Hi Github users,
You can now signed your commits on Github using at least Git 2.18.0 and Github Desktop 1.6.1.
You can find out a GPG key
gpg --list-secret-keys --keyid-format LONG and export it to a file
gpg --armor --export-secret-key -a YOUR_GITHUB_LOGIN by skipping the first point.
- Generate a GPG key and add it to Github: https://help.github.com/articles/generating-a-new-gpg-key (if you don't want to type a passphrase on every commit, you need to press "Enter" when the console will prompt you to type a passphrase)
