These kinds of messages show up in some Mail User Agents that don't know about PGP/MIME as though it is a message with an attachment, instead of a single signed message. In fact, the signature part is not an "attachment" in the traditional sense of the word, and it can only be evaluated in the context of the message it was sent with. For more detail on PGP/MIME, see https://tools.ietf.org/html/rfc3156 > when i try to open it it says > "Couldn't decrypt file: No data" this is probably because the data it is signing is missing (i.e. you are evaluating the signature without the message body itself) > What am i doing wrong here? If you want to be able to verify these message signatures, you should set yourself up with a Mail User Agent that can handle PGP/MIME-signed messages. Some examples are: * thunderbird with the enigmail plugin * evolution * claws mail * outlook with gpgOL (http://gpg4win.org/about.html) * notmuch hth, --dkg
signature.asc
