GPG and git on macOS

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

$ git config --global gpg.program /usr/local/MacGPG2/bin/gpg2
$ git config --global user.signingkey A6B167E1 
$ git config --global commit.gpgsign true
