Chapter 37. Securing passwords with a keystore You can use a keystore to encrypt passwords that are used for communication between Business Central and KIE Server. You should encrypt both controller and KIE Server passwords. If Business Central and KIE 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. Note If KIE Server is not configured with JCEKS, KIE Server passwords are stored in system properties in plain text form. Prerequisites KIE Server is installed in Red Hat JBoss Web Server. Java 8 or higher is installed. Procedure Open the JWS_HOME /tomcat/conf/tomcat-users.xml file in a text editor. Add a KIE Server user with the kie-server role to the JWS_HOME /tomcat/conf/tomcat-users.xml file. In the following example, replace <USER_NAME> and <PASSWORD> with the user name and password of your choice. To use KeyTool to create a JCEKS, enter the following command in the Java 8 home directory: USD<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 KIE Server user that you created. To set the system properties, complete one of these steps in the JWS_HOME /tomcat/bin directory and replace the variables as described in the following table: Note If Business Central or the standalone controller are installed in separate instances from Red Hat JBoss Web Server, do not add the kie.keystore.key.server.alias and kie.keystore.key.server.pwd properties to CATALINA_OPTS . On Linux or UNIX, create the setenv.sh file with the following content: On Windows, add the following content to the setenv.bat file: Table 37.1. System properties used to load a KIE 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.jceks kie.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.pwd <KEY_CONTROL_PWD> Password of the alias for default REST Process Automation Controller with the stored password Start KIE Server to verify the configuration.
