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. If your site decides to use the default key, no further configuration of your system is required to implement AES encryption. However, if your site requires or desires a unique encryption key, you can generate a unique key using the PSCipher command line utility as described in this documentation.

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.
