# Methods of Signing Git Commits on MacOS *Last updated March 13, 2024* This Gist explains how to sign commits using gpg in a step-by-step fashion. Previously, krypt.co was heavily mentioned, but I've only recently learned they were acquired by Akamai and no longer update their previous free products. Those mentions have been removed. Additionally, 1Password now supports [signing Git commits with SSH keys](https://developer.1password.com/docs/ssh/git-commit-signing/) and makes it pretty easy-plus you can easily configure [Git Tower](https://www.git-tower.com/blog/1password-ssh-tower/) to use it for both signing and ssh. For using a GUI-based GIT tool such as Tower or Github Desktop, follow the steps [here](3-GUI-git-signing.md) for signing your commits with GPG. There has been a number of comments on this gist regarding some issues around the pinentry-program and M1 Macs. I've finally gotten a chance to try things out on an M1 and I've updated the documentation in `2-using-gpg.md` to reflect my findings.
