Thanks for pointing out that the signature key and the authentication keys are identical:

I thought the long key ID is the last 16 characters of the fingerprint. And the fingerprint is a 40 character hash of the public (or private?) key. _______________________________________________ Gnupg-users mailing list Gnupg-users@gnupg.org https://lists.gnupg.org/mailman/listinfo/gnupg-users
