Hi again, I managed to get a KEYID (5th field) via the "gpg --list-key --with-colon" and use it like the --help file recommended: gpg --trusted-key 1234567890ABCDEF AND it ask me for a message, after I type in something and press ctrl-D, it tells me "no valid OpenPGP data found". Arrgggg.....what is wrong? Warum ist dis? :-P Edward
