Import a .p12 cert to GPG for signing debian packages

Question

I am currently signing some debian .deb packages with a self-signed PGP certificate, which I obtained from a collegue. Hence I have the following files in my folder `~/.gnupg/:

• gpg.conf (Currently only comments)
• pubring.gpg
• random_seed
• secring.gpg
• trustdb.gpg

I now obtained a properly signed certificate in .pfx format (or a .p12 exported from Keychain) which I should use to sign my debian packages. I have been looking on Google for quite a bit to figure out, how to convert the certificate. What I am looking for at the moment is an easy way to convert the .pfx to the file structure above, so that I can continue signing my debian packages with the new certificate.

Thanks very much for your help!

Answer 1

X.509 infrastructure and OpenPGP are two different technologies. You can't convert X.509 certificate to OpenPGP key (though you can use the the keypair from the certificate for a new OpenPGP key).
