title: Import a .p12 cert to GPG for signing debian packages
body: <p>I am currently signing some debian <code>.deb</code> packages with a self-signed PGP certificate, which I obtained from a collegue. Hence I have the following files in my folder `~/.gnupg/:</p>
  
  <ul>
  <li>gpg.conf (Currently only comments)</li>
  <li>pubring.gpg</li>
  <li>random_seed</li>
  <li>secring.gpg</li>
  <li>trustdb.gpg</li>
  </ul>
  
  <p>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.</p>
  
  <p>Thanks very much for your help!</p>
