Sign your commits with Git and GPG on the command line

This article assumes you already have a private signing key in your GPG keychain.

Configure git to sign your commits by default. This is optional, but if you don't enable this option, you'll have to run git commit -S to sign each time.

git config --global commit.gpgsign true

To get GPG to ask for the password on the command line instead of a curses window:

Edit (or create) $HOME/.gnupg/gpg-gpg.conf:

pinentry-mode loopback

Edit (or create) $HOME/.gnupg/gpg-agent.conf:


Reload those changes by running:

gpgconf --kill gpg-agent

Finally add the following to $HOME/.bashrc, $HOME/.zshrc, etc:

export GPG_TTY=$(tty)

Start a new terminal or run source $HOME/.bashrc accept the new changes.
