GPG signing with Git and Github Desktop

Hi Github users,

You can now signed your commits on Github using at least Git 2.18.0 and Github Desktop 1.6.1.

  1. Generate a GPG key and add it to Github: (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)

  2. Configure Git properly by editing the .gitconfig file using the command line git config --global --edit in a terminal, then replace YOUR_GITHUB_EMAIL, YOUR_SIGNING_KEY and GPG_BINARY_PATH with your data

  name = Xavier Foucrier
  signingkey = YOUR_SIGNING_KEY
  program = GPG_BINARY_PATH
  gpgsign = true
  • YOUR_GITHUB_EMAIL: the email address used to login on Github
  • YOUR_SIGNING_KEY: the GPG key used to sign commits, should follow the GPG key ID convention, like this example:
  • GPG_BINARY_PATH: the GPG binary file path, depending on your Git install and your operating system:
    • Windows: gpg, gpg.exe or C:\\Program Files\\Git\\usr\\bin\\gpg.exe (can be found using where gpg in a terminal)
    • Mac or Linux: gpg or /usr/local/bin/gpg (can be found using which gpg in a terminal)
  1. Enjoy signed commits with your favorite code editor!

Note that you can temporary disable GPG signed commits by setting gpgsign = false in your .gitconfig file with git config --global commit.gpgsign false

That's all folks! 🎉
