Sign your commits with your SSH key

Get the green "Verified" badge on GitHub, using the SSH key you already have.

Tell Git to sign every commit with your SSH key

Terminal

git config --global gpg.format ssh
git config --global user.signingkey ~/.ssh/id_ed25519.pub
git config --global commit.gpgsign true

No SSH key yet? Create one first with the SSH key page.

Copy the key and add it on GitHub as a Signing Key
Terminal
```
pbcopy < ~/.ssh/id_ed25519.pub
open https://github.com/settings/ssh/new
```
Set "Key type" to Signing Key. It's separate from the one you use to push.

Check it worked
