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
