Please forgive me! It seems that the signature generated by the pgp 2.3 _IS_ good (according to 2.2), in any form. It's just that pgp 2.3 will not read a signature that is appended to an ascii message and ascii armored. If the signature is in a separate file, or if it isn't armored, it will read it fine. Just not a message with the signature block attached to it... So the problem is in the reading of the pgp signature block, not in the generation of the signature. I'm not very adept at programming, but am trying to work my way through it to see if I can find the problem. Sorry for the previous mistake. Again, maybe this is just my machine... sean
