Signing Git commits using SSH instead of GPG

TIL you can sign Git commits using SSH instead of GPG

This tip is 🏆, learned from my really smart colleague.

tl;dr;

To configure Git to use your key:

1. Configure Git to use SSH for commit signing:
   git config --global gpg.format ssh
2. Specify which public SSH key to use as the signing key and change the filename (~/.ssh/examplekey.pub) to the location of your key. The filename might differ, depending on how you generated your key:
   git config --global user.signingkey ~/.ssh/examplekey.pub

To sign a commit:

1. Use the -S flag when signing your commits:
   git commit -S -m "My commit msg"
2. Optional. If you don’t want to type the -S flag every time you commit, tell Git to sign your commits automatically:
   git config --global commit.gpgsign true
