If you could rule out nasty message altering sites, it might be easiest to just take a checksum of of the message (sans header and pgp signature) and sign that. If one is truely interested in making sure the sender was "real", just take the checksum of the message and check it against the signed result. Not 100% reliable, but then again, few things are. But what you are really trying to gain is "confidence" that the message is from who it says it is and this method should be descent enough for USENET or other public forums. ~mitch
