How to setup a GPG key in Git
This page is going to assume that a key has already been created on the system and added to GitHub through the web interface.
To set the list of keys on the system
gpg --list-secret-keys --keyid-format=long
To configure git to use the key
git config --global user.signingkey <keyid-from-step-above>
To set git to sign commits by default
git config --global commit.gpgsign true
To add the key to the .zshrc
(or .bashrc
)
#In ~/.zshrc
export GPG_TTY=$(tty)
If "keep my email private" has been enabled in GitHub, then the email associated with the key must match the no-reply email provided by GitHub.
