git – Land of Brozkeff

GitHub shows „Verified“ on commits signed by authorized GnuPG key. If you enable Vigilant mode, unsigned commits become marked as Unverified.

This is a quick cheatsheet how to create set of signing keys, set git to use it for commits, and add the key to GitHub as authorized key. Should work on Ubuntu/Debian Linux out of the box if you have GnuPG and Git already installed.
