Hi everyone, I'm Chris Wanstrath. | |
When Jeremy asked me to come talk, I said yes. Hell yes. Immediately. But | |
then I took a few moments and thought, Wait, why? Why me? What am I supposed | |
to say that's interesting? Something about Ruby, perhaps. Maybe the | |
future of it. The future of something, at least. That sounds | |
keynote-y. | |

FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.

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 and makes it pretty easy-plus you can easily configure Git 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 for signing your commits with GPG.
