Methods of Signing with a GPG Key on MacOS

Last updated September 21, 2022

This Gist explains how to do this 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.

For using a GUI-based GIT tool such as Tower or Github Desktop, follow the steps here 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.

Make it real

Ideas are cheap. Make a prototype, sketch a CLI session, draw a wireframe. Discuss around concrete examples, not hand-waving abstractions. Don't say you did something, provide a URL that proves it.

Ship it

Nothing is real until it's being used by a real user. This doesn't mean you make a prototype in the morning and blog about it in the evening. It means you find one person you believe your product will help and try to get them to use it.

Do it with style
