How to set up git to use the GPG Suite

GPG and git on macOS

Setup

No need for homebrew or anything like that. Works with https://www.git-tower.com and the command line.

  1. Install https://gpgtools.org -- I'd suggest to do a customized install and deselect GPGMail.
  2. Create or import a key -- see below for https://keybase.io
  3. Run gpg --list-secret-keys and look for sec, use the key ID for the next step
  4. Configure git to use GPG -- replace the key with the one from gpg --list-secret-keys
