A chapter in my eBook (http://iseries40.org) shows an MI implementation
of the new encryption standard (AES). It also shows a C-implementation
and explains why the C-implementation does a better job (better optimizer).
With V5R1, there is a built in AES implementation (in the CIPHER
instruction).
You can invoke CIPHER from RPG, so you have lots of choices.
