which must be reset in the Log Event Listener Editor window.
    • Set the logSigning field to true to enable signed logging.

      Note

      For more fine-grained audit event select, set audit event filters during the installation configuration. For details, see the Filtering Audit Events section in the Red Hat Certificate System Planning, Installation, and Deployment Guide (Common Criteria Edition).
    • Set any events which are logged to the audit log. Appendix E, Audit Events lists the loggable events. Log events are separated by commas with no spaces.
  6. Save the log configuration.
After enabling signed audit logging, assign auditor users by creating the user and assigning that entry to the auditor group. Members of the auditor group are the only users who can view and verify the signed audit log. See Section 12.3.2.1, “Creating Users” for details about setting up auditors.
Auditors can verify logs by using the AuditVerify tool. See the AuditVerify(1) man page for details about using this tool. For further details, see Section 13.2.2, “Using Signed Audit Logs”.
13.1.2.2. Handling Audit Logging Failures
Copy link
There are events that could cause the audit logging function to fail, so events cannot be written to the log. For example, audit logging can fail when the file system containing the audit log file is full or when the file permissions for the log file are accidentally changed.
If log signing is enabled and audit logging fails, the Certificate System instance shuts down in the following manner.
  • Servlets are disabled and will not process new requests.
  • All pending and new requests are killed.
  • The subsystem is shut down.
When this happens, administrators and auditors should work together with the operating system administrator to resolve the disk space or file permission issues. When the IT problem is resolved, the auditor should make sure that the last audit log entries are signed. When this is completed, the administrators can restart the Certificate System.

13.2.1. Viewing Logs in the Console
Copy link

To troubleshoot the subsystem, check the error or informational messages that the server has logged. Examining the log files can also monitor many aspects of the server's operation. Some log files can be viewed through the Console. However, the audit log is only accessible by users with the Auditor role, using a method detailed in Section 13.2.2, “Using Signed Audit Logs”.
To view the contents of an active or rotated system log file:
  1. Log into the Console.
  2. Select the Status tab.
  3. Under Logs, select the log to view.
  4. Set the viewing preferences in the Display Options section.
    • Entries — The maximum number of entries to be displayed. When this limit is reached, the Certificate System returns any entries that match the search request. Zero (0) means no messages are returned. If the field is blank, the server returns every matching entry, regardless of the number found.
    • Source — Select the Certificate System component or service for which log messages are to be displayed. Choosing All means messages logged by all components that log to this file are displayed.
    • Level — Select a message category that represents the log level for filtering messages.
    • Filename — Select the log file to view. Choose Current to view the currently active system log file.
  5. Click Refresh.
    The table displays the system log entries. The entries are in reverse chronological order, with the most current entry placed at the top. Use the scroll arrows on the right edge of the panel to scroll through the log entries.
    Each entry has the following information shown:
    • Source — The component or resource that logged the message.
    • Level — The severity of the corresponding entry.
    • Date — The date on which the entry was logged.
    • Time — The time at which the entry was logged.
    • Details — A brief description of the log.
  6. To view a full entry, double-click it, or select the entry, and click View.

The command uses the client certificate with the auditor nickname stored in the ~/.dogtag/nssdb/ directory for authenticating to the CA. For further details about the parameters used in the command and alternative authentication methods, see the pki(1) man page.
13.2.2.2. Downloading Audit Logs
Copy link
As a user with auditor privileges, use the pki subsystem-audit-file-retrieve command to download a specific audit log from the server.
For example, to download an audit log file from the CA hosted on server.example.com:
  1. Optionally, list the available log files on the CA. See Section 13.2.2.1, “Listing Audit Logs”.
  2. Download the log file. For example, to download the ca_audit file: 
    # pki -U https://server.example.com:8443 -n auditor ca-audit-file-retrieve ca_audit
    Copy to Clipboard Toggle word wrap
    The command uses the client certificate with the auditor nickname stored in the ~/.dogtag/nssdb/ directory for authenticating to the CA. For further details about the parameters used in the command and alternative authentication methods, see the pki(1) man page.
After downloading a log file, you can search for specific log entries, for example, using the grep utility:

Chapter 14. Managing Subsystem Certificates
Copy link

This chapter gives an overview of using certificates: what types and formats are available, how to request and create them through the HTML end-entity forms and through the Certificate System Console, and how to install certificates in the Certificate System and on different clients. Additionally, there is information on managing certificates through the Console and configuring the servers to use them.

14.1. Required Subsystem Certificates
Copy link

Each subsystem has a defined set of certificates which must be issued to the subsystem instance for it to perform its operations. There are certain details of the certificate contents that are set during the Certificate Manager configuration, with different considerations for constraints, settings, and attributes depending on the types of certificates; planning the formats of certificates is covered in the Types of Certificates section in the Red Hat Certificate System 9 Planning, Installation, and Deployment Guide (Common Criteria Edition).

14.1.1. Certificate Manager Certificates
Copy link

When a Certificate Manager is installed, the keys and requests for the CA signing certificate, TLS server certificate, and OCSP signing certificate are generated. The certificates are created before the configuration can be completed.
The CA certificate request is either submitted as a self-signing request to the CA, which then issues the certificate and finishes creating the self-signed root CA, or is submitted to a third-party public CA or another Certificate System CA. When the external CA returns the certificate, the certificate is installed, and installation of the subordinate CA is completed.
14.1.1.1. CA Signing Key Pair and Certificate
Copy link
Every Certificate Manager has a CA signing certificate with a public key corresponding to the private key the Certificate Manager uses to sign the certificates and CRLs it issues. This certificate is created and installed when the Certificate Manager is installed. The default nickname for the certificate is caSigningCert cert-instance_ID CA, where instance_ID identifies the Certificate Manager instance. The default validity period for the certificate is five years.
The subject name of the CA signing certificate reflects the name of the CA that was set during installation. All certificates signed or issued by the Certificate Manager include this name to identify the issuer of the certificate.
The Certificate Manager's status as a root or subordinate CA is determined by whether its CA signing certificate is self-signed or is signed by another CA, which affects the subject name on the certificates.
  • If the Certificate Manager is a root CA, its CA signing certificate is self-signed, meaning the subject name and issuer name of the certificate are the same.
  • If the Certificate Manager is a subordinate CA, its CA signing certificate is signed by another CA, usually the one that is a level above in the CA hierarchy (which may or may not be a root CA). The root CA's signing certificate must be imported into individual clients and servers before the Certificate Manager can be used to issue certificates to them.

Note

The CA name cannot  be changed or all previously-issued certificates are invalidated. Similarly, reissuing a CA signing certificate with a new key pair invalidates all certificates that were signed by the old key pair.
14.1.1.2. OCSP Signing Key Pair and Certificate
Copy link
The subject name of the OCSP signing certificate is in the form cn=OCSP cert-instance_ID CA, and it contains extensions, such as OCSPSigning and OCSPNoCheck, required for signing OCSP responses.
The default nickname for the OCSP signing certificate is ocspSigningCert cert-instance_ID, where instance_ID CA identifies the Certificate Manager instance.
The OCSP private key, corresponding to the OCSP signing certificate's public key, is used by the Certificate Manager to sign the OCSP responses to the OCSP-compliant clients when queried about certificate revocation status.
14.1.1.3. Subsystem Certificate
Copy link
Every member of the security domain is issued a server certificate to use for communications among other domain members, which is separate from the server TLS certificate. This certificate is signed by the security domain CA; for the security domain CA itself, its subsystem certificate is signed by itself.
The default nickname for the certificate is subsystemCert cert-instance_ID.
14.1.1.4. TLS Server Key Pair and Certificate
Copy link
Every Certificate Manager has at least one TLS server certificate that was first generated when the Certificate Manager was installed. The default nickname for the certificate is Server-Cert cert-instance_ID, where instance_ID identifies the Certificate Manager instance.
By default, the Certificate Manager uses a single TLS server certificate for authentication. However, additional server certificates can be requested to use for different operations, such as configuring the Certificate Manager to use separate server certificates for authenticating to the end-entity services interface and agent services interface.
If the Certificate Manager is configured for TLS-enabled communication with a publishing directory, it uses its TLS server certificate for client authentication to the publishing directory by default. The Certificate Manager can also be configured to use a different certificate for TLS client authentication.
The CA keeps a secure audit log of all events which occurred on the server. To guarantee that the audit log has not been tampered with, the log file is signed by a special log signing certificate.
The audit log signing certificate is issued when the server is first configured.

Note

While other certificates can use ECC keys, the audit signing certificate must always use an RSA key.
When the Online Certificate Status Manager is first configured, the keys for all required certificates are created, and the certificate requests for the OCSP signing, TLS server, audit log signing, and subsystem certificates are made. These certificate requests are submitted to a CA (either a Certificate System CA or a third-party CA) and must be installed in the Online Certificate Status Manager database to complete the configuration process.
14.1.2.1. OCSP Signing Key Pair and Certificate
Copy link
Every Online Certificate Status Manager has a certificate, the OCSP signing certificate, which has a public key corresponding to the private key the Online Certificate Status Manager uses to sign OCSP responses. The Online Certificate Status Manager's signature provides persistent proof that the Online Certificate Status Manager has processed the request. This certificate is generated when the Online Certificate Status Manager is configured. The default nickname for the certificate is ocspSigningCert cert-instance_ID, where instance_ID OSCP is the Online Certificate Status Manager instance name.
14.1.2.2. TLS Server Key Pair and Certificate
Copy link
Every Online Certificate Status Manager has at least one TLS server certificate which was generated when the Online Certificate Status Manager was configured. The default nickname for the certificate is Server-Cert cert-instance_ID, where instance_ID identifies the Online Certificate Status Manager instance name.
The Online Certificate Status Manager uses its server certificate for server-side authentication for the Online Certificate Status Manager agent services page.
The Online Certificate Status Manager uses a single server certificate for authentication purposes. Additional server certificates can be installed and used for different purposes.
14.1.2.3. Subsystem Certificate

Every member of the security domain is issued a server certificate to use for communications among other domain members, which is separate from the server TLS certificate. This certificate is signed by the security domain CA.
The default nickname for the certificate is subsystemCert cert-instance_ID.
The OCSP keeps a secure audit log of all events which occurred on the server. To guarantee that the audit log has not been tampered with, the log file is signed by a special log signing certificate.
The audit log signing certificate is issued when the server is first configured.

Note

While other certificates can use ECC keys, the audit signing certificate must always use an RSA key.
Depending on the CA which signed the Online Certificate Status Manager's TLS server certificate, it may be necessary to get the certificate and issuing CA recognized by the Certificate Manager.
  • If the Online Certificate Status Manager's server certificate is signed by the CA that is publishing CRLs, then nothing needs to be done.
  • If the Online Certificate Status Manager's server certificate is signed by the same root CA that signed the subordinate Certificate Manager's certificates, then the root CA must be marked as a trusted CA in the subordinate Certificate Manager's certificate database.
  • If the Online Certificate Status Manager's TLS server certificate is signed by a different root CA, then the root CA certificate must be imported into the subordinate Certificate Manager's certificate database and marked as a trusted CA.
If the Online Certificate Status Manager's server certificate is signed by a CA within the selected security domain, the certificate chain is imported and marked when the Online Certificate Status Manager is configured. No other configuration is required. However, if the server certificate is signed by an external CA, the certificate chain has to be imported for the configuration to be completed.

Note

Not every CA within the security domain is automatically trusted by the OCSP Manager when it is configured. Every CA in the certificate chain of the CA configured in the CA panel is, however, trusted automatically by the OCSP Manager. Other CAs within the security domain but not in the certificate chain must be added manually.

14.1.3. Key Recovery Authority Certificates
Copy link

The KRA uses the following key pairs and certificates:
14.1.3.1. Transport Key Pair and Certificate
Copy link
Every KRA has a transport certificate. The public key of the key pair that is used to generate the transport certificate is used by the client software to encrypt an end entity's private encryption key before it is sent to the KRA for archival; only those clients capable of generating dual-key pairs use the transport certificate.
14.1.3.2. Storage Key Pair
Copy link
Every KRA has a storage key pair. The KRA uses the public component of this key pair to encrypt (or wrap) private encryption keys when archiving the keys. It uses the private component to decrypt (or unwrap) the archived key during recovery. For more information on how this key pair is used, see Chapter 4, Setting up Key Archival and Recovery.
Keys encrypted with the storage key can be retrieved only by authorized key recovery agents.
14.1.3.3. TLS Server Certificate
Copy link
Every Certificate System KRA has at least one TLS server certificate. The first TLS server certificate is generated when the KRA is configured. The default nickname for the certificate is Server-Cert cert-instance_ID, where instance_id identifies the KRA instance is installed.
The KRA's TLS server certificate was issued by the CA to which the certificate request was submitted, which can be a Certificate System CA or a third-party CA. To view the issuer name, open the certificate details in the System Keys and Certificates option in the KRA Console.
The KRA uses its TLS server certificate for server-side authentication to the KRA agent services interface. By default, the Key Recovery Authority uses a single TLS server certificate for authentication. However, additional TLS server certificates can be requested and installed for the KRA.
14.1.3.4. Subsystem Certificate
Copy link
Every member of the security domain is issued a server certificate to use for communications among other domain members, which is separate from the server TLS certificate. This certificate is signed by the security domain CA.
The default nickname for the certificate is subsystemCert cert-instance_ID.
The KRA keeps a secure audit log of all events which occurred on the server. To guarantee that the audit log has not been tampered with, the log file is signed by a special log signing certificate.
The audit log signing certificate is issued when the server is first configured.

Note

While other certificates can use ECC keys, the audit signing certificate must always use an RSA key.

14.1.4. TKS Certificates
Copy link

The TKS has three certificates. The TLS server and subsystem certificates are used for standard operations. An additional signing certificate is used to protect audit logs.
14.1.4.1. TLS Server Certificate
Copy link
Every Certificate System TKS has at least one TLS server certificate. The first TLS server certificate is generated when the TKS is configured. The default nickname for the certificate is Server-Cert cert-instance_ID.
14.1.4.2. Subsystem Certificate
Copy link
Every member of the security domain is issued a server certificate to use for communications among other domain members, which is separate from the server TLS certificate. This certificate is signed by the security domain CA.
The default nickname for the certificate is subsystemCert cert-instance_ID.
The TKS keeps a secure audit log of all events which occurred on the server. To guarantee that the audit log has not been tampered with, the log file is signed by a special log signing certificate.
The audit log signing certificate is issued when the server is first configured.

Note

While other certificates can use ECC keys, the audit signing certificate must always use an RSA key.

14.1.5. TPS Certificates
Copy link

The TPS only uses three certificates: a server certificate, subsystem certificate, and audit log signing certificate.
14.1.5.1. TLS Server Certificate
Copy link
Every Certificate System TPS has at least one TLS server certificate. The first TLS server certificate is generated when the TPS is configured. The default nickname for the certificate is Server-Cert cert-instance_ID.
14.1.5.2. Subsystem Certificate
Copy link
Every member of the security domain is issued a server certificate to use for communications among other domain members, which is separate from the server TLS certificate. This certificate is signed by the security domain CA.
The default nickname for the certificate is subsystemCert cert-instance_ID.
The TPS keeps a secure audit log of all events which occurred on the server. To guarantee that the audit log has not been tampered with, the log file is signed by a special log signing certificate.
The audit log signing certificate is issued when the server is first configured.

14.1.6. About Subsystem Certificate Key Types
Copy link

When you create a new instance, you can specify the key type and key size in the configuration file passed to the pkispawn utility.

Example 14.1. Key Type-related Configuration Parameters for a CA

The following are key type-related parameters including example values. You can set these parameters in the configuration file which you pass to pkispawn when creating a new CA. 
pki_ocsp_signing_key_algorithm=SHA256withRSA
pki_ocsp_signing_key_size=2048
pki_ocsp_signing_key_type=rsa

pki_ca_signing_key_algorithm=SHA256withRSA
pki_ca_signing_key_size=2048
pki_ca_signing_key_type=rsa

pki_sslserver_key_algorithm=SHA256withRSA
pki_sslserver_key_size=2048
pki_sslserver_key_type=rsa

pki_subsystem_key_algorithm=SHA256withRSA
pki_subsystem_key_size=2048
pki_subsystem_key_type=rsa

pki_admin_keysize=2048
pki_admin_key_size=2048
pki_admin_key_type=rsa

pki_audit_signing_key_algorithm=SHA256withRSA
pki_audit_signing_key_size=2048
pki_audit_signing_key_type=rsa
Copy to Clipboard Toggle word wrap

Note

The values in the example are for a CA. Other subsystems require different parameters.
For further details, see:
  • The Understanding the pkispawn Utility section in the Red Hat Certificate System Planning, Installation, and Deployment Guide (Common Criteria Edition).
  • The pki_default.cfg(5) man page for descriptions of the parameters and examples.
By default, keys and certificates are stored in locally-managed databases, key3.db and cert8.db, respectively, in the /var/lib/pki/instance_name/alias/ directory. However, Red Hat Certificate System also supports hardware security modules (HSM), external devices which can store keys and certificates in a centralized place on the network. Using an HSM can make some functions, like cloning, easier because the keys and certificates for the instance are readily accessible.
When an HSM is used to store certificates, then the HSM name is prepended to the certificate nickname, and the full name is used in the subsystem configuration. For example: 
serverCert="nethsm:Server-Cert cert-instance_ID
Copy to Clipboard Toggle word wrap

Note

A single HSM can be used to store certificates and keys for mulitple subsystem instances, which may be installed on multiple hosts. When an HSM is used, any certificate nickname for a subsystem must be unique for every subsystem instance managed on the HSM.
Certificate System supports two types of HSM, nCipher netHSM and Chrysalis LunaSA.

14.2. Renewing Subsystem Certificates
Copy link

For details about renewing subsystem certificates, see Section 3.4.1, “About Renewal”.
The process for renewing a subsystem certificate is the same as for renewing a user certificate.
To renew a system certificate submit the request using the corresponding enrollment profile when using the HttpClient utility. For details about the different system certificate profiles, see Section 5.3.2.1, “Obtaining System and Server Certificates”.

14.2.1. Renewing Certificates Using certutil
Copy link

certutil can be used to generate a certificate request using an existing key pair in the certificate database. The new certificate request can then be converted to a CMC request to be submitted to the CA. For details, see Section 5.2.1, “Creating a CSR Using certutil”.

Note

Encryption and signing certificates are created in a single step. However, the renewal process only renews one certificate at a time.
To renew both certificates in a certificate pair, each one has to be renewed individually.
  1. Get the password for the token database. 
    cat /var/lib/pki/instance_name/conf/password.conf

internal=263163888660
    Copy to Clipboard Toggle word wrap
  2. Open the certificate database directory of the instance whose certificate is being renewed. 
    cd /var/lib/pki/instance_name/alias
    Copy to Clipboard Toggle word wrap
  3. List the key and nickname for the certificate being renewed. In order to renew a certificate, the key pairs used to generate and the subject name given to the new certificate must be the same as the one in the old certificate. 
    # certutil -K -d .

certutil: Checking token "NSS Certificate DB" in slot "NSS User Private Key and Certificate Services"
Enter Password or Pin for "NSS Certificate DB":
< 0> rsa      69481646e38a6154dc105960aa24ccf61309d37d   caSigningCert cert-pki-tomcat CA
    Copy to Clipboard Toggle word wrap
  4. Copy the alias directory as a backup, then delete the original certificate from the certificate database. For example: 
    certutil -D -n "ServerCert cert-example"  -d .
    Copy to Clipboard Toggle word wrap
  5. Run the certutil command with the options set to the values in the existing certificate. 
    certutil -d . -R -k "NSS Certificate DB:cert-pki-tomcat CA" -s "cn=CA Authority,o=Example Domain" -a -o example.req2.txt
    Copy to Clipboard Toggle word wrap
    The difference between generating a new certificate and key pair and renewing the certificate is the value of the -k option. To generate an entirely new request and key pair, then -k sets the key type and is used with -g, which sets the bit length. For a renewal request, the -k option uses the certificate nickname to access the existing key pair stored in the security database.
    For further details about the parameters, see the certutil(1) man page.
  6. Submit the certificate request and then retrieve it and install it.
Certificate System does not automatically renew its server certificates online while the PKI server is running. In general, administrators should renew the system certificates before they expire. However, if a system certificate expires, Certificate System will fail to start.
To renew system certificates after expiration, you can set up a temporary server certificate:
  1. If the system certificate is expired:
    1. Create a temporary certificate: 
      # pki-server cert-create sslserver --temp
      Copy to Clipboard Toggle word wrap
    2. Import the temporary certificate into Certificate System's Network Security Services (NSS) database: 
      # pki-server cert-import sslserver
      Copy to Clipboard Toggle word wrap
    3. Start Certificate System: 
      # systemctl start pki-tomcatd-nuxwdog@instance_name.service
      Copy to Clipboard Toggle word wrap
  2. Display the certificates and note the ID of the expired system certificate: 
    # pki-server cert-find
    Copy to Clipboard Toggle word wrap
  3. Create the new permanent certificate: 
    # pki-server cert-create certificate_ID
    Copy to Clipboard Toggle word wrap
  4. Stop Certificate System: 
    # systemctl stop pki-tomcatd-nuxwdog@instance_name.service
    Copy to Clipboard Toggle word wrap
  5. Import the new certificate to replace the expired certificate: 
    # pki-server cert-import certificate_ID
    Copy to Clipboard Toggle word wrap
  6. Start Certificate System: 
    # systemctl start pki-tomcatd-nuxwdog@instance_name.service
    Copy to Clipboard Toggle word wrap

14.3. Changing the Names of Subsystem Certificates
Copy link

One alternative to renewing certificates is replacing them with new certificates, meaning that a new certificate is generated with new keys. Generally, a new certificate can be added to the database and the old one deleted, a simple one-to-one swap. This is possible because the individual subsystem servers identify certificates based on their nickname; as long as the certificate nickname remains the same, the server can find the required certificate even if other factors — like the subject name, serial number, or key — are different.
These tables list all of the configuration parameters for each of the subsystem's certificates:

14.4. Managing the Certificate Database
Copy link

Each Certificate System instance has a certificate database, which is maintained in its internal token. This database contains certificates belonging to the subsystem installed in the Certificate System instance and various CA certificates the subsystems use for validating the certificates they receive.
Even if an external token is used to generate and store key pairs, Certificate System always maintains its list of trusted and untrusted CA certificates in its internal token.
This section explains how to view the contents of the certificate database, delete unwanted certificates, and change the trust settings of CA certificates installed in the database using the Certificate System window. For information on adding certificates to the database, see Section 14.4.1, “Installing Certificates in the Certificate System Database”.

Note

The Certificate System command-line utility certutil can be used to manage the certificate database by editing trust settings and adding and deleting certificates. For details about this tool, see http://www.mozilla.org/projects/security/pki/nss/tools/.
Administrators should periodically check the contents of the certificate database to make sure that it does not include any unwanted CA certificates. For example, if the database includes CA certificates that should not ever be trusted within the PKI setup, delete them.
If new server certificates are issued for a subsystem, they must be installed in that subsystem database. Additionally, user and agent certificates must be installed in the subsystem databases. If the certificates are issued by an external CA, then usually the corresponding CA certificate or certificate chain needs to be installed.
Certificates can be installed in the subsystem certificate database through the Console's Certificate Setup Wizard or using the certutil utility.
The Certificate Setup Wizard can install or import the following certificates into either an internal or external token used by the Certificate System instance:
  • Any of the certificates used by a Certificate System subsystem
  • Any trusted CA certificates from external CAs or other Certificate System CAs
  • Certificate chains
A certificate chain includes a collection of certificates: the subject certificate, the trusted root CA certificate, and any intermediate CA certificates needed to link the subject certificate to the trusted root. However, the certificate chain the wizard imports must include only CA certificates; none of the certificates can be a user certificate.
In a certificate chain, each certificate in the chain is encoded as a separate DER-encoded object. When the wizard imports a certificate chain, it imports these objects one after the other, all the way up the chain to the last certificate, which may or may not be the root CA certificate. If any of the certificates in the chain are already installed in the local certificate database, the wizard replaces the existing certificates with the ones in the chain. If the chain includes intermediate CA certificates, the wizard adds them to the certificate database as untrusted CA certificates.
The subsystem console uses the same wizard to install certificates and certificate chains. To install certificates in the local security database, do the following:
  1. Open the console. 
    pkiconsole https://server.example.com:secure_port/subsystem_type
    Copy to Clipboard Toggle word wrap
  2. In the Configuration tab, select System Keys and Certificates from the left navigation tree.
  3. There are two tabs where certificates can be installed, depending on the subsystem type and the type of certificate.
    • The CA Certificates tab is for installing CA certificates and certificate chains. For Certificate Managers, this tab is used for third-party CA certificates or other Certificate System CA certificates; all of the local CA certificates are installed in the Local Certificates tab. For all other subsystems, all CA certificates and chains are installed through this tab.
    • The Local Certificates tab is where all server certificates, subsystem certificates, and local certificates such as OCSP signing or KRA transport are installed.
    Select the appropriate tab.
  4. To install a certificate in the Local Certificates tab, click Add/Renew. To install a certificate in the CA Certificates tab, click Add. Both will open the Certificate Setup Wizard.
    1. When the wizard opens, select the Install a certificate radio button, and click Next.
    2. Select the type of certificate to install. The options for the drop-down menu are the same options available for creating a certificate, depending on the type of subsystem, with the additional option to install a cross-pair certificate.
    3. Paste in the certificate body, including the -----BEGIN CERTIFICATE----- and -----END CERTIFICATE-----, into the text area, or specify the absolute file location; this must be a local file.
      The certificate will look like the following: 
      -----BEGIN CERTIFICATE-----

-----END CERTIFICATE-----
      Copy to Clipboard Toggle word wrap
  5. The wizard displays the certificate details. Review the fingerprint to make sure this is the correct certificate, or use the Back button to go back and submit a different one. Give a nickname for the certificate.
    The wizard installs the certificate.
  6. Any CA that signed the certificate must be trusted by the subsystem. Make sure that this CA's certificate exists in the subsystem's certificate database (internal or external) and that it is trusted.
    If the CA certificate is not listed, add the certificate to the certificate database as a trusted CA. If the CA's certificate is listed but untrusted, change the trust setting to trusted, as shown in Section 14.5, “Changing the Trust Settings of a CA Certificate”.
    When installing a certificate issued by a CA that is not stored in the Certificate System certificate database, add that CA's certificate chain to the database. To add the CA chain to the database, copy the CA chain to a text file, start the wizard again, and install the CA chain.
14.4.1.2. Installing Certificates Using certutil
Copy link
To install subsystem certificates in the Certificate System instance's security databases using certutil, do the following:
  1. Open the subsystem's security database directory. 
    cd /var/lib/pki/instance_name/alias
    Copy to Clipboard Toggle word wrap
  2. Run the certutil command with the -A to add the certificate and -i pointing to the file containing the certificate issued by the CA. 
    certutil -A -n cert-name -t trustargs
   -d . -a -i certificate_file
    Copy to Clipboard Toggle word wrap

    Note

    If the Certificate System instance's certificates and keys are stored on an HSM, then specify the token name using the -h option.
    For example: 
    certutil -A -n "ServerCert cert-instance_name" -t u,u,u -d . -a -i /tmp/example.cert
    Copy to Clipboard Toggle word wrap
For information about using the certutil command, see http://www.mozilla.org/projects/security/pki/nss/tools/certutil.html.
14.4.1.3. About CA Certificate Chains
Copy link
Any client or server software that supports certificates maintains a collection of trusted CA certificates in its certificate database. These CA certificates determine which other certificates the software can validate. In the simplest case, the software can validate only certificates issued by one of the CAs for which it has a certificate. It is also possible for a trusted CA certificate to be part of a chain of CA certificates, each issued by the CA above it in a certificate hierarchy.
The first certificate in the chain is processed in a context-specific manner, which varies according to how it is being imported. For Mozilla Firefox, this handling depends upon the MIME content type used on the object being downloaded. For Red Hat servers, it depends upon the options selected in the server administration interface.
Subsequent certificates are all treated the same. If the certificates contain the TLS-CA bit in the Netscape Certificate Type certificate extension and do not already exist in the local certificate database, they are added as untrusted CAs. They can be used for certificate chain validation as long as there is a trusted CA somewhere in the chain.

14.4.2. Viewing Database Content
Copy link

The certificates stored in the subsystem certificates database, cert8.db, can be viewed through the subsystem administrative console. Alternatively, the certificates can be listed using the certutil utility. certutil must be used to view the TPS certificates because the TPS subsystem does not use an administrative console.

Note

The certificates listed in the cert8.db database are the subsystem certificates used for subsystem operations. User certificates are stored with the user entries in the LDAP internal database.
To view the contents of the database through the administrative console, do the following:
  1. Open the subsystem console. 
    pkiconsole https://server.example.com:secure_port/subsystem_type
    Copy to Clipboard Toggle word wrap
  2. In the Configuration tab, select System Keys and Certificates from the left navigation tree.
  3. There are two tabs, CA Certificates and Local Certificates, which list different kinds of certificates.
    • CA Certificates lists CA certificates for which the corresponding private key material is not available, such as certificates issued by third-party CAs such as Entrust or Verisign or external Certificate System Certificate Managers.
    • Local Certificates lists certificates kept by the Certificate System subsystem instance, such as the KRA transport certificate or OCSP signing certificate.

    Figure 14.1. Certificate Database Tab

  4. The Certificate Database Management table lists the all of the certificates installed on the subsystem. The following information is supplied for each certificate:
    • Certificate Name
    • Serial Number
    • Issuer Names, the common name (cn) of the issuer of this certificate.
    • Token Name, the name of the cryptographic token holding the certificate; for certificate stored in the database, this is internal.
To view more detailed information about the certificate, select the certificate, and click View. This opens a window which shows the serial number, validity period, subject name, issuer name, and certificate fingerprint of the certificate.
14.4.2.2. Viewing Database Content Using certutil
Copy link
To view the certificates in the subsystem database using certutil, open the instance's certificate database directory, and run the certutil with the -L option. For example: 
cd /var/lib/pki/instance_name/alias

certutil -L -d .

14.4.3. Deleting Certificates from the Database
Copy link

Removing unwanted certificates reduces the size of the certificate database.

Note

When deleting CA certificates from the certificate database, be careful not to delete the intermediate CA certificates, which help a subsystem chain up to the trusted CA certificate. If in doubt, leave the certificates in the database as untrusted CA certificates; see Section 14.5, “Changing the Trust Settings of a CA Certificate”.

For information about using the certutil command, see http://www.mozilla.org/projects/security/pki/nss/tools/certutil.html.
Certificate System subsystems use the CA certificates in their certificate databases to validate certificates received during a TLS-enabled communication.
It can be necessary to change the trust settings on a CA stored in the certificate database, temporarily or permanently. For example, if there is a problem with access or compromised certificates, marking the CA certificate as untrusted prevents entities with certificates signed by that CA from authenticating to the Certificate System. When the problem is resolved, the CA can be marked as trusted again.
To untrust a CA permanently, consider removing its certificate from the trust database. For instructions, see Section 14.4.3, “Deleting Certificates from the Database”.
To change the trust setting of a CA certificate, do the following:
  1. Open the subsystem console. 
    pkiconsole https://server.example.com:secure_port/subsystem_type
    Copy to Clipboard Toggle word wrap
  2. In the Configuration tab, System Keys and Certificates from the left navigation tree.
  3. Select the CA certificates tab.
  4. Select the CA certificate to modify, and click Edit.
  5. A prompt opens which reads The Certificate chain is (un)trusted, are you sure you want to (un)trust it?
    Clicking yes changes the trust setting of the certificate chain; pressing no preserves the original trust relationship.

14.5.2. Changing Trust Settings Using certutil

14.6. Managing Tokens Used by the Subsystems
Copy link

Note

Features in this section on TMS are not tested in the evaluation. This section is for reference only.
Certificate System managers two groups of tokens: tokens used by the subsystems to perform PKI tasks and tokens issued through the subsystem. These management tasks refer specifically to tokens that are used by the subsystems.

14.6.1. Detecting Tokens
Copy link

To see if a token can be detected by Certificate System to be installed or configured, use the TokenInfo utility. 
TokenInfo /var/lib/pki/instance_name/alias
Database Path: /var/lib/pki/instance_name/alias
Found external module 'NSS Internal PKCS #11 Module'
Copy to Clipboard Toggle word wrap
This utility will return all tokens which can be detected by the Certificate System, not only tokens which are installed in the Certificate System.

14.6.2. Viewing Tokens
Copy link

To view a list of the tokens currently installed for a Certificate System instance, use the modutil utility.
  1. Open the instance alias directory. For example: 
    cd /var/lib/pki/instance_name/alias
    Copy to Clipboard Toggle word wrap
  2. Show the information about the installed PKCS #11 modules installed as well as information on the corresponding tokens using the modutil tool. 
    modutil -dbdir . -nocertdb -list
    Copy to Clipboard Toggle word wrap

14.6.3. Changing a Token's Password
Copy link

The token, internal or external, that stores the key pairs and certificates for the subsystems is protected (encrypted) by a password. To decrypt the key pairs or to gain access to them, enter the token password. This password is set when the token is first accessed, usually during Certificate System installation.
It is good security practice to change the password that protects the server's keys and certificates periodically. Changing the password minimizes the risk of someone finding out the password. To change a token's password, use the certutil command-line utility.
For information about certutil, see http://www.mozilla.org/projects/security/pki/nss/tools/.
The single sign-on password cache stores token passwords in the password.conf file. This file must be manually updated every time the token password is changed.
The section contains how to set time and date in Red Hat Enterprise Linux 7.6.
The system time is always kept in Coordinated Universal Time (UTC) and converted in applications to local time as needed. Local time is the actual time in your current time zone, taking into account daylight saving time (DST).
The timedatectl utility is distributed as part of the systemd system and service manager and allows you to review and change the configuration of the system clock.

Changing the Current Time

timedatectl set-time HH:MM:SS
Copy to Clipboard Toggle word wrap
Replace HH with an hour, MM with a minute, and SS with a second, all typed in two-digit form.

Changing the Current Date

timedatectl set-time YYYY-MM-DD
Copy to Clipboard Toggle word wrap
Replace YYYY with a four-digit year, MM with a two-digit month, and DD with a two-digit day of the month.
The time change is audited by the operating system. For more information see 13.2.1.3. Auditing Time Change Events in Red Hat Certificate System's Planning, Installation, and Deployment Guide.
The Red Hat Certificate System product version is stored in the /usr/share/pki/CS_SERVER_VERSION file. To display the version: 
# cat /usr/share/pki/CS_SERVER_VERSION
Red Hat Certificate System 9.4 (Batch Update 3)
Copy to Clipboard Toggle word wrap
To find the product version of a running server, access the following URLs from your browser:
  • http://host_name:port_number/ca/admin/ca/getStatus
  • http://host_name:port_number/kra/admin/kra/getStatus
  • http://host_name:port_number/ocsp/admin/ocsp/getStatus
  • http://host_name:port_number/tks/admin/tks/getStatus
  • http://host_name:port_number/tps/admin/tps/getStatus

Note

Note that each component is a separate package and thus could have a separate version number. The above will show the version number for each currently running component.

Chapter 17. Updating Red Hat Certificate System
Copy link

To update Certificate System the operating system is running on, use the yum update command. This downloads, verifies, and installs updates to Certificate System and operating system packages. For further information on updating Certificate System and validating that the update was successful, see Updating Certificate System Packages section in the Red Hat Certificate System Planning, Installation, and Deployment Guide (Common Criteria Edition).

This chapter covers some of the more common usage problems that are encountered when installing Certificate System.
Q: The init script returned an OK status, but my CA instance does not respond. Why?
Q: I can't open the pkiconsole and I'm seeing Java exceptions in stdout.
Q: I tried to run pkiconsole, and I got Socket exceptions in stdout. Why?
Q: I tried to enroll for a certificate, and I got the error "request is not submitted...Subject Name Not Found"?
Q: Why are my enrolled certificates not being published?
Q: How do I open the pkiconsole utility from a remote host?
Q: What do I do when the LDAP server is not responding?
Q:
The init script returned an OK status, but my CA instance does not respond. Why?
A:
This should not happen. Usually (but not always), this indicates a listener problem with the CA, but it can have many different causes. Check in the catalina.out, system, and debug log files for the instance to see what errors have occurred. This lists a couple of common errors.
One situation is when there is a PID for the CA, indicating the process is running, but that no listeners have been opened for the server. This would return Java invocation class errors in the catalina.out file:

Q:
I can't open the pkiconsole and I'm seeing Java exceptions in stdout.
A:
This probably means that you have the wrong JRE installed or the wrong JRE set as the default. Run alternatives --config java to see what JRE is selected. Red Hat Certificate System requires OpenJDK 1.8.
Q:
I tried to run pkiconsole, and I got Socket exceptions in stdout. Why?
A:
This means that there is a port problem and usually means the wrong port was given to access the admin interface.
Port errors will look like the following:

Q:
I tried to enroll for a certificate, and I got the error "request is not submitted...Subject Name Not Found"?
A:
This most often occurs with a custom LDAP directory authentication profile and it shows that the directory operation failed. Particularly, it failed because it could not construct a working DN. The error will be in the CA's debug log. For example, this profile used a custom attribute (MYATTRIBUTE) that the directory didn't recognize: 
[14/Feb/2011:15:52:25][http-1244-Processor24]: BasicProfile: populate() policy
setid =userCertSet

15:52:25 PST 2011 id=caProfileSubmit time=13
Copy to Clipboard Toggle word wrap
Any custom components — attributes, object classes, and unregistered OIDs — which are used in the subject DN can cause a failure. For most cases, the X.509 attributes defined in RHC 2253 should be used in subject DNs instead of custom attributes.
Q:
Why are my enrolled certificates not being published?
A:
This usually indicates that the CA is misconfigured. The main place to look for errors is the debug log, which can indicate where the misconfiguration is. For example, this has a problem with the mappers: 
[31/Jul/2010:11:18:29][Thread-29]: LdapSimpleMap: cert subject
dn:UID=me,E=me@example.com,CN=yes
[31/Jul/2010:11:18:29][Thread-29]: Error mapping:

find a match in the LDAP server for certificate. netscape.ldap.LDAPException:
error result (32); matchedDN = ou=people,c=test; No such object
Copy to Clipboard Toggle word wrap
Check the publishing configuration in the Publishing tab of the CA console. In this example, the problem was in the mapping parameter, which must point to an existing LDAP suffix: 
ca.publish.mapper.instance.LdapUserCertMap.dnPattern=UID=$subj.UID,dc=publish
Copy to Clipboard Toggle word wrap
Q:
How do I open the pkiconsole utility from a remote host?
A:
In certain situations, administrators want to open the pkiconsole on the Certificate System server from a remote host. For that, administrators can use a Virtual Network Computing (VNC) connection:
  1. Setup a VNC server, for example, on the Red Hat Certificate System server.

    Important

    The pkiconsole utility cannot run on a server with Federal Information Processing Standard (FIPS) mode enabled. Use a different host with Red Hat Enterprise Linux to run the VNC server, if FIPS mode is enabled on your Certificate System server.
    For details about installing a VNC server, see the VNC Server section in the Red Hat System Administrator's Guide.
  2. Use a VNC viewer to connect to the host running the VNC server. For details, see the VNC Viewer section in the Red Hat System Administrator's Guide.
  3. Open the pkiconsole utility in the VNC window. For example: 
    # pkiconsole https://server.example.com:8443/ca
    Copy to Clipboard Toggle word wrap

Note

VNC viewers are available for different kind of operating systems. However, Red Hat supports only VNC viewers installed on Red Hat Enterprise Linux from the integrated repositories.
Q:
What do I do when the LDAP server is not responding?
A:
If the Red Hat Directory Server instance used for the internal database is not running, a connectivity issue occurred, or a TLS connection failure occurred, then you cannot connect to the subsystem instances which rely on it. The instance debug logs will specifically identify the problem with the LDAP connection. For example, if the LDAP server was not online: 
[02/Apr/2019:15:55:41][authorityMonitor]: authorityMonitor: failed to get LDAPConnection. Retrying in 1 second.
[02/Apr/2019:15:55:42][authorityMonitor]: In LdapBoundConnFactory::getConn()

It is important for administrators to periodically monitor possible failures, such as the following:
  • Audit failure caused by a full disk
  • Signing failure caused by HSM connection issue
  • LDAP server connection issues
  • And so on
Self-tests can also be run by demand as described in Chapter 10, Self Tests.

Part V. References
Copy link

Profile inputs and outputs define the expected input parameters in the certificate request and the output format of the enrollment result. Like many other components in Red Hat Certificate System, profile inputs and outputs are implemented as JAVA plug-ins to offer customization and flexibility. This appendix provides reference for the default input and output plug-ins.

A.1. Input Reference
Copy link

An input puts certain fields on the enrollment page associated with a particular certificate profile. The inputs set for a certificate profile are used to generate the enrollment page dynamically with the appropriate fields; these input fields collect necessary information for the profile to generate the final certificate.

A.1.1. CMC Certificate Request Input
Copy link

The CMC Certificate Request input is used for enrollments using a Certificate Message over CMS (CMC) certificate request is submitted in the request form. The request type must be either PKCS #10 or CRMF, and the only field is the Certificate Request text area in which to paste the request.

Example A.1. 

caCMCUserCert.cfg:input.i1.class_id=cmcCertReqInputImpl
Copy to Clipboard Toggle word wrap

A.1.2. nsHKeyCertRequest (Token Key) Input
Copy link

In Token Management Systems (TMS), the Token Key input is used to enroll keys for hardware tokens for agents to use later for certificate-based authentication.
This input puts the following fields into the enrollment form:
  • Token Key CUID. This field gives the CUID (contextually unique user ID) for the token device.
  • Token Key User Public Key. This field must contain the token user's public key.

Example A.2. 

caTempTokenDeviceKeyEnrollment.cfg:input.i1.class_id=nsHKeyCertReqInputImpl
Copy to Clipboard Toggle word wrap

A.1.3. nsNKeyCertRequest (Token User Key) Input
Copy link

In TMS, the Token User Key input is used to enroll keys for the user of a hardware token, for agents to use the token later for certificate-based authentication. This input puts the following fields into the enrollment form:
  • Token Key User UID. This field gives the UID for the LDAP entry of the user of the token device.
  • Token Key User Public Key. This field must contain the token user's public key.

Example A.3. 

caTempTokenUserEncryptionKeyEnrollment.cfg:input.i1.class_id=nsNKeyCertReqInputImpl
Copy to Clipboard Toggle word wrap

A.1.4. Subject DN Input
Copy link

In TMS, the Subject DN input allows the user to input the specific DN to set as the certificate subject name, and the input inserts a single Subject Name field into the enrollment form.

Example A.4. 

caAdminCert.cfg:input.i3.class_id=subjectDNInputImpl
Copy to Clipboard Toggle word wrap

A.1.5.  Subject Alternative Name Extension Input
Copy link

In TMS, the Subject Alternative Name Extension Input is used along with the Subject Alternative Name Extension Default plug-in. It allows admins to enable the numbered parameters in URI with the pattern req_san_pattern_# into the input and therefore the SubjectAltNameExt extension. For example, URI containing: 
...&req_san_pattern_0=host0.Example.com&req_san_pattern_1=host1.Example.com
Copy to Clipboard Toggle word wrap
injects host0.Example.com and host1.Example.com into the SubjectAltNameExt extension from the profile below.

A.2. Output Reference
Copy link

An output is the response to the end user of a successful enrollment.

A.2.1. CMC Certificate Output
Copy link

The profile framework enables you to specify output plug-ins. In case of certificate enrollments using CMC requests, the output is implicitly set to CMC output in conformance with RFC 5272. Therefore, the output value specified in the profile is ignored.

A.2.2. nsNSKeyOutput
Copy link

In TMS, this class implements the output plug-in that returns the DER encoded certificates for token keys.

Example A.6. caTokenUserDelegateAuthKeyEnrollment.cfg

This appendix explains both the standard certificate extensions defined by X.509 v3 and the extensions defined by Netscape that were used in versions of products released before X.509 v3 was finalized. It provides recommendations for extensions to use with specific kinds of certificates, including PKIX Part 1 recommendations.

Important

This appendix is a reference for defaults, constraints, and certificate and CRL extensions that are used or are configurable in Red Hat Certificate System. For a complete reference and explanation of certificate and CRL extensions, see RFC 5280.
This appendix contains the following sections:

B.1. Defaults Reference
Copy link

Defaults are used to define the contents of a certificate. This section lists and defines the predefined defaults.

B.1.1. Authority Info Access Extension Default
Copy link

This default attaches the Authority Info Access extension. This extension specifies how an application validating a certificate can access information, such as online validation services and CA policy data, about the CA that has issued the certificate. This extension should not be used to point directly to the CRL location maintained by a CA; the CRL Distribution Points extension, Section B.1.8, “CRL Distribution Points Extension Default”, provides references to CRL locations.
For general information about this extension, see Section B.3.1, “authorityInfoAccess”.
The following constraints can be defined with this default:
This default can define up to five locations, with parameters for each location. The parameters are marked with an n in the table to show with which location the parameter is associated.
Expand
Table B.1. Authority Info Access Extension Default Configuration Parameters
Parameter Description
Critical Select true to mark this extension critical; select false to mark the extension noncritical.
Method_n
Specifies the access method for retrieving additional information about the CA that has issued the certificate in which the extension appears. This is one of the following values:
  • ocsp (1.3.6.1.5.5.7.48.1).
  • caIssuers (1.3.6.1.5.5.7.48.2)
  • renewal (2.16.840.1.113730.16.1)
LocationType_n Specifies the general name type for the location that contains additional information about the CA that has issued the certificate. This is one of the following types:
  • DirectoryName
  • DNSName
  • EDIPartyName
  • IPAddress
  • OID
  • RFC822Name
  • URIName
Location_n
Specifies the address or location to get additional information about the CA that has issued the certificate.
  • For directoryName, the value must be a string form of X.500 name, similar to the subject name in a certificate. For example, cn=SubCA, ou=Research Dept, o=Example Corporation, c=US.
  • For dNSName, the value must be a valid fully-qualified domain name. For example, testCA.example.com.
  • For EDIPartyName, the value must be an IA5String. For example, Example Corporation.
  • For iPAddress, the value must be a valid IP address. An IPv4 address must be in the format n.n.n.n or n.n.n.n,m.m.m.m. For example, 128.21.39.40 or 128.21.39.40,255.255.255.00. An IPv6 address uses a 128-bit namespace, with the IPv6 address separated by colons and the netmask separated by periods. For example, 0:0:0:0:0:0:13.1.68.3, FF01::43, 0:0:0:0:0:0:13.1.68.3,FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:255.255.255.0, and FF01::43,FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FF00:0000.
  • For OID, the value must be a unique, valid OID specified in dot-separated numeric component notation. For example, 1.2.3.4.55.6.5.99.
  • For RFC822Name, the value must be a valid Internet mail address.
  • For URIName, the value must be a non-relative universal resource identifier (URI) following the URL syntax and encoding rules. The name must include both a scheme, such as http, and a fully-qualified domain name or IP address of the host. For example, http://ocspResponder.example.com:8000. Certificate System allows both IPv4 and IPv6 IP addresses.
Enable_n Specifies whether this location is enabled. Select true to mark this as set; select false to disable it.

This default attaches the Authority Key Identifier extension to the certificate. The extension identifies the public key that corresponds to the private key used by a CA to sign certificates. This default has no parameters. If used, this extension is included in the certificate with the public key information.
This default takes the following constraint:
For general information about this extension, see Section B.3.2, “authorityKeyIdentifier”.

B.1.3. Authentication Token Subject Name Default
Copy link

This profile default populates subject names based on the attribute values in the authentication token (AuthToken) object.
This default plug-in works with the directory-based authentication manager, SharedToken.
In addition, the directory-based authentication manager formulates the subject name of the issuing certificate. It forms the subject name by using the user's DN value from AuthToken.
This default is responsible for reading the subject name from the AuthToken and placing it in the certificate request so that the final certificate contains the subject name.
The following constraints can be defined with this default:

B.1.4. CMC User-signed Subject Name Default
Copy link

This profile default populates subject names based on the CMC request signer's subjectDN. The following constraint must be used with this default:

B.1.5. Basic Constraints Extension Default
Copy link

This default attaches the Basic Constraint extension to the certificate. The extension identifies whether the Certificate Manager is a CA. The extension is also used during the certificate chain verification process to identify CA certificates and to apply certificate chain-path length constraints.
For general information about this extension, see Section B.3.3, “basicConstraints”.
The following constraints can be defined with this default:
Expand
Table B.2. Basic Constraints Extension Default Configuration Parameters
Parameter Description
Critical Select true to mark this extension critical; select false to mark the extension noncritical.
IsCA Specifies whether the certificate subject is a CA. With true, the server checks the PathLen parameter and sets the specified path length in the certificate. With false, the server treats the certificate subject as a non-CA and ignores the value specified for the PathLen parameter.
PathLen
Specifies the path length, the maximum number of CA certificates that may be chained below (subordinate to) the subordinate CA certificate being issued. The path length affects the number of CA certificates to be used during certificate validation. The chain starts with the end-entity certificate being validated and moves up.
The maxPathLen parameter has no effect if the extension is set in end-entity certificates.
The permissible values are 0 or n. The value should be less than the path length specified in the Basic Constraints extension of the CA signing certificate. 0 specifies that no subordinate CA certificates are allowed below the subordinate CA certificate; only an end-entity certificate may follow in the path. n must be an integer greater than zero. It specifies the maximum number of subordinate CA certificates allowed below the subordinate CA certificate.
If the field is blank, the path length defaults to a value that is determined by the path length set in the Basic Constraints extension in the issuer's certificate. If the issuer's path length is unlimited, the path length in the subordinate CA certificate will also be unlimited. If the issuer's path length is an integer greater than zero, the path length in the subordinate CA certificate will be set to a value that is one less than the issuer's path length; for example, if the issuer's path length is 4, the path length in the subordinate CA certificate will be set to 3.

B.1.6. CA Validity Default
Copy link

This default adds an option to a CA certificate enrollment or renewal profile to bypass the CA's signing certificate's expiration constraint. This means that the issued CA certificate can have an expiration date that is later than the issuing CA signing certificate expiration date.
The following constraints can be defined with this default:
Expand
Table B.3. CA Validity Default Parameters
Parameter Description
bypassCAnotafterrange Sets the default value for whether a requesting CA can request a certificate whose validity period extends past the issuing CA's validity period.

  • n must be an integer that is greater than zero. It specifies at the maximum number of subordinate CA certificates allowed in the path before policy mapping is no longer permitted. For example, a value of 1 indicates that policy mapping may be processed in certificates issued by the subject of this certificate, but not in additional certificates in the path.

B.1.21. Policy Mappers Extension Default
Copy link

This default attaches a Policy Mappings extension to the certificate. The extension lists pairs of OIDs, each pair identifying two policy statements of two CAs. The pairing indicates that the corresponding policies of one CA are equivalent to policies of another CA. The extension may be useful in the context of cross-certification. If supported, the extension is included in CA certificates only. The default maps policy statements of one CA to that of another by pairing the OIDs assigned to their policy statements
Each pair is defined by two parameters, issuerDomainPolicy and subjectDomainPolicy. The pairing indicates that the issuing CA considers the issuerDomainPolicy equivalent to the subjectDomainPolicy of the subject CA. The issuing CA's users may accept an issuerDomainPolicy for certain applications. The policy mapping tells these users which policies associated with the subject CA are equivalent to the policy they accept.
For general information about this extension, see Section B.3.12, “policyMappings”.
The following constraints can be defined with this default:

Table B.17. Policy Mappings Extension Default Configuration Parameters
Parameter Description
Critical Select true to mark this extension critical; select false to mark the extension noncritical.
IssuerDomainPolicy_n Specifies the OID assigned to the policy statement of the issuing CA to map with the policy statement of another CA. For example, 1.2.3.4.5.
SubjectDomainPolicy_n Specifies the OID assigned to the policy statement of the subject CA that corresponds to the policy statement of the issuing CA. For example, 6.7.8.9.10.

B.1.22. Private Key Usage Period Extension Default
Copy link

The Private Key Usage Period extension allows the certificate issuer to specify a different validity period for the private key than for the certificate itself. This extension is intended for use with digital signature keys.
Expand
Table B.18. Private key Usage Period Configuration Parameters
Parameter Description
Critical This extension should always be non-critical.
puStartTime This parameters sets the start time. The default value is 0, which starts the validity period from the time the extension is activated.
puDurationDays This parameters sets the duration of the usage period. The default value is 365, which sets the validity period to 365 days from the time the extension is activated.

B.1.23. Signing Algorithm Default
Copy link

This default attaches a signing algorithm in the certificate request. This default presents an agent with the possible algorithms that can be used for signing the certificate.
The following constraints can be defined with this default:
Expand
Table B.19. Signing Algorithm Default Configuration Parameters
Parameter Description
signingAlg Specify the default signing algorithm to be used to create this certificate. An agent can override this value by specifying one of the values contained in the signingAlgsAllowed parameter.
signingAlgsAllowed Specify the signing algorithms that can be used for signing this certificate. The algorithms can be any or all of the following:
  • SHA256withRSA
  • SHA384withRSA
  • SHA512withRSA
  • SHA256withEC
  • SHA384withEC
  • SHA512withEC

B.1.24. Subject Alternative Name Extension Default
Copy link

This default attaches a Subject Alternative Name extension to the certificate. The extension binds additional identities, such as an email address, a DNS name, an IP address (both IPv4 and IPv6), or a URI, to the subject of the certificate. The standard requires that if the certificate subject field contains an empty sequence, then the Subject Alternative name extension must contain the subject's alternative name and that the extension be marked critical.
For any of the directory-based authentication methods, the Certificate System can retrieve values for any string and byte attributes and set them in the certificate request. These attributes are set by entering them in the ldapStringAttributes and ldapByteAttributes fields defined in the automated enrollment modules.
If authenticated attributes — meaning attributes stored in an LDAP database — need to be part of this extension, use values from the $request.X$ token.
There is an additional attribute to insert a universally unique identifier (UUID) into the subject alt name. This option generates a random number for version 4 UUID; the pattern is defined by referencing the server which will generate the number in an additional subjAltExtSource parameter.
A basic Subject Alternative Name Extension default is configured in the example.

The Subject Alternative Name extension default checks the certificate request for the profile attributes. If the request contains an attribute, the profile reads its value and sets it in the extension. It is also possible for the Subject Alternative Name extension default to insert attribute values from an LDAP directory, if LDAP-based authentication is configured. The extension added to the certificates contain all the configured attributes.
The variables that can be used with the Subject Alternative Name extension default are listed in Table B.20, “Variables to Insert Values in the Subject Alternative Name”.

Multiple attributes can be set for a single extension. The subjAltNameNumGNs parameter controls how many of the listed attributes are required to be added to the certificate. This parameter must be added to custom profiles and may need modified in default profiles to include as many attributes as required. In Example B.1, “Default Subject Alternative Name Extension Configuration”, the subjAltNameNumGNs is set to 3 to insert the RFC822Name, DNSName, and URIName names (generic names _0, _1, and _2).
The following constraints can be defined with this default:
Expand
Table B.21. Subject Alternative Name Extension Default Configuration Parameters
Parameter Description
Critical Select true to mark this extension critical; select false to mark the extension noncritical.
Pattern Specifies the request attribute value to include in the extension. The attribute value must conform to any of the supported general name types. If the server finds the attribute in the request, it sets the attribute value in the extension and adds the extension to certificates. If multiple attributes are specified and none of the attributes are present in the request, the server does not add the Subject Alternative Name extension to certificates. The permissible value is a request attribute included in the certificate request. For example, $request.requester_email$.
Type
Specifies the general name type for the request attribute.
  • Select RFC822Name if the request-attribute value is an email address in the local-part@domain format. For example, jdoe@example.com
  • Select DirectoryName if the request-attribute value is an X.500 directory name, similar to the subject name in a certificate. For example, cn=Jane Doe, ou=Sales Dept, o=Example Corporation, c=US.
  • Select DNSName if the request-attribute value is a DNS name. For example, corpDirectory.example.com.
  • Select EDIPartyName if the request-attribute value is an EDI party name. For example, Example Corporation.
  • Select URIName if the request-attribute value is a non-relative URI that includes both a scheme, such as http, and a fully qualified domain name or IP address of the host. For example, http://hr.example.com. Certificate System supports both IPv4 and IPv6 addresses.
  • Select IPAddress if the request-attribute value is a valid IP address specified in dot-separated numeric component notation. For example, 128.21.39.40. An IPv4 address must be in the format n.n.n.n or n.n.n.n,m.m.m.m. For example, 128.21.39.40 or 128.21.39.40,255.255.255.00. An IPv6 address uses a 128-bit namespace, with the IPv6 address separated by colons and the netmask separated by periods. For example, 0:0:0:0:0:0:13.1.68.3, FF01::43, 0:0:0:0:0:0:13.1.68.3,FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:255.255.255.0, and FF01::43,FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FF00:0000.
  • Select OIDName if the request-attribute value is a unique, valid OID specified in the dot-separated numeric component notation. For example, 1.2.3.4.55.6.5.99.
  • Select OtherName for names with any other format. This supports PrintableString, IA5String, UTF8String, BMPString, Any, and KerberosName. KerberosName has the format Realm|NameType|NameStrings, such as realm1|0|userID1,userID2.
    OtherName must have the format (type)oid,string. For example, (IA5String)1.2.3.4,MyExample.
Source Specifies an identification source or protocol to use to generate an ID. The only supported source is UUID4, which generates a random number to create the UUID.
Number of Components (NumGNs) Specifies the number of name components that must be included in the subject alternative name.
This default attaches a Subject Directory Attributes extension to the certificate. The Subject Directory Attributes extension conveys any desired directory attribute values for the subject of the certificate.
The following constraints can be defined with this default:

Table B.22. Subject Directory Attributes Extension Default Configuration Parameters
Parameter Description
Critical Select true to mark this extension critical; select false to mark the extension noncritical.
Name The attribute name; this can be any LDAP directory attribute, such as cn or mail.
Pattern Specifies the request attribute value to include in the extension. The attribute value must conform to the allowed values of the attribute. If the server finds the attribute, it sets the attribute value in the extension and adds the extension to certificates. If multiple attributes are specified and none of the attributes are present in the request, the server does not add the Subject Directory Attributes extension to certificates. For example, $request.requester_email$.
Enable Sets whether that attribute is able to be added to the certificate. Select true to enable the attribute.

B.1.26. Subject Info Access Extension Default
Copy link

Implements an enrollment default policy that populates a Subject Information Access extension in the certificate template. This extension indicates how to access information and services for the subject of the certificate in which the extension appears.
Expand
Parameter Description
Critical This extension is supposed to be non-critical.
subjInfoAccessNumADs The number of information access sections included with the certificate.
subjInfoAccessADMethod_n OID of the access method.
subjInfoAccessADMethod_n Type of access method.

i.e., a URL for URI Name.
subjInfoAccessADEnable_n Select true to enable this extension; select false to disable this extension.

B.1.27. Subject Key Identifier Extension Default
Copy link

This default attaches a Subject Key Identifier extension to the certificate. The extension identifies certificates that contain a particular public key, which identifies a certificate from among several that have the same subject name.
For general information about this extension, see Section B.3.16, “subjectKeyIdentifier”.
If enabled, the profile adds a Subject Key Identifier Extension to an enrollment request if the extension does not already exist. If the extension exists in the request, such as a CRMF request, the default replaces the extension. After an agent approves the manual enrollment request, the profile accepts any Subject Key Identifier Extension that is already there.
This default has no parameters. If used, this extension is included in the certificate with the public key information.
The following constraints can be defined with this default:

B.1.28. Subject Name Default
Copy link

This default attaches a server-side configurable subject name to the certificate request. A static subject name is used as the subject name in the certificate.
The following constraints can be defined with this default:

B.1.29. User Key Default
Copy link

This default attaches a user-supplied key into the certificate request. This is a required default. Keys are part of the enrollment request.
The following constraints can be defined with this default:

B.1.30. User Signing Algorithm Default
Copy link

This default implements an enrollment default profile that populates a user-supplied signing algorithm in the certificate request. If included in the certificate profile, this allows a user to choose a signing algorithm for the certificate, subject to the constraint set.
No inputs are provided to add signing algorithm choices to the enrollment form, but it is possible to submit a request that contains this information.
The following constraints can be defined with this default:

B.1.31. User Subject Name Default
Copy link

This default attaches a user-supplied subject name to the certificate request. If included in the certificate profile, it allows a user to supply a subject name for the certificate, subject to the constraints set. This extension preserves the subject name that is specified in the original certificate request when the certificate is issued.
The following constraints can be defined with this default:

B.1.32. User Validity Default
Copy link

This default attaches a user-supplied validity to the certificate request. If included in the certificate profile, it allows a user to supply the validity period, subject to the constraints set. This default profile preserves that user-defined validity period in the original certificate request when the certificate is issued.
No inputs are provided to add user-supplied validity date to the enrollment form, but it is possible to submit a request that contains this information.
The following constraints can be defined with this default:

B.1.33. User Supplied Extension Default
Copy link

The User Supplied Extension Default class populates a certificate with any certificate extension defined by the user in the certificate request. This requires users to submit certificate requests which meet certain standards or give certain information because the profile can require specific extensions before enrolling a certificate.

Warning

Be exceptionally cautious about setting this extension default, since it allows users to specify an extension in the certificate request. If this default is used, then Red Hat strongly recommends using a constraint corresponding to the extension to minimize any possible abuse of the User Supplied Extension Default.
The user-defined extension is validated against whatever constraint is set, so it is possible to restrict the kind of extension (through the Extension Constraint) or to set rules for the key and other basic constraints, such as whether this is a CA certificate.
The CA handles an enrollment with the User Supplied Extension Default in one of three ways:
  • If the OID of the extension is specified in both the certificate request and the default, then the extension is validated by the constraints and applied to the certificate.
  • If an OID of an extension is given in the request but is not specified in the User Supplied Extension Default in the profile, then the user-specified extension is ignored, and the certificate is successfully enrolled without that extension.
  • If this extension is set on a profile with a corresponding OID (Extension Constraint), then any certificate request processed through that profile must carry the specified extension or the request is rejected.
A certificate request that contains the user-defined extensions must be submitted to the profile. The certificate enrollment forms, however, do not have any input fields for users to add user-supplied extensions. Submitting a certificate request without supplying the extension fails.
Example B.2, “User Supplied Extension Default for the Extended Key Usage Extension” adds the User Supplied Extension Default to a profile with the Extended Key Usage Constraint. The OID specified in the userExtOID parameter is for the Extended Key Usage Extension.

Example B.2. User Supplied Extension Default for the Extended Key Usage Extension

policyset.set1.2.constraint.class_id=extendedKeyUsageExtConstraintImpl
policyset.set1.2.constraint.name=Extended Key Usage Extension
policyset.set1.2.constraint.params.exKeyUsageCritical=false
policyset.set1.2.constraint.params.exKeyUsageOIDs=1.3.6.1.5.5.7.3.2,1.3.6.1.5.5.7.3.4
policyset.set1.2.default.class_id=userExtensionDefaultImpl
policyset.set1.2.default.name=User Supplied Extension Default
policyset.set1.2.default.params.userExtOID=2.5.29.37
Copy to Clipboard Toggle word wrap
In Example B.2, “User Supplied Extension Default for the Extended Key Usage Extension”, although the User Supplied Extension Default allows a user to specify the Extended Key Usage Extension (2.5.29.37), the constraint limits the user request to only the TLS client authentication (1.3.6.1.5.5.7.3.2) and email protection (1.3.6.1.5.5.7.3.4) uses.
Editing profiles is described in the section called Creating and Editing Certificate Profiles Directly on the File System in Red Hat Certificate System Planning, Installation and Deployment Guide.

Example B.3. Multiple User Supplied Extensions in CSR

The RHCS enrollment profile framework allows to define multiple User Supplied Extensions in the same profile. For example, a combination of the following can be specified.
  • For Extended Key Usage Extension: 
    policyset.serverCertSet.2.constraint.class_id=extendedKeyUsageExtConstraintImpl
policyset.serverCertSet.2.constraint.name=Extended Key Usage Extension
policyset.serverCertSet.2.constraint.params.exKeyUsageCritical=false
policyset.serverCertSet.2.constraint.params.exKeyUsageOIDs=1.3.6.1.5.5.7.3.2,1.3.6.1.5.5.7.3.4
policyset.serverCertSet.2.default.class_id=userExtensionDefaultImpl
policyset.serverCertSet.2.default.name=User Supplied Extension Default
policyset.serverCertSet.2.default.params.userExtOID=2.5.29.37

  • For Key Usage Extension:
    By using the following format, you can apply a policy which parameter of the extension:
    • Must exist in the CSR: value = "true"
    • Must not exist in the CSR: value = "false"
    • Is optional: value = "-"
    For example:

Constraints are used to define the allowable contents of a certificate and the values associated with that content. This section lists the predefined constraints with complete definitions of each.

B.2.1. Basic Constraints Extension Constraint
Copy link

The Basic Constraints extension constraint checks if the basic constraint in the certificate request satisfies the criteria set in this constraint.
Expand
Table B.25. Basic Constraints Extension Constraint Configuration Parameters
Parameter Description
basicConstraintsCritical Specifies whether the extension can be marked critical or noncritical. Select true to mark this extension critical; select false to prevent this extension from being marked critical. Selecting a hyphen -, implies no criticality preference.
basicConstraintsIsCA Specifies whether the certificate subject is a CA. Select true to require a value of true for this parameter (is a CA); select false to disallow a value of true for this parameter; select a hyphen, -, to indicate no constraints are placed for this parameter.
basicConstraintsMinPathLen
Specifies the minimum allowable path length, the maximum number of CA certificates that may be chained below (subordinate to) the subordinate CA certificate being issued. The path length affects the number of CA certificates used during certificate validation. The chain starts with the end-entity certificate being validated and moves up.
This parameter has no effect if the extension is set in end-entity certificates.
The permissible values are 0 or n. The value must be less than the path length specified in the Basic Constraints extension of the CA signing certificate.
0 specifies that no subordinate CA certificates are allowed below the subordinate CA certificate being issued; only an end-entity certificate may follow in the path.
n must be an integer greater than zero. This is the minimun number of subordinate CA certificates allowed below the subordinate CA certificate being used.
basicConstraintsMaxPathLen
Specifies the maximum allowable path length, the maximum number of CA certificates that may be chained below (subordinate to) the subordinate CA certificate being issued. The path length affects the number of CA certificates used during certificate validation. The chain starts with the end-entity certificate being validated and moves up.
This parameter has no effect if the extension is set in end-entity certificates.
The permissible values are 0 or n. The value must be greater than the path length specified in the Basic Constraints extension of the CA signing certificate.
0 specifies that no subordinate CA certificates are allowed below the subordinate CA certificate being issued; only an end-entity certificate may follow in the path.
n must be an integer greater than zero. This is the maximum number of subordinate CA certificates allowed below the subordinate CA certificate being used.
If the field is blank, the path length defaults to a value determined by the path length set on the Basic Constraints extension in the issuer's certificate. If the issuer's path length is unlimited, the path length in the subordinate CA certificate is also unlimited. If the issuer's path length is an integer greater than zero, the path length in the subordinate CA certificate is set to a value one less than the issuer's path length; for example, if the issuer's path length is 4, the path length in the subordinate CA certificate is set to 3.

B.2.2. CA Validity Constraint
Copy link

The CA Validity constraint checks if the validity period in the certificate template is within the CA's validity period. If the validity period of the certificate is out outside the CA certificate's validity period, the constraint is rejected.

B.2.3. Extended Key Usage Extension Constraint
Copy link

The Extended Key Usage extension constraint checks if the Extended Key Usage extension on the certificate satisfies the criteria set in this constraint.

Using this bit is controversial. Carefully consider the legal consequences of its use before setting it for any certificate.
keyEncipherment Specifies whether to set the extension for TLS server certificates and S/MIME encryption certificates. Select true to mark this as set; select false to keep this from being set; select a hyphen, -, to indicate no constraints are placed for this parameter.
keyUsageDataEncipherment Specifies whether to set the extension when the subject's public key is used to encrypt user data, instead of key material. Select true to mark this as set; select false to keep this from being set; select a hyphen, -, to indicate no constraints are placed for this parameter.
keyUsageKeyAgreement Specifies whether to set the extension whenever the subject's public key is used for key agreement. Select true to mark this as set; select false to keep this from being set; select a hyphen, -, to indicate no constraints are placed for this parameter.
keyUsageCertsign Specifies whether the extension applies for all CA signing certificates. Select true to mark this as set; select false to keep this from being set; select a hyphen, -, to indicate no constraints are placed for this parameter.
keyUsageCRLSign Specifies whether to set the extension for CA signing certificates that are used to sign CRLs. Select true to mark this as set; select false to keep this from being set; select a hyphen, -, to indicate no constraints are placed for this parameter.
keyUsageEncipherOnly Specifies whether to set the extension if the public key is to be used only for encrypting data. If this bit is set, keyUsageKeyAgreement should also be set. Select true to mark this as set; select false to keep this from being set; select a hyphen, -, to indicate no constraints are placed for this parameter.
keyUsageDecipherOnly Specifies whether to set the extension if the public key is to be used only for deciphering data. If this bit is set, keyUsageKeyAgreement should also be set. Select true to mark this as set; select false to keep this from being set; select a hyphen, -, to indicate no constraints are placed for this parameter.

Warning

This constraint is obsolete. Instead of using the Netscape Certificate Type extension constraint, use the Key Usage extension or Extended Key Usage extension.
The Netscape Certificate Type extension constraint checks if the Netscape Certificate Type extension in the certificate request satisfies the criteria set in this constraint.

B.2.8. No Constraint
Copy link

This constraint implements no constraint. When chosen along with a default, there are not constraints placed on that default.

B.2.9. Renewal Grace Period Constraint
Copy link

The Renewal Grace Period Constraint sets rules on when a user can renew a certificate based on its expiration date. For example, users cannot renew a certificate until a certain time before it expires or if it goes past a certain time after its expiration date.
One important thing to remember when using this constraint is that this constraint is set on the original enrollment profile, not the renewal profile. The rules for the renewal grace period are part of the original certificate and are carried over and applied for any subsequent renewals.
This constraint is only available with the No Default extension.
Expand
Table B.30. Renewal Grace Period Constraint Configuration Parameters
Parameter Description
renewal.graceAfter Sets the period, in days, after the certificate expires that it can be submitted for renewal. If the certificate has been expired longer that that time, then the renewal request is rejected. If no value is given, there is no limit.
renewal.graceBefore Sets the period, in days, before the certificate expires that it can be submitted for renewal. If the certificate is not that close to its expiration date, then the renewal request is rejected. If no value is given, there is no limit.

B.2.10. Signing Algorithm Constraint
Copy link

The Signing Algorithm constraint checks if the signing algorithm in the certificate request satisfies the criteria set in this constraint.
Expand
Table B.31. Signing Algorithms Constraint Configuration Parameters
Parameter Description
signingAlgsAllowed Sets the signing algorithms that can be specified to sign the certificate. The algorithms can be any or all of the following:
  • SHA256withRSA
  • SHA384withRSA
  • SHA512withRSA
  • SHA256withEC
  • SHA384withEC
  • SHA512withEC

B.2.11. Subject Name Constraint
Copy link

The Subject Name constraint checks if the subject name in the certificate request satisfies the criteria.
Expand
Table B.32. Subject Name Constraint Configuration Parameters
Parameter Description
Pattern Specifies a regular expression or other string to build the subject DN.
Subject Names and Regular Expressions

The regular expression for the Subject Name Constraint is matched by the Java facility for matching regular expressions. The format for these regular expressions are listed in https://docs.oracle.com/javase/7/docs/api/java/util/regex/Pattern.html. This allows wildcards such as asterisks (*) to search for any number of the characters and periods (.) to search for any type character.

For example, if the pattern of the subject name constraint is set to uid=.*, the certificate profile framework checks if the subject name in the certificate request matches the pattern. A subject name like uid=user, o=Example, c=US satisfies the pattern uid=.*. The subject name cn=user, o=example,c=US does not satisfy the pattern. uid=.* means the subject name must begin with the uid attribute; the period-asterisk (.*) wildcards allow any type and number of characters to follow uid.
It is possible to require internal patterns, such as .*ou=Engineering.*, which requires the ou=Engineering attribute with any kind of string before and after it. This matches cn=jdoe,ou=internal,ou=west coast,ou=engineering,o="Example Corp",st=NC as well as uid=bjensen,ou=engineering,dc=example,dc=com.
Lastly, it is also possible to allow requests that are either one string or another by setting a pipe sign (|) between the options. For example, to permit subject names that contain either ou=engineering,ou=people or ou=engineering,o="Example Corp", the pattern is .*ou=engineering,ou=people.* | .*ou=engineering,o="Example Corp".*.

Note

For constructing a pattern which uses a special character, such as a period (.), escape the character with a back slash (\). For example, to search for the string o="Example Inc.", set the pattern to o="Example Inc\.".
Subject Names and the UID or CN in the Certificate Request

The pattern that is used to build the subject DN can also be based on the CN or UID of the person requesting the certificate. The Subject Name Constraint sets the patter of the CN (or UID) to recognize in the DN of the certificate request, and then the Subject Name Default builds on that CN to create the subject DN of the certificate, using a predefined directory tree.

For example, to use the CN of the certificate request: 
policyset.serverCertSet.1.constraint.class_id=subjectNameConstraintImpl
policyset.serverCertSet.1.constraint.name=Subject Name Constraint
policyset.serverCertSet.1.constraint.params.pattern=CN=[^,]+,.+
policyset.serverCertSet.1.constraint.params.accept=true
policyset.serverCertSet.1.default.class_id=subjectNameDefaultImpl
policyset.serverCertSet.1.default.name=Subject Name Default
policyset.serverCertSet.1.default.params.name=CN=$request.req_subject_name.cn$,DC=example, DC=com

B.2.12. Unique Key Constraint
Copy link

This constraint checks that the public key is unique.
Expand
Table B.33. Unique Key Constraints Parameters
Parameter Description
allowSameKeyRenewal
A request is considered a renewal and is accepted if this parameter is set to true, if a public key is not unique, and if the subject DN matches an existing certificate. However, if the public key is a duplicate and does not match an existing Subject DN, the request is rejected.
When the parameter is set to false, a duplicate public key request will be rejected.

B.2.13. Unique Subject Name Constraint
Copy link

The Unique Subject Name constraint restricts the server from issuing multiple certificates with the same subject names. When a certificate request is submitted, the server automatically checks the nickname against other issued certificate nicknames. This constraint can be applied to certificate enrollment and renewal through the end-entities' page.
Certificates cannot have the same subject name unless one certificate is expired or revoked (and not on hold). So, active certificates cannot share a subject name, with one exception: if certificates have different key usage bits, then they can share the same subject name, because they have different uses.
Expand
Table B.34. Unique Subject Name Constraint Configuration Parameters
Parameter Description
enableKeyUsageExtensionChecking Optional setting which allows certificates to have the same subject name as long as their key usage settings are different. This is either true or false. The default is true, which allows duplicate subject names.

B.2.14. CMC User-signed Subject Name Constraint
Copy link

The CMC user-signed Subject Name Constraint restricts the certificates being issued to the user that signed the CMC request. Use it with CMCUserSignedSubjectNameDefault.

B.2.15. Validity Constraint
Copy link

The Validity constraint checks if the validity period in the certificate request satisfies the criteria.
The parameters provided must be sensible values. For instance, a notBefore parameter that provides a time which has already passed will not be accepted, and a notAfter parameter that provides a time earlier than the notBefore time will not be accepted.
Expand
Table B.35. Validity Constraint Configuration Parameters
Parameter Description
range The range of the validity period. This is an integer which sets the number of days. The difference (in days) between the notBefore time and the notAfter time must be less than the range value, or this constraint will be rejected.
notBeforeCheck Verifies that the range is not within the grace period. When the NotBeforeCheck Boolean parameter is set to true, the system will check the notBefore time is not greater than the current time plus the notBeforeGracePeriod value. If the notBeforeTime is not between the current time and the notBeforeGracePeriod value, this constraint will be rejected.
notBeforeGracePeriod The grace period (in seconds) after the notBefore time. If the notBeforeTime is not between the current time and the notBeforeGracePeriod value, this constraint will be rejected. This constraint is only checked if the notBeforeCheck parameter has been set to true.
notAfterCheck Verfies whether the given time is not after the expiration period. When the notAfterCheck Boolean parameter is set to true, the system will check the notAfter time is not greater than the current time. If the current time exceeds the notAfter time, this constraint will be rejected.
An X.509 v3 certificate contains an extension field that permits any number of additional fields to be added to the certificate. Certificate extensions provide a way of adding information such as alternative subject names and usage restrictions to certificates. Older Netscape servers, such as Red Hat Directory Server and Red Hat Certificate System, that were developed before PKIX part 1 standards were defined require Netscape-specific extensions.
The following is an example of the section of a certificate containing X.509 v3 extensions. The Certificate System can display certificates in readable pretty-print format, as shown here. As in this example, certificate extensions appear in sequence and only one instance of a particular extension may appear per certificate; for example, a certificate may contain only one subject key identifier extension. Certificates that support these extensions have the version 0x2 (which corresponds to version 3).

An object identifier (OID) is a string of numbers identifying a unique object, such as a certificate extension or a company's certificate practice statement. The Certificate System comes with a set of extension-specific profile plug-in modules which enable X.509 certificate extensions to be added to the certificates the server issues. Some of the extensions contain fields for specifying OIDs.
The PKIX standard recommends that all objects, such as extensions and statements, that are used in certificates be included in the form of an OID. This promotes interoperability between organizations on a shared network. If certificates will be issued that will be used on shared networks, register the OID prefixes with the appropriate registration authority.
OIDs are controlled by the International Standards Organization (ISO) registration authority. In some cases, this authority is delegated by ISO to regional registration authorities. In the United States, the American National Standards Institute (ANSI) manages this registration.
Using an OID registered to another organization or failing to register an OID may carry legal consequences, depending the situation. Registration may be subject to fees. For more information, contact the appropriate registration authority.
To define or assign OIDs for custom objects, know the company's arc, an OID for a private enterprise. If the company does not have an arc, it needs to get one. The http://www.alvestrand.no/objectid/ has more information on registering and using OIDs.
For example, the Netscape-defined OID for an extension named Netscape Certificate Comment is 2.16.840.1.113730.1.13. The OID assigned to this extension is hierarchical and includes the former Netscape company arc, 2.16.840.1. The OID definition entry is http://www.alvestrand.no/objectid/2.16.840.1.113730.1.13.html.
If an OID extension exists in a certificate and is marked critical, the application validating the certificate must be able to interpret the extension, including any optional qualifiers, or it must reject the certificate. Since it is unlikely that all applications will be able to interpret a company's custom extensions embedded in the form of OIDs, the PKIX standard recommends that the extension be always marked noncritical.
This section summarizes the extension types defined as part of the Internet X.509 version 3 standard and indicates which types are recommended by the PKIX working group.
This reference summarizes important information about each certificate. For complete details, see both the X.509 v3 standard, available from the ITU, and Internet X.509 Public Key Infrastructure - Certificate and CRL Profile (RFC 5280), available at RFC 5280. The descriptions of extensions reference the RFC and section number of the standard draft that discusses the extension; the object identifier (OID) for each extension is also provided.
Each extension in a certificate can be designated as critical or noncritical. A certificate-using system, such as a web browser, must reject the certificate if it encounters a critical extension it does not recognize; however, a noncritical extension can be ignored if it is not recognized.

B.3.1. authorityInfoAccess
Copy link

The Authority Information Access extension indicates how and where to access information about the issuer of the certificate. The extension contains an accessMethod and an accessLocation field. accessMethod specifies by OID the type and format of information about the issuer named in accessLocation.
PKIX Part 1 defines one accessMethod (id-ad-caIssuers) to get a list of CAs that have issued certificates higher in the CA chain than the issuer of the certificate using the extension. The accessLocation field then typically contains a URL indicating the location and protocol (LDAP, HTTP, or FTP) used to retrieve the list.
The Online Certificate Status Protocol (RFC 2560), available at RFC 2560, defines an accessMethod (id-ad-ocsp) for using OCSP to verify certificates. The accessLocation field then contains a URL indicating the location and protocol used to access an OCSP responder that can validate the certificate.
OID

1.3.6.1.5.5.7.1.1

Criticality

This extension must be noncritical.

B.3.2. authorityKeyIdentifier
Copy link

The Authority Key Identifier extension identifies the public key corresponding to the private key used to sign a certificate. This extension is useful when an issuer has multiple signing keys, such as when a CA certificate is renewed.
The extension consists of one or both of the following:
  • An explicit key identifier, set in the keyIdentifier field
  • An issuer, set in the authorityCertIssuer field, and serial number, set in the authorityCertSerialNumber field, identifying a certificate
If the keyIdentifier field exists, it is used to select the certificate with a matching subjectKeyIdentifier extension. If the authorityCertIssuer and authorityCertSerialNumber fields are present, then they are used to identify the correct certificate by issuer and serialNumber.
If this extension is not present, then the issuer name alone is used to identify the issuer certificate.
PKIX Part 1 requires this extension for all certificates except self-signed root CA certificates. Where a key identifier has not been established, PKIX recommends that the authorityCertIssuer and authorityCertSerialNumber fields be specified. These fields permit construction of a complete certificate chain by matching the SubjectName and CertificateSerialNumber fields in the issuer's certificate against the authortiyCertIssuer and authorityCertSerialNumber in the Authority Key Identifier extension of the subject certificate.
OID

2.5.29.35

Criticality

This extension is always noncritical and is always evaluated.

B.3.3. basicConstraints
Copy link

This extension is used during the certificate chain verification process to identify CA certificates and to apply certificate chain path length constraints. The cA component should be set to true for all CA certificates. PKIX recommends that this extension should not appear in end-entity certificates.
If the pathLenConstraint component is present, its value must be greater than the number of CA certificates that have been processed so far, starting with the end-entity certificate and moving up the chain. If pathLenConstraint is omitted, then all of the higher level CA certificates in the chain must not include this component when the extension is present.
OID

2.5.29.19

Criticality

PKIX Part 1 requires that this extension be marked critical. This extension is evaluated regardless of its criticality.

B.3.4. certificatePoliciesExt
Copy link

The Certificate Policies extension defines one or more policies, each of which consists of an OID and optional qualifiers. The extension can include a URI to the issuer's Certificate Practice Statement or can embed issuer information, such as a user notice in text form. This information can be used by certificate-enabled applications.
If this extension is present, PKIX Part 1 recommends that policies be identified with an OID only, or, if necessary, only certain recommended qualifiers.
OID

2.5.29.32

Criticality

This extension may be critical or noncritical.

B.3.5. CRLDistributionPoints
Copy link

This extension defines how CRL information is obtained. It should be used if the system is configured to use CRL issuing points.
If the extension contains a DistributionPointName with a type set to URI, the URI is assumed to be a pointer to the current CRL for the specified revocation reasons and will be issued by the named cRLIssuer. The expected values for the URI are those defined for the Subject Alternative Name extension. If the distributionPoint omits reasons, the CRL must include revocations for all reasons. If the distributionPoint omits cRLIssuer, the CRL must be issued by the CA that issued the certificate.
PKIX recommends that this extension be supported by CAs and applications.
OID

2.5.29.31

Criticality

PKIX recommends that this extension be marked noncritical and that it be supported for all certificates.

B.3.6. extKeyUsage
Copy link

The Extended Key Usage extension indicates the purposes for which the certified public key may be used. These purposes may be in addition to or in place of the basic purposes indicated in the Key Usage extension.

Important

Key Usage extension and Extended Key Usage extension consistency has to be maintained. For further details, see the Key Usage and Extended Key Usage Consistency section in the Red Hat Certificate System 9 Planning, Installation and Deployment Guide (Common Criteria Edition).
The Extended Key Usage extension must include OCSP Signing in an OCSP responder's certificate unless the CA signing key that signed the certificates validated by the responder is also the OCSP signing key. The OCSP responder's certificate must be issued directly by the CA that signs certificates the responder will validate.
The Key Usage, Extended Key Usage, and Basic Constraints extensions act together to define the purposes for which the certificate is intended to be used. Applications can use these extensions to disallow the use of a certificate in inappropriate contexts.
Table B.36, “PKIX Extended Key Usage Extension Uses” lists the uses defined by PKIX for this extension, and Table B.37, “Private Extended Key Usage Extension Uses” lists uses privately defined by Netscape.
OID

2.5.29.37

Criticality

If this extension is marked critical, the certificate must be used for one of the indicated purposes only. If it is not marked critical, it is treated as an advisory field that may be used to identify keys but does not restrict the use of the certificate to the indicated purposes.

OID

2.5.29.18

Criticality

PKIX Part 1 recommends that this extension be marked noncritical.

B.3.8. keyUsage
Copy link

The Key Usage extension defines the purpose of the key contained in the certificate. The Key Usage, Extended Key Usage, and Basic Constraints extensions act together to specify the purposes for which a certificate can be used.

Important

Key Usage extension and Extended Key Usage extension consistency has to be maintained. For further details, see the Key Usage and Extended Key Usage Consistency section in the Red Hat Certificate System 9 Planning, Installation and Deployment Guide (Common Criteria Edition).
If this extension is included at all, set the bits as follows:
  • digitalSignature (0) for TLS client certificates, S/MIME signing certificates, and object-signing certificates.
  • nonRepudiation (1) for some S/MIME signing certificates and object-signing certificates.

    Warning

    Use of this bit is controversial. Carefully consider the legal consequences of its use before setting it for any certificate.
  • keyEncipherment (2) for TLS server certificates and S/MIME encryption certificates.
  • dataEncipherment (3) when the subject's public key is used to encrypt user data instead of key material.
  • keyAgreement (4) when the subject's public key is used for key agreement.
  • keyCertSign (5) for all CA signing certificates.
  • cRLSign (6) for CA signing certificates that are used to sign CRLs.
  • encipherOnly (7) if the public key is used only for enciphering data. If this bit is set, keyAgreement should also be set.
  • decipherOnly (8) if the public key is used only for deciphering data. If this bit is set, keyAgreement should also be set.
Table B.38, “Certificate Uses and Corresponding Key Usage Bits” summarizes the guidelines for typical certificate uses.
If the keyUsage extension is present and marked critical, then it is used to enforce the usage of the certificate and key. The extension is used to limit the usage of a key; if the extension is not present or not critical, all types of usage are allowed.
If the keyUsage extension is present, critical or not, it is used to select from multiple certificates for a given operation. For example, it is used to distinguish separate signing and encryption certificates for users who have separate certificates and key pairs for operations.

B.3.9. nameConstraints
Copy link

This extension, which can used in CA certificates only, defines a name space within which all subject names in subsequent certificates in a certification path must be located.
OID

2.5.29.30

Criticality

PKIX Part 1 requires that this extension be marked critical.

B.3.10. OCSPNocheck
Copy link

The extension is meant to be included in an OCSP signing certificate. The extension tells an OCSP client that the signing certificate can be trusted without querying the OCSP responder (since the reply would again be signed by the OCSP responder, and the client would again request the validity status of the signing certificate). This extension is null-valued; its meaning is determined by its presence or absence.
Since the presence of this extension in a certificate will cause OCSP clients to trust responses signed with that certificate, use of this extension should be managed carefully. If the OCSP signing key is compromised, the entire process of validating certificates in the PKI will be compromised for the duration of the validity period of the certificate. Therefore, certificates using OCSPNocheck should be issued with short lifetimes and be renewed frequently.
OID

1.3.6.1.5.5.7.48.4

Criticality

This extension should be noncritical.

B.3.11. policyConstraints
Copy link

This extension, which is for CA certificates only, constrains path validation in two ways. It can be used to prohibit policy mapping or to require that each certificate in a path contain an acceptable policy identifier.
PKIX requires that, if present, this extension must never consist of a null sequence. At least one of the two available fields must be present.
OID

2.5.29.36

Criticality

This extension may be critical or noncritical.

B.3.12. policyMappings
Copy link

The Policy Mappings extension is used in CA certificates only. It lists one or more pairs of OIDs used to indicate that the corresponding policies of one CA are equivalent to policies of another CA. It may be useful in the context of cross-pair certificates.
This extension may be supported by CAs and applications.
OID

2.5.29.33

Criticality

This extension must be noncritical.

B.3.13. privateKeyUsagePeriod
Copy link

The Private Key Usage Period extension allows the certificate issuer to specify a different validity period for the private key than for the certificate itself. This extension is intended for use with digital signature keys.

Note

PKIX Part 1 recommends against the use of this extension. CAs conforming to PKIX Part 1 must not generate certificates with this extension.
OID

2.5.29.16

B.3.14. subjectAltName
Copy link

The Subject Alternative Name extension includes one or more alternative (non-X.500) names for the identity bound by the CA to the certified public key. It may be used in addition to the certificate's subject name or as a replacement for it. Defined name forms include Internet electronic mail address (SMTP, as defined in RFC-822), DNS name, IP address (both IPv4 and IPv6), and uniform resource identifier (URI).
PKIX requires this extension for entities identified by name forms other than the X.500 distinguished name (DN) used in the subject field. PKIX Part 1 describes additional rules for the relationship between this extension and the subject field.
Email addresses may be provided in the Subject Alternative Name extension, the certificate subject name field, or both. If the email address is part of the subject name, it must be in the form of the EmailAddress attribute defined by PKCS #9. Software that supports S/MIME must be able to read an email address from either the Subject Alternative Name extension or from the subject name field.
OID

2.5.29.17

Criticality

If the certificate's subject field is empty, this extension must be marked critical.

B.3.15. subjectDirectoryAttributes
Copy link

The Subject Directory Attributes extension conveys any desired directory attribute values for the subject of the certificate. It is not recommended as an essential part of the proposed PKIX standard but may be used in local environments.
OID

2.5.29.9

Criticality

PKIX Part 1 requires that this extension be marked noncritical.

B.3.16. subjectKeyIdentifier
Copy link

The Subject Key Identifier extension identifies the public key certified by this certificate. This extension provides a way of distinguishing public keys if more than one is available for a given subject name.
The value of this extension should be calculated by performing a SHA-1 hash of the certificate's DER-encoded subjectPublicKey, as recommended by PKIX. The Subject Key Identifier extension is used in conjunction with the Authority Key Identifier extension for CA certificates. If the CA certificate has a Subject Key Identifier extension, the key identifier in the Authority Key Identifier extension of the certificate being verified should match the key identifier of the CA's Subject Key Identifier extension. It is not necessary for the verifier to recompute the key identifier in this case.
PKIX Part 1 requires this extension for all CA certificates and recommends it for all other certificates.
OID

2.5.29.14

Criticality

This extension is always noncritical.

B.4. CRL Extensions
Copy link

B.4.1. About CRL Extensions
Copy link

Since its initial publication, the X.509 standard for CRL formats has been amended to include additional information within a CRL. This information is added through CRL extensions.
The extensions defined by ANSI X9 and ISO/IEC/ITU for X.509 CRLs [X.509] [X9.55] allow additional attributes to be associated with CRLs. The Internet X.509 Public Key Infrastructure Certificate and CRL Profile, available at RFC 5280, recommends a set of extensions to be used in CRLs. These extensions are called standard CRL extensions.
The standard also allows custom extensions to be created and included in CRLs. These extensions are called private, proprietary, or custom CRL extensions and carry information unique to an organization or business. Applications may not able to validate CRLs that contain private critical extensions, so it is not recommended that custom extensions be used in a general context.

Note

Abstract Syntax Notation One (ASN.1) and Distinguished Encoding Rules (DER) standards are specified in the CCITT Recommendations X.208 and X.209. For a quick summary of ASN.1 and DER, see A Layman's Guide to a Subset of ASN.1, BER, and DER, which is available at RSA Laboratories' web site, http://www.rsa.com.
B.4.1.1. Structure of CRL Extensions
Copy link
A CRL extension consists of the following parts:
  • The object identifier (OID) for the extension. This identifier uniquely identifies the extension. It also determines the ASN.1 type of value in the value field and how the value is interpreted. When an extension appears in a CRL, the OID appears as the extension ID field (extnID) and the corresponding ASN.1 encoded structure appears as the value of the octet string (extnValue); examples are shown in Example B.4, “Sample Pretty-Print Certificate Extensions”.
  • A flag or Boolean field called critical.
    The true or false value assigned to this field indicates whether the extension is critical or noncritical to the CRL.
    • If the extension is critical and the CRL is sent to an application that does not understand the extension based on the extension's ID, the application must reject the CRL.
    • If the extension is not critical and the CRL is sent to an application that does not understand the extension based on the extension's ID, the application can ignore the extension and accept the CRL.
  • An octet string containing the DER encoding of the value of the extension.
The application receiving the CRL checks the extension ID to determine if it can recognize the ID. If it can, it uses the extension ID to determine the type of value used.
B.4.1.2. Sample CRL and CRL Entry Extensions
Copy link
The following is an example of an X.509 CRL version 2 extension. The Certificate System can display CRLs in readable pretty-print format, as shown here. As shown in the example, CRL extensions appear in sequence and only one instance of a particular extension may appear per CRL; for example, a CRL may contain only one Authority Key Identifier extension. However, CRL-entry extensions appear in appropriate entries in the CRL.

B.4.2. Standard X.509 v3 CRL Extensions Reference
Copy link

In addition to certificate extensions, the X.509 proposed standard defines extensions to CRLs, which provide methods for associating additional attributes with Internet CRLs. These are one of two kinds: extensions to the CRL itself and extensions to individual certificate entries in the CRL.

Table B.39. Authority Infomation Access Configuration Parameters
Parameter Description
enable Specifies whether the rule is enabled or disabled. The default is to have this extension disabled.
critical Sets whether the extension is marked as critical; the default is noncritical.
numberOfAccessDescriptions
Indicates the number of access descriptions, from 0 to any positive integer; the default is 0.
When setting this parameter to an integer other than 0, set the number, and then click OK to close the window. Re-open the edit window for the rule, and the fields to set the points will be present.
accessMethodn The only accepted value for this parameter is caIssuers. The caIssuers method is used when the information available lists certificates that can be used to verify the signature on the CRL. No other method should be used when the AIA extension is included in a CRL.
accessLocationTypen Specifies the type of access location for the n access description. The options are either DirectoryName or URI.
accessLocationn
If accessLocationType is set to DirectoryName, the value must be a string in the form of an X.500 name, similar to the subject name in a certificate. For example, CN=CACentral,OU=Research Dept,O=Example Corporation,C=US.
If accessLocationType is set to URI, the name must be a URI; the URI must be an absolute pathname and must specify the host. For example, http://testCA.example.com/get/crls/here/.
B.4.2.1.2. authorityKeyIdentifier
Copy link
The Authority Key Identifier extension for a CRL identifies the public key corresponding to the private key used to sign the CRL. For details, see the discussion under certificate extensions at Section B.3.2, “authorityKeyIdentifier”.
The PKIX standard recommends that the CA must include this extension in all CRLs it issues because a CA's public key can change, for example, when the key gets updated, or the CA may have multiple signing keys because of multiple concurrent key pairs or key changeover. In these cases, the CA ends up with more than one key pair. When verifying a signature on a certificate, other applications need to know which key was used in the signature.

Parameter Description
enable Sets whether the extension rule is enabled or disabled. By default, this is enabled.
critical Marks the extension as critical or noncritical. By default, this is noncritical.
Netscape defined certain certificate extensions for its products. Some of the extensions are now obsolete, and others have been superseded by the extensions defined in the X.509 proposed standard. All Netscape extensions should be tagged as noncritical, so that their presence in a certificate does not make that certificate incompatible with other clients.
B.4.3.1. netscape-cert-type
Copy link
The Netscape Certificate Type extension can be used to limit the purposes for which a certificate can be used. It has been replaced by the X.509 v3 extensions Section B.3.6, “extKeyUsage” and Section B.3.3, “basicConstraints”.
If the extension exists in a certificate, it limits the certificate to the uses specified in it. If the extension is not present, the certificate can be used for all applications, except for object signing.
The value is a bit-string, where the individual bit positions, when set, certify the certificate for particular uses as follows:
  • bit 0: TLS Client certificate
  • bit 1: TLS Server certificate
  • bit 2: S/MIME certificate
  • bit 3: Object Signing certificate
  • bit 4: reserved
  • bit 5: TLS CA certificate

enableClientAuth Sets whether to use client (certificate-based) authentication to access the OCSP service.
nickname Gives the nickname of the certificate in the OCSP service's database to use for client authentication. This is only used if the enableClientAuth option is set to true.

C.2. Mapper Plug-in Modules
Copy link

This section describes the mapper plug-in modules provided for the Certificate Manager. These modules configure a Certificate Manager to enable and configure specific mapper instances.
The available mapper plug-in modules include the following:

C.2.1. LdapCaSimpleMap
Copy link

The LdapCaSimpleMap plug-in module configures a Certificate Manager to create an entry for the CA in an LDAP directory automatically and then map the CA's certificate to the directory entry by formulating the entry's DN from components specified in the certificate request, certificate subject name, certificate extension, and attribute variable assertion (AVA) constants. For more information on AVAs, check the directory documentation.
The CA certificate mapper specifies whether to create an entry for the CA, to map the certificate to an existing entry, or to do both.
If a CA entry already exists in the publishing directory and the value assigned to the dnPattern parameter of this mapper is changed, but the uid and o attributes are the same, the mapper fails to create the second CA entry. For example, if the directory already has a CA entry for uid=CA,ou=Marketing,o=example.com and a mapper is configured to create another CA entry with uid=CA,ou=Engineering,o=example.com, the operation fails.
The operation may fail because the directory has the UID Uniqueness plug-in set to a specific base DN. This setting prevents the directory from having two entries with the same UID under that base DN. In this example, it prevents the directory from having two entries under o=example.com with the same UID, CA.
If the mapper fails to create a second CA entry, check the base DN to which the UID Uniqueness plug-in is set, and check if an entry with the same UID already exists in the directory. If necessary, adjust the mapper setting, remove the old CA entry, comment out the plug-in, or create the entry manually.
During installation, the Certificate Manager automatically creates two instances of the CA certificate mapper module. The mappers are named as follows:
Expand
Table C.8. LdapCaSimpleMap Configuration Parameters
Parameter Description
createCAEntry
Creates a CA's entry, if selected (default).
If selected, the Certificate Manager first attempts to create an entry for the CA in the directory. If the Certificate Manager succeeds in creating the entry, it then attempts to publish the CA's certificate to the entry. If this is not selected, the entry must already be present in order to publish to it.
dnPattern
Specifies the DN pattern the Certificate Manager should use to construct to search for the CA's entry in the publishing directory. The value of dnPattern can be a list of AVAs separated by commas. An AVA can be a variable, such as cn=$subj.cn, that the Certificate Manager can derive from the certificate subject name or a constant, such as o=Example Corporation.
If the CA certificate does not have the cn component in its subject name, adjust the CA certificate mapping DN pattern to reflect the DN of the entry in the directory where the CA certificate is to be published. For example, if the CA certificate subject DN is o=Example Corporation and the CA's entry in the directory is cn=Certificate Authority, o=Example Corporation, the pattern is cn=Certificate Authority, o=$subj.o.
  • Example 1: uid=CertMgr, o=Example Corporation
  • Example 2: cn=$subj.cn,ou=$subj.ou,o=$subj.o,c=US
  • Example 3: uid=$req.HTTP_PARAMS.uid, e=$ext.SubjectAlternativeName.RFC822Name,ou=$subj.ou
In the above examples, $req takes the attribute from the certificate request, $subj takes the attribute from the certificate subject name, and $ext takes the attribute from the certificate extension.
C.2.1.1. LdapCaCertMap
Copy link
The LdapCaCertMap mapper is an instance of the LdapCaSimpleMap module. The Certificate Manager automatically creates this mapper during installation.
This mapper creates an entry for the CA in the directory and maps the CA certificate to the CA's entry in the directory.
By default, the mapper is configured to create an entry for the CA in the directory, The default DN pattern for locating the CA's entry is as follows: 
uid=$subj.cn,ou=people,o=$subj.o
Copy to Clipboard Toggle word wrap
C.2.1.2. LdapCrlMap
Copy link
The LdapCrlMap mapper is an instance of the LdapCaSimpleMap module. The Certificate Manager automatically creates this mapper during installation.
This mapper creates an entry for the CA in the directory and maps the CRL to the CA's entry in the directory.
By default, the mapper is configured to create an entry for the CA in the directory. The default DN pattern for locating the CA's entry is as follows: 
uid=$subj.cn,ou=people,o=$subj.o
Copy to Clipboard Toggle word wrap

C.2.2. LdapDNExactMap
Copy link

The LdapDNExactMap plug-in module configures a Certificate Manager to map a certificate to an LDAP directory entry by searching for the LDAP entry DN that matches the certificate subject name. To use this mapper, each certificate subject name must exactly match a DN in a directory entry. For example, if the certificate subject name is uid=jdoe, o=Example Corporation, c=US, when searching the directory for the entry, the Certificate Manager only searches for an entry with the DN uid=jdoe, o=Example Corporation, c=US.
If no matching entries are found, the server returns an error and does not publish the certificate.
This mapper does not require any values for any parameters because it obtains all values from the certificate.

C.2.3. LdapSimpleMap
Copy link

The LdapSimpleMap plug-in module configures a Certificate Manager to map a certificate to an LDAP directory entry by deriving the entry's DN from components specified in the certificate request, certificate's subject name, certificate extension, and attribute variable assertion (AVA) constants. For more information on AVAs, see the directory documentation.
By default, the Certificate Manager uses mapper rules that are based on the simple mapper. During installation, the Certificate Manager automatically creates an instance of the simple mapper module, named LdapUserCertMap. The default mapper maps various types of end-entity certificates to their corresponding directory entries.
The simple mapper requires one parameter, dnPattern. The value of dnPattern can be a list of AVAs separated by commas. An AVA can be a variable, such as uid=$subj.UID, or a constant, such as o=Example Corporation.
  • Example 1: uid=CertMgr, o=Example Corporation
  • Example 2: cn=$subj.cn,ou=$subj.ou,o=$subj.o,c=US
  • Example 3: uid=$req.HTTP_PARAMS.uid, e=$ext.SubjectAlternativeName.RFC822Name,ou=$subj.ou
In the examples, $req takes the attribute from the certificate request, $subj takes the attribute from the certificate subject name, and $ext takes the attribute from the certificate extension.

C.2.4. LdapSubjAttrMap
Copy link

The LdapSubjAttrMap plug-in module configures a Certificate Manager to map a certificate to an LDAP directory entry using a configurable LDAP attribute. To use this mapper, the directory entries must include the specified LDAP attribute.
This mapper requires the exact pattern of the subject DN because the Certificate Manager searches the directory for the attribute with a value that exactly matches the entire subject DN. For example, if the specified LDAP attribute is certSubjectDN and the certificate subject name is uid=jdoe, o=Example Corporation, c=US, the Certificate Manager searches the directory for entries that have the attribute certSubjectDN=uid=jdoe, o=Example Corporation, c=US.
If no matching entries are found, the server returns an error and writes it to the log.
Table C.9, “LdapSubjAttrMap Parameters” describes these parameters.
Expand
Table C.9. LdapSubjAttrMap Parameters
Parameter Description
certSubjNameAttr Specifies the name of the LDAP attribute that contains a certificate subject name as its value. The default is certSubjectName, but this can be configured to any LDAP attribute.
searchBase Specifies the base DN for starting the attribute search. The permissible value is a valid DN of an LDAP entry, such as o=example.com, c=US.

C.2.5. LdapDNCompsMap
Copy link

The LdapDNCompsMap plug-in module implements the DN components mapper. This mapper maps a certificate to an LDAP directory entry by constructing the entry's DN from components, such as cn, ou, o, and c, specified in the certificate subject name, and then uses it as the search DN to locate the entry in the directory. The mapper locates the following entries:
  • The CA's entry in the directory for publishing the CA certificate and the CRL.
  • End-entity entries in the directory for publishing end-entity certificates.
The mapper takes DN components to build the search DN. The mapper also takes an optional root search DN. The server uses the DN components to form an LDAP entry to begin a subtree search and the filter components to form a search filter for the subtree. If none of the DN components are configured, the server uses the base DN for the subtree. If the base DN is null and none of the DN components match, an error is returned. If none of the DN components and filter components match, an error is returned. If the filter components are null, a base search is performed.
Both the DNComps and filterComps parameters accept valid DN components or attributes separated by commas. The parameters do not accept multiple entries of an attribute; for example, filterComps can be set to cn,ou but not to cn,ou2,ou1. To create a filter with multiple instances of the same attribute, such as if directory entries contain multiple ou s, modify the source code for the LdapDNCompsMap module.
The following components are commonly used in DNs:
  • uid represents the user ID of a user in the directory.
  • cn represents the common name of a user in the directory.
  • ou represents an organizational unit in the directory.
  • o represents an organization in the directory.
  • l represents a locality (city).
  • st represents a state.
  • c represents a country.
For example, the following DN represents the user named Jane Doe who works for the Sales department at Example Corporation, which is located in Mountain View, California, United States: 
cn=Jane Doe, ou=Sales, o=Example Corporation, l=Mountain View, st=California, c=US
Copy to Clipboard Toggle word wrap
The Certificate Manager can use some or all of these components (cn, ou, o, l, st, and c) to build a DN for searching the directory. When creating a mapper rule, these components can be specified for the server to use to build a DN; that is, components to match attributes in the directory. This is set through the dnComps parameter.
For example, the components cn, ou, o, and c are set as values for the dnComps parameter. To locate Jane Doe's entry in the directory, the Certificate Manager constructs the following DN by reading the DN attribute values from the certificate, and uses the DN as the base for searching the directory: 
cn=Jane Doe, ou=Sales, o=Example Corporation, c=US
Copy to Clipboard Toggle word wrap
  • A subject name does not need to have all of the components specified in the dnComps parameter. The server ignores any components that are not part of the subject name, such as l and st in this example.
  • Unspecified components are not used to build the DN. In the example, if the ou component is not included, the server uses this DN as the base for searching the directory: 
    cn=Jane Doe, o=Example Corporation, c=US
    Copy to Clipboard Toggle word wrap
For the dnComps parameter, enter those DN components that the Certificate Manager can use to form the LDAP DN exactly. In certain situations, however, the subject name in a certificate may match more than one entry in the directory. Then, the Certificate Manager might not get a single, distinct matching entry from the DN. For example, the subject name cn=Jane Doe, ou=Sales, o=Example Corporation, c=US might match two users with the name Jane Doe in the directory. If that occurs, the Certificate Manager needs additional criteria to determine which entry corresponds to the subject of the certificate.
To specify the components the Certificate Manager must use to distinguish between different entries in the directory, use the filterComps parameter; for details, see Table C.10, “LdapDNCompsMap Configuration Parameters”. For example, if cn, ou, o, and c are values for the dnComps parameter, enter l for the filterComps parameter only if the l attribute can be used to distinguish between entries with identical cn, ou, o, and c values.
If the two Jane Doe entries are distinguished by the value of the uid attribute ‐ one entry's uid is janedoe1, and the other entry's uid is janedoe2 ‐ the subject names of certificates can be set to include the uid component.

Note

The e, l, and st components are not included in the standard set of certificate request forms provided for end entities. These components can be added to the forms, or the issuing agents can be required to insert these components when editing the subject name in the certificate issuance forms.
With this configuration, a Certificate Manager maps its certificates with the ones in the LDAP directory by using the dnComps values to form a DN and the filterComps values to form a search filter for the subtree.
  • If the formed DN is null, the server uses the baseDN value for the subtree. If both the formed DN and base DN are null, the server logs an error.
  • If the filter is null, the server uses the baseDN value for the search. If both the filter and base DN are null, the server logs an error.
Table C.10, “LdapDNCompsMap Configuration Parameters” describes these parameters.
Expand
Table C.10. LdapDNCompsMap Configuration Parameters
Parameter Description
baseDN Specifies the DN to start searching for an entry in the publishing directory. If the dnComps field is blank, the server uses the base DN value to start its search in the directory.
dnComps
Specifies where in the publishing directory the Certificate Manager should start searching for an LDAP entry that matches the CA's or the end entity's information.
For example, if dnComps uses the o and c attributes of the DN, the server starts the search from the o=org, c=country entry in the directory, where org and country are replaced with values from the DN in the certificate.
If the dnComps field is empty, the server checks the baseDN field and searches the directory tree specified by that DN for entries matching the filter specified by filterComps parameter values.
The permissible values are valid DN components or attributes separated by commas.
filterComps
Specifies components the Certificate Manager should use to filter entries from the search result. The server uses the filterComps values to form an LDAP search filter for the subtree. The server constructs the filter by gathering values for these attributes from the certificate subject name; it uses the filter to search for and match entries in the LDAP directory.
If the server finds more than one entry in the directory that matches the information gathered from the certificate, the search is successful, and the server optionally performs a verification. For example, if filterComps is set to use the email and user ID attributes (filterComps=e,uid), the server searches the directory for an entry whose values for email and user ID match the information gathered from the certificate.
The permissible values are valid directory attributes in the certificate DN separated by commas. The attribute names for the filters need to be attribute names from the certificate, not from ones in the LDAP directory. For example, most certificates have an e attribute for the user's email address; LDAP calls that attribute mail.

Appendix D. ACL Reference
Copy link

This section describes what each resource controls, lists the possible operations describing the outcome of those operations, and provides the default ACIs for each ACL resource defined. Each subsystem contains only those ACLs that are relevant to that subsystem.

D.1. About ACL Configuration Files
Copy link

Access control is the method to set rules on who can access part of a server and the operations that user can perform. The four subsystems which depend on the LDAP directory service and use a Java console — the CA, KRA, OCSP, and TKS — all implement LDAP-style access control to access their resources. These access control lists (ACLs) are located in the acl.ldif files in the instance's /var/lib/pki/instance_name/conf directory.

Note

This section provides only a very brief overview of access control concepts. Access control is described in much more detail in Managing Access Control in the Red Hat Directory Server Administration Guide.
The Certificate System ACL files are LDIF files that are loaded by the internal database. The individual ACLs are defined as resourceACLS attributes which identify the area of the subsystem being protected and then a list of all of the specific access controls being set. 
resourceACLS: class_name:all rights: allow|deny (rights)  type=target description
Copy to Clipboard Toggle word wrap
Each rule which allows or denies access to a resource is called an access control instruction (ACI). (The sum of all of the ACIs for a resource is an access control list.) Before defining the actual ACI, the ACL attribute is first applied to a specific plug-in class used by the Certificate System subsystem. This focuses each ACL to a specific function performed by the subsystem, providing both more security for the instance and better control over applying ACLs.

Example D.1. Default ACL to List Certificate Profiles

resourceACLS: certServer.ca.profiles:list:allow (list)  group="Certificate Manager Agents":Certificate Manager agents may list profiles
Copy to Clipboard Toggle word wrap
Because each subsystem (CA, KRA, OCSP, and TKS) has different resources for its operations, each subsystem instance has its own acl.ldif file and its own defined ACLs.
Each ACI defines what access or behavior can be done (the right) and who the ACI applies to (the target). The basic format of an ACI is, then: 
allow|deny (rights) user|group
Copy to Clipboard Toggle word wrap
Rights are types of operations that the ACI allows a user to perform. For LDAP ACIs, there is a relatively limited list of rights to directory entries, like search, read, write, and delete. The Certificate System uses additional rights that cover common PKI tasks, like revoke, submit, and assign.
If an operation is not explicitly allowed in an ACI, then it is implicitly denied. If an operation is explicitly denied in one ACI, then it trumps any ACI which explicitly allows it. Deny rules are always superior to allow rules to provide additional security.
Each ACI has to apply to specific users or groups. This is set using a couple of common conditions, usually user= or group=, though there are other options, like ipaddress= which defines client-based access rather than entry-based access. If there is more than one condition, the conditions can be composed using the double pipe (||) operator, signifying logical disjunction ("or"), and the double ampersand (&&) operator, signifying logical conjunction ("and"). For example, group="group1" || "group2".
Each area of the resourceACLS attribute value is defined in Table D.1, “Sections of the ACL Attribute Value”.
Expand
Table D.1. Sections of the ACL Attribute Value
Value Description
class_name The plug-in class to which the ACI is applied.
all operations The list of every operation covered in the ACI definition. There can be multiple operations in a single ACI and multiple ACIs in a single resourceACLS attribute.
allow|deny Whether the action is being allowed for the target user or group or denied to the target user or group.
(operations) The operations being allowed or denied.
type=target The target to identify who this applies to. This is commonly a user (such as user="name") or a group (group="group"). If there is more than one condition, the conditions can be composed using the double pipe (||) operator (logical "or") and the double ampersand (&&) operator (logical "and"). For example, group="group1" || "group2".
description A description of what the ACL is doing.

D.2. Common ACLs
Copy link

This section covers the default access control configuration that is common for all four subsystem types. These access control rules manage access to basic and common configuration settings, such as logging and adding users and groups.

Important

These ACLs are common in that the same ACLs occur in each subsystem instance's acl.ldif file. These are not shared ACLs in the sense that the configuration files or settings are held in common by all subsystem instances. As with all other instance configuration, these ACLs are maintained independently of other subsystem instances, in the instance-specific acl.ldif file.

access control
The process of controlling what particular users are allowed to do. For example, access control to servers is typically based on an identity, established by a password or a certificate, and on rules regarding what that entity can do. See also access control list (ACL).
access control instructions (ACI)
An access rule that specifies how subjects requesting access are to be identified or what rights are allowed or denied for a particular subject. See access control list (ACL).
access control list (ACL)
A collection of access control entries that define a hierarchy of access rules to be evaluated when a server receives a request for access to a particular resource. See access control instructions (ACI).
administrator
The person who installs and configures one or more Certificate System managers and sets up privileged users, or agents, for them. See also agent.
Advanced Encryption Standard (AES)
The Advanced Encryption Standard (AES), like its predecessor Data Encryption Standard (DES), is a FIPS-approved symmetric-key encryption standard. AES was adopted by the US government in 2002. It defines three block ciphers, AES-128, AES-192 and AES-256. The National Institute of Standards and Technology (NIST) defined the AES standard in U.S. FIPS PUB 197. For more information, see http://csrc.nist.gov/publications/fips/fips197/fips-197.pdf.
agent
A user who belongs to a group authorized to manage agent services for a Certificate System manager. See also Certificate Manager agent, Key Recovery Authority agent.
agent services
1. Services that can be administered by a Certificate System agent through HTML pages served by the Certificate System subsystem for which the agent has been assigned the necessary privileges.
2. The HTML pages for administering such services.
agent-approved enrollment
An enrollment that requires an agent to approve the request before the certificate is issued.
APDU
Application protocol data unit. A communication unit (analogous to a byte) that is used in communications between a smart card and a smart card reader.
attribute value assertion (AVA)
An assertion of the form attribute = value, where attribute is a tag, such as o (organization) or uid (user ID), and value is a value such as "Red Hat, Inc." or a login name. AVAs are used to form the distinguished name (DN) that identifies the subject of a certificate, called the subject name of the certificate.
audit log
A log that records various system events. This log can be signed, providing proof that it was not tampered with, and can only be read by an auditor user.
auditor
A privileged user who can view the signed audit logs.
authentication
Confident identification; assurance that a party to some computerized transaction is not an impostor. Authentication typically involves the use of a password, certificate, PIN, or other information to validate identity over a computer network. See also password-based authentication, certificate-based authentication, client authentication, server authentication.
authentication module
A set of rules (implemented as a Java™ class) for authenticating an end entity, agent, administrator, or any other entity that needs to interact with a Certificate System subsystem. In the case of typical end-user enrollment, after the user has supplied the information requested by the enrollment form, the enrollment servlet uses an authentication module associated with that form to validate the information and authenticate the user's identity. See servlet.
authorization
Permission to access a resource controlled by a server. Authorization typically takes place after the ACLs associated with a resource have been evaluated by a server. See access control list (ACL).
automated enrollment
A way of configuring a Certificate System subsystem that allows automatic authentication for end-entity enrollment, without human intervention. With this form of authentication, a certificate request that completes authentication module processing successfully is automatically approved for profile processing and certificate issuance.

CA certificate
A certificate that identifies a certificate authority. See also certificate authority (CA), subordinate CA, root CA.
CA hierarchy
A hierarchy of CAs in which a root CA delegates the authority to issue certificates to subordinate CAs. Subordinate CAs can also expand the hierarchy by delegating issuing status to other CAs. See also certificate authority (CA), subordinate CA, root CA.
CA server key
The TLS server key of the server providing a CA service.
CA signing key
The private key that corresponds to the public key in the CA certificate. A CA uses its signing key to sign certificates and CRLs.
certificate
Digital data, formatted according to the X.509 standard, that specifies the name of an individual, company, or other entity (the subject name of the certificate) and certifies that a public key, which is also included in the certificate, belongs to that entity. A certificate is issued and digitally signed by a certificate authority (CA). A certificate's validity can be verified by checking the CA's digital signature through public-key cryptography techniques. To be trusted within a public-key infrastructure (PKI), a certificate must be issued and signed by a CA that is trusted by other entities enrolled in the PKI.
certificate authority (CA)
A trusted entity that issues a certificate after verifying the identity of the person or entity the certificate is intended to identify. A CA also renews and revokes certificates and generates CRLs. The entity named in the issuer field of a certificate is always a CA. Certificate authorities can be independent third parties or a person or organization using certificate-issuing server software, such as Red Hat Certificate System.
certificate chain
A hierarchical series of certificates signed by successive certificate authorities. A CA certificate identifies a certificate authority (CA) and is used to sign certificates issued by that authority. A CA certificate can in turn be signed by the CA certificate of a parent CA, and so on up to a root CA. Certificate System allows any end entity to retrieve all the certificates in a certificate chain.
certificate extensions
An X.509 v3 certificate contains an extensions field that permits any number of additional fields to be added to the certificate. Certificate extensions provide a way of adding information such as alternative subject names and usage restrictions to certificates. A number of standard extensions have been defined by the PKIX working group.
certificate fingerprint
A one-way hash associated with a certificate. The number is not part of the certificate itself, but is produced by applying a hash function to the contents of the certificate. If the contents of the certificate changes, even by a single character, the same function produces a different number. Certificate fingerprints can therefore be used to verify that certificates have not been tampered with.
Certificate Management Message Formats (CMMF)
Message formats used to convey certificate requests and revocation requests from end entities to a Certificate Manager and to send a variety of information to end entities. A proposed standard from the Internet Engineering Task Force (IETF) PKIX working group. CMMF is subsumed by another proposed standard, Certificate Management Messages over Cryptographic Message Syntax (CMC). For detailed information, see https://tools.ietf.org/html/draft-ietf-pkix-cmmf-02.
Certificate Management Messages over Cryptographic Message Syntax (CMC)
Message format used to convey a request for a certificate to a Certificate Manager. A proposed standard from the Internet Engineering Task Force (IETF) PKIX working group. For detailed information, see https://tools.ietf.org/html/draft-ietf-pkix-cmc-02.
Certificate Manager
An independent Certificate System subsystem that acts as a certificate authority. A Certificate Manager instance issues, renews, and revokes certificates, which it can publish along with CRLs to an LDAP directory. It accepts requests from end entities. See certificate authority (CA).
Certificate Manager agent
A user who belongs to a group authorized to manage agent services for a Certificate Manager. These services include the ability to access and modify (approve and reject) certificate requests and issue certificates.
certificate profile
A set of configuration settings that defines a certain type of enrollment. The certificate profile sets policies for a particular type of enrollment along with an authentication method in a certificate profile.
Certificate Request Message Format (CRMF)
Format used for messages related to management of X.509 certificates. This format is a subset of CMMF. See also Certificate Management Message Formats (CMMF). For detailed information, see https://tools.ietf.org/html/rfc2511.
certificate revocation list (CRL)
As defined by the X.509 standard, a list of revoked certificates by serial number, generated and signed by a certificate authority (CA).
Certificate System
See Red Hat Certificate System, Cryptographic Message Syntax (CS).
Certificate System console
A console that can be opened for any single Certificate System instance. A Certificate System console allows the Certificate System administrator to control configuration settings for the corresponding Certificate System instance.
Certificate System subsystem
One of the five Certificate System managers: Certificate Manager, Online Certificate Status Manager, Key Recovery Authority, Token Key Service, or Token Processing System.
certificate-based authentication
Authentication based on certificates and public-key cryptography. See also password-based authentication.
chain of trust
See certificate chain.
chained CA
See linked CA.
cipher
See cryptographic algorithm.
client authentication
The process of identifying a client to a server, such as with a name and password or with a certificate and some digitally signed data. See certificate-based authentication, password-based authentication, server authentication.
client TLS certificate
A certificate used to identify a client to a server using the TLS protocol. See Transport Layer Security (TLS).
CMC
See Certificate Management Messages over Cryptographic Message Syntax (CMC).
CMC Enrollment
Features that allow either signed enrollment or signed revocation requests to be sent to a Certificate Manager using an agent's signing certificate. These requests are then automatically processed by the Certificate Manager.
CMMF
See Certificate Management Message Formats (CMMF).
Common Criteria
A certification standard that evaluates computer security, both for software and hardware components. The software or hardware vendor defines the operating environment and specified configuration, identifies any threats, and outlines both the development and deployment processes for the target of evaluation (the thing being evaluated). The Common Criteria certification laboratory then tests the implementation design to look for any vulnerabilities.
CRL
See certificate revocation list (CRL).
CRMF
See Certificate Request Message Format (CRMF).
cross-certification
The exchange of certificates by two CAs in different certification hierarchies, or chains. Cross-certification extends the chain of trust so that it encompasses both hierarchies. See also certificate authority (CA).
cross-pair certificate
A certificate issued by one CA to another CA which is then stored by both CAs to form a circle of trust. The two CAs issue certificates to each other, and then store both cross-pair certificates as a certificate pair.
cryptographic algorithm

D
Copy link

decryption
Unscrambling data that has been encrypted. See encryption.
delta CRL
A CRL containing a list of those certificates that have been revoked since the last full CRL was issued.
digital ID
See certificate.
digital signature
To create a digital signature, the signing software first creates a one-way hash from the data to be signed, such as a newly issued certificate. The one-way hash is then encrypted with the private key of the signer. The resulting digital signature is unique for each piece of data signed. Even a single comma added to a message changes the digital signature for that message. Successful decryption of the digital signature with the signer's public key and comparison with another hash of the same data provides tamper detection. Verification of the certificate chain for the certificate containing the public key provides authentication of the signer. See also nonrepudiation, encryption.
distinguished name (DN)
A series of AVAs that identify the subject of a certificate. See attribute value assertion (AVA).
distribution points
Used for CRLs to define a set of certificates. Each distribution point is defined by a set of certificates that are issued. A CRL can be created for a particular distribution point.
dual key pair
Two public-private key pairs, four keys altogether, corresponding to two separate certificates. The private key of one pair is used for signing operations, and the public and private keys of the other pair are used for encryption and decryption operations. Each pair corresponds to a separate certificate. See also encryption key, public-key cryptography, signing key.
Key Recovery Authority
An optional, independent Certificate System subsystem that manages the long-term archival and recovery of RSA encryption keys for end entities. A Certificate Manager can be configured to archive end entities' encryption keys with a Key Recovery Authority before issuing new certificates. The Key Recovery Authority is useful only if end entities are encrypting data, such as sensitive email, that the organization may need to recover someday. It can be used only with end entities that support dual key pairs: two separate key pairs, one for encryption and one for digital signatures.
Key Recovery Authority agent
A user who belongs to a group authorized to manage agent services for a Key Recovery Authority, including managing the request queue and authorizing recovery operation using HTML-based administration pages.
Key Recovery Authority recovery agent
One of the m of n people who own portions of the storage key for the Key Recovery Authority.
Key Recovery Authority storage key
Special key used by the Key Recovery Authority to encrypt the end entity's encryption key after it has been decrypted with the Key Recovery Authority's private transport key. The storage key never leaves the Key Recovery Authority.
Key Recovery Authority transport certificate
Certifies the public key used by an end entity to encrypt the entity's encryption key for transport to the Key Recovery Authority. The Key Recovery Authority uses the private key corresponding to the certified public key to decrypt the end entity's key before encrypting it with the storage key.

See also Key Recovery Authority transport certificate.
public key
One of a pair of keys used in public-key cryptography. The public key is distributed freely and published as part of a certificate. It is typically used to encrypt data sent to the public key's owner, who then decrypts the data with the corresponding private key.
public-key cryptography
A set of well-established techniques and standards that allow an entity to verify its identity electronically or to sign and encrypt electronic data. Two keys are involved, a public key and a private key. A public key is published as part of a certificate, which associates that key with a particular identity. The corresponding private key is kept secret. Data encrypted with the public key can be decrypted only with the private key.

A cryptographic algorithm used to create digital signatures. Certificate System supports the MD5 and SHA-1 signing algorithms. See also cryptographic algorithm, digital signature.
signed audit log
See audit log.
signing certificate
A certificate whose public key corresponds to a private key used to create digital signatures. For example, a Certificate Manager must have a signing certificate whose public key corresponds to the private key it uses to sign the certificates it issues.

2. The ability for a user to log in once to a single computer and be authenticated automatically by a variety of servers within a network. Partial single sign-on solutions can take many forms, including mechanisms for automatically tracking passwords used with different servers. Certificates support single sign-on within a public-key infrastructure (PKI). A user can log in once to a local client's private-key database and, as long as the client software is running, rely on certificate-based authentication to access each server within an organization that the user is allowed to access.
slot
The portion of a PKCS #11 module, implemented in either hardware or software, that contains a token.
smart card
A small device that contains a microprocessor and stores cryptographic information, such as keys and certificates, and performs cryptographic operations. Smart cards implement some or all of the PKCS #11 interface.
spoofing
Pretending to be someone else. For example, a person can pretend to have the email address jdoe@example.com, or a computer can identify itself as a site called www.redhat.com when it is not. Spoofing is one form of impersonation. See also misrepresentation.
