Better don't do that.  That may break on when changing the passphrase.

At least for ssh keys this is easy:

  $ gpg-connect-agent 'keyinfo --ssh-fpr CFC82DE2AB8BD267A2C575F7553793ACE27AE54A' /bye
  S KEYINFO CFC82DE2AB8BD267A2C575F7553793ACE27AE54A D - - - P bd:50:eb:d0:8b:17:3d:78:36:44:e4:68:cc:8a:1f:1d - -

OpenPGP fingerprints are not available because the original goal was to
keep gpg-agent clear of protocol specific stuff.  However, given that we
already have ssh fingerprints (and OpenPGP import code), there is no
valid excuse for not adding v4 OpenPGP fingerprints here or in gpg.



Die Gedanken sind frei.  Ausnahmen regelt ein Bundesgesetz.
