Re: signing commits with openssl/PKCS#11

Hy!

I would like to sign each commit with a X.509 certificate and a private key
stored on a PKCS#11 token. I assume that that should be possible somehow using
a hook which calls openssl. Does somebody know a working implementation of
this?

Creating signatures from an rsa key on a pkcs11 token should be
possible, but gnupg doesn't support pkcs11 for philosophical reasons.
You need to use gnupg-pkcs11 which is maintained outside of the gnupg
tree.

Once you configure gnupg-pkcs11-scd, you'll be able to use git and gpg
to sign tags as usual.

I configured this a while back for use with CAC cards using the
following resources:

   http://alpha.uwb.edu.pl/map/eToken_gpg_howto.shtml (dead)
   http://alpha.uwb.edu.pl/amicke/eToken_gpg_howto.shtml (replacement
for above?)
   http://gnupg-pkcs11.sourceforge.net/man.html

Try those docs.  If you have questions, I'll try to find my notes.
