Signing your Git Commits on MacOS

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.

Capybara configuration connecting to selenium server for testing with a remote browser (pretty useful in Vagrant)
# SELENIUM_SERVER is the IP address or hostname of the system running Selenium
# Server, this is used to determine where to connect to when using one of the
# selenium_remote_* drivers
SELENIUM_SERVER = "10.10.11.1"
# SELENIUM_APP_HOST is the IP address or hostname of this system (where the
# tests run against) as reachable for the SELENIUM_SERVER. This is used to set
# the Capybara.app_host when using one of the selenium_remote_* drivers
SELENIUM_APP_HOST = "10.10.11.2"
