Optionally enable AES 256-bit encryption

If you want to use AES 256-bit encryption, you must install the Java Cryptography Extension (JCE) jurisdiction policy files by copying them into the Java home directory of each Edge Encryption proxy server host machine.

About this task

Your Java home directory includes the AES 128-bit policy files by default. To enable AES 256-bit encryption, you must overwrite the Java home directory policy files with the AES 256-bit policy files. It is only necessary to download the JCE once, but every Edge Encryption proxy server host machine must be updated.

Note: If upgrading an Edge Encryption proxy server running on Windows to a new version of Java, you may need to copy the JCE policy files from your previous Java folder to the new Java folder.


  1. Download the JCE policy 8 ZIP file from Oracle.
  2. Unzip the file.
  3. On each proxy server host machine, copy the local_policy.jar and US_export_policy.jar files into the <Java-home-directory>/jre/lib/security folder.
