Yup! And it's simple enough to do this automatically by just putting this in your gitconfig:

    [user]
        signingkey = <your GPG fingerprint here>
    [commit]
        gpgsign = true

You don't need signingkey if you have a GPG key with the same email as your git user.email (I guess that's the majority of cases).
