I think I see what's going wrong here. On my card, OPENPGP.3 refers to the
authentication key. If you are trying to use this to decrypt stuff, the card
will outright refuse. Only the encryption key of the card will decrypt stuff,
and that one should refuse to sign. The other two will only sign stuff.



I use the GNU Privacy Guard (GnuPG) in combination with Enigmail.
You can send me encrypted mail if you want some privacy.
My key is available at <>
