GPG, SSH Auth with Keybase

Installing requirements:

sudo pacman -S kbfs keybase keybase-gui micro

If you are having problems with gpg-agent as ssh agent mode, restart gnupg from scratch (export your important keys first)

rm -rf ~/.gnupg

Login to Keybase using the GUI or keybase login. Now import private key and public keys from keybase:

keybase pgp export --secret | gpg --allow-secret-key-import --import
keybase pgp export | gpg --import

Setup GPG Agent:

micro ~/.gnupg/gpg-agent.conf

With the below contents:

enable-ssh-support

default-cache-ttl-ssh 10800
max-cache-ttl-ssh 10800

pinentry-program /usr/bin/pinentry-gnome3

Setup PAM environment as extra:

micro ~/.pam-environment

With the below contents:

SSH_AGENT_PID	DEFAULT=
SSH_AUTH_SOCK	DEFAULT="${XDG_RUNTIME_DIR}/gnupg/S.gpg-agent.ssh"

Add your keys to SSH control file, that keeps the "authorized" keys to use by the emulated SSH agent:

ls ~/.gnupg/private-keys-v1.d/ | sed s/.key// >> ~/.gnupg/sshcontrol

Now logout and login again, or event better, reboot your machine. Check your SSH keys with:

ssh-add -l

If you are getting errors like error fetching identities: agent refused operation then you need to remove offending keys that are not Authorization keys. You can check them with:

gpg --list-keys --with-keygrip

Then comment out the keys with # or remove auth with ! at ~/.gnupg/sshcontrol:

micro ~/.gnupg/sshcontrol````
