Chapter 2. Authentication and Security
2.1. TLS/SSL Certification
The Red Hat Enterprise Virtualization Manager API requires Hypertext Transfer Protocol Secure (HTTPS) [1] for secure interaction with client software, such as the Manager's SDK and CLI components. This involves a process of obtaining a certificate from the Red Hat Enterprise Virtualization Manager and importing it into the certificate store of your client.
Important
Obtain your certificate from the Red Hat Enterprise Virtualization Manager using a secure network connection.
Procedure 2.1. Obtaining a Certificate
You can obtain a certificate from the Red Hat Enterprise Virtualization Manager and transfer it to the client machine using one of three methods:
- Method 1 - Use a command line tool to download the certificate from the Manager. Examples of command line tools include cURL and Wget, both of which are available on multiple platforms.
- If using cURL:
$ curl -o rhevm.cer http://[rhevm-server]/ca.crt
- If using Wget:
$ wget -O rhevm.cer http://[rhevm-server]/ca.crt
- Method 2 - Use a web browser to navigate to the certificate located at:
http://[rhevm-server]/ca.crt
Depending on the chosen browser, the certificate either downloads or imports into the browser's keystore.- If the browser downloads the certificate: save the file as
rhevm.cer.If the browser imports the certificate: export it from the browser's certification options and save it asrhevm.cer.
- Method 3 - Log in to the Manager, export the certificate from the truststore and copy it to your client machine.
- Log in to the Manager as the
rootuser. - Export the certificate from the truststore using the Java keytool management utility:
$ keytool -exportcert -keystore /etc/pki/ovirt-engine/.truststore -alias cacert -storepass mypass -file rhevm.cer
This creates a certificate file calledrhevm.cer. - Copy the certificate to the client machine using the
scpcommand:$ scp rhevm.cer [username]@[client-machine]:[directory]
Each of these methods results in a certificate file named
rhevm.cer on your client machine. An API user imports this file into the certificate store of the client.
Procedure 2.2. Importing a Certificate to a Client
- Importing a certificate to a client relies on how the client itself stores and interprets certificates. This guide contains some examples on importing certificates. For clients not using Network Security Services (NSS) or Java KeyStore (JKS), see your client documentation for more information on importing a certificate.
