Is there a simple en/decryption method for strings?
This is for a wow add-on where a string is sent out into hidden message channel and picked up by the same add-on on someone elses pc. Basicly I'm not look looking to stop smart people but I don't want ppl to easly trick my add-on by just typing stuff in that channel.
Note: Please note that I'm limited on string length in the channel.
