Well, I got a LOT of miscellaneous replies to my "Devils advocate" letter... No, I haven't gone thru the source code, and no, I don't know all there is to know about it. I didn't claim I did. I was just curious as to how "legitimate" the PGP encryption scheme was... Thanks to all who replied kindly... (Some people are sooo rude though!) Sorry to have peeved a few of you off so. Happy Hacking! Farmer Pete PS--I must say, this is the most mail I've recieved in a while from ANY reply!
