Chapter 8. Securing passwords with a keystore
You can use a keystore to encrypt passwords that are used for communication between Business Central and Decision Server. You should encrypt both controller and Decision Server passwords. If Business Central and Decision Server are deployed to different application servers, then both application servers should use the keystore.
Use Java Cryptography Extension KeyStore (JCEKS) for your keystore because it supports symmetric keys. Use KeyTool, which is part of the JDK installation, to create a new JCEKS.
If Decision Server is not configured with JCEKS, Decision Server passwords are stored in system properties in plain text form.
Prerequisites
- Decision Server is installed in Oracle WebLogic Server.
-
A Decision Server user with the
kie-serverrole has been created, as described in Section 4.1, “Configuring the Decision Server group and users”. - Java 8 or higher is installed.
Procedure
To use KeyTool to create a JCEKS, enter the following command in the Java 8 home directory:
$<JAVA_HOME>/bin/keytool -importpassword -keystore <KEYSTORE_PATH> -keypass <ALIAS_KEY_PASSWORD> -alias <PASSWORD_ALIAS> -storepass <KEYSTORE_PASSWORD> -storetype JCEKS
In this example, replace the following variables:
-
<KEYSTORE_PATH>: The path where the keystore will be stored -
<KEYSTORE_PASSWORD>: The keystore password -
<ALIAS_KEY_PASSWORD>: The password used to access values stored with the alias -
<PASSWORD_ALIAS>: The alias of the entry to the process
-
- When prompted, enter the password for the Decision Server user that you created.
Set the system properties listed in the following table:
Table 8.1. System properties used to load a Decision Server JCEKS System property Placeholder Description kie.keystore.keyStoreURL<KEYSTORE_URL>URL for the JCEKS that you want to use, for example
file:///home/kie/keystores/keystore.jcekskie.keystore.keyStorePwd<KEYSTORE_PWD>Password for the JCEKS
kie.keystore.key.server.alias<KEY_SERVER_ALIAS>Alias of the key for REST services where the password is stored
kie.keystore.key.server.pwd<KEY_SERVER_PWD>Password of the alias for REST services with the stored password
kie.keystore.key.ctrl.alias<KEY_CONTROL_ALIAS>Alias of the key for default REST Process Automation Controller where the password is stored
kie.keystore.key.ctrl.key.ctrl.pwd<KEY_CONTROL_PWD>Password of the alias for default REST Process Automation Controller with the stored password
- Start Decision Server to verify the configuration.
