Caution Using this feature in an exisiting configuration can break your Trustbuilder configuration.
Adding more security to the TrustBuilder Passwords is a good practice to a more secure installation. When using a password key file , TrustBuilder uses the key as a symmetric key encryption.
This feature is enabled through adding a JVM Option. The file must be readable for the Application Server. It can either be in a file or as a string in JNDI
