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 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.

	enum ArrayBuilder<OutputModel> {
	static func buildEither(first component: [OutputModel]) -> [OutputModel] {
	return component
	}

	static func buildEither(second component: [OutputModel]) -> [OutputModel] {
	return component
	}

	# Set bash script to exit immediately if any commands fail
	set -e

	This is a concept re-implementation of the @Binding and @State property wrappers from SwiftUI

	The only purpose of this code is to implement those wrappers myself
	just to understand how they work internally and why they are needed,

	⚠️ This is not supposed to be a reference implementation nor cover all
	subtleties of the real Binding and State types.
	The only purpose of this playground is to show how re-implementing
	them myself has helped me understand the whole thing better
