RE: MI a good use for encryption?

Guess I should've read the TOC before asking, eh?

I skimmed through the chapter, Leif, and apologize if this is answered but I
missed it; since AES is a standard, can I assume that we can encrypt on our
AS/400 and this can be decrypted on any other platform the data gets sent to
via the AES on that platform?  What happens if there are EBCDIC<>ASCII
translations involved?

No kidding!  Might be just the thing to get our sluggish V3R7 clients to get
current.  Is CIPHER an RPG opcode?  A built-in?  API?

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.
