Re: Encryption question

Why not just hardcode the key in the program? Is this safe or can any
program be de-compiled?

The main problem I have had with the Cipher API is that when I save
encrypted data in a file I can not longer query that file or use
UPDDTA.

I've looked at the Cipher API, but I think I'm going to have a problem
with it. If I understand it correctly the API takes:

Text to be encrypted
Key
Encryption method

and returns:

encrypted data

And then basically the same thing to reverse the process. Now this
means I'll need to store a key somewhere (if I want to be able to
retrieve the data) which kind of defeats the purpose. Has anyone here
ever tried anything like this?

I was thinking about maybe storing the key in a PF that nobody has the
rights to but 1 program that would do the encrypting/decrypting.
However this seems kludgy.

Also, if anyone has ever written a procedure that uses this API in
RPG(ILE), I'd appreciate if you could post it.
