Install gnupg.

Generate a new gpg key just for authentication:

gpg2 --expert --edit-key 024C6B1C84449BD1CB4DF7A152295D2377F4D70F

Toggle options S, E, and A until the following output:

Current allowed actions: Authenticate

Add ssh to the gpg key agent.

echo enable-ssh-support >> ~/.gnupg/gpg-agent.conf

This won't take effect until you restart the gpg agent, so kill it:

gpgconf --kill gpg-agent

gpgconf --launch gpg-agent

Use 2048 (or whatever) bits, save, and exit.

Add this to your ~/.bash_profile:

export SSH_AUTH_SOCK=$(gpgconf --list-dirs agent-ssh-socket)

source ~/.bash_profile

Find the ssh key's keygrip with:

gpg -k --with-keygrip

It's the one with [A] next to it. Add it to ~/.gnupg/sshcontrol.

echo 1P0P6SA7S07Q8198414P126OR0514R3R8Q1389SP > ~/.gnupg/sshcontrol

Confirm it's added:

ssh-add -l
