Understanding the Advanced Encryption Standard (AES) Implementation

The PSCipher utility provides Advanced Encryption Standard (AES) for increased data security. When you install Enterprise PeopleTools on your application servers and web servers, a default, AES encryption key is provided. For security reasons, you must generate a unique encryption key using PSCipher command line utility as described in this documentation. The new key can be used to re-encrypt passwords included in your PeopleSoft environment files.

The version of the default encryption key is version 2.1, or {V2.1}. If you generate a unique key, the current version used by the system would be {V2.2}. Each time you generate a new key, the system increments the current version number.
