                Signing git commits with SSH key
              
          
    To enable signing commits using an ssh key:

git config --global user.signingkey "your ssh public key"
git config --global gpg.format ssh
(OPTIONAL: Use 1PW for sharing the ssh key) git config --global gpg.sshprogram /Applications/1Password.app/Contents/MacOS/op-ssh-sign
git config --global commit.gpgsign true

To have git log show signature checks:

git config --global log.showSignature true
git config --global gpg.ssh.allowedSignersFile $HOME/.gitallowed_signers
create $HOME/.gitallowed_signers and put in a line such as this (with a name and the public key): name ssh-ed25519 WEPOFJEWOI123/asdQW

                Sign git commits with ssh key
              
          
1Password makes it easy to manage ssh keys, providing an ssh agent of course. I like this integration, although it's not needed (ssh-add)
git allows to sign commits using gpg, but also using ssh keys (which makes it even easier IMO)
To enable signing via ssh, add these config entries:
git config --global user signingkey "‹your ssh public key›"
git config --global gpg. format ssh
git config --global gpg.ssh.program /Applications/1Password.app/Contents/MacOS/op-ssh-sign
git config --global commit.gpgsign true
To have git log show signature checks:
git config --global log. showSignature true
git config --global gpg.ssh.allowedSignersFile $HOME/.gitallowed_signers
