Using TC Trustcenter.de certificates

[Markus Plail]

Hi there!

I'd like to use gpg with the free certificates from TC Trustcenter.de. I
managed to import my private/public key into gpgsm and the Trustcenter
CA certificates into gpg, but I can't get my private/public key into
gpg. Originally I have a p12 certificate. Is it possible to extract the
keys in the needed format for gpg?

What I want to do in the end is sign/encrypt my emails with
Emacs/Gnus. I am using the latest versions of both in debian unstable.

thanks in advance and regards
Markus Plail
