The encryption routines (APIs) allow you to program encryption
    operations into applications. OpenVMS Version 8.3 Integrity
    servers and Alpha systems support the Advanced Encryption
    Standard (AES) algorithm, which allows any OpenVMS user,
    system manager, security manager, or programmer to secure their
    files, save sets, or application data with AES Encryption. The
    former DES algorithm is also supported for complete backward
    compatibility. This allows updating archived data encrypted with
    DES to the more secure AES encryption algorithm.
