    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.

                Deploy to `gh-pages` from a `dist` folder on the master branch. Useful for use with [yeoman](http://yeoman.io).
              
          
    Deploying a subfolder to GitHub Pages

Sometimes you want to have a subdirectory on the master branch be the root directory of a repository’s gh-pages branch. This is useful for things like sites developed with Yeoman, or if you have a Jekyll site contained in the master branch alongside the rest of your code.
For the sake of this example, let’s pretend the subfolder containing your site is named dist.
Step 1

Remove the dist directory from the project’s .gitignore file (it’s ignored by default by Yeoman).
