Attending my first signing party


The social part

It was a drawn-out experience, standing for about 90 minutes checking (foreign) passports. But it was fun, meeting many new people and also getting some feedback for my talk.
I now also know much more about the security features of my own passport than ever.

The technical part

Signing about 60 keys (+ much more subkeys) is hard without some help of special programs. I used caff from the signingparty package to sign and send the keys.
Unfortunately there is no signingparty package for arch and I discovered the caff-svn package in aur too late.
So I make my own PKGBUILD file, which is not fully complete and so I don't upload it to aur. (x86_64 PKG)
I followed the howto on eurion.net to configure caff.

To import the signatures from my mail account I wrote a small python script to load all signature mails from my imaps server, decrypt it and import it to my keyring. You can get the script at github.
