Chapter 8. Securing passwords with a keystore

You can use a keystore to encrypt passwords that are used for communication between Business Central and Process Server. You should encrypt both controller and Process Server passwords. If Business Central and Process 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 Process Server is not configured with JCEKS, Process Server passwords are stored in system properties in plain text form.

Prerequisites

Procedure

  1. 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
  2. When prompted, enter the password for the Process Server user that you created.
  3. Set the system properties listed in the following table:

    Table 8.1. System properties used to load a Process Server JCEKS

    System propertyPlaceholderDescription

    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

  4. Start Process Server to verify the configuration.
