    So if the keys weren't the problem. Something must have changed
    in the plain text that was signed, before it reached you, that
    made it fail the verify...

    So, when it says "BAD signature", it's talking about the signature of
    the message?

    Hmmm. A single char difference (maybe the odd =20 char) gets
    introduced) and messes up the "signature" of the message.

    I see that happening when I need to copy/paste the contents of a PGP
    block and paste it into my BlackBerry's pgp decryptor window. It always
    seem to return an error and never decrypts.
