This useful bits of envoy + gpg-agent distilled into a standalone
project, usable without running envoyd.
To use this, create a systemd --user service that looks like this:
[Service]
Type=forking
ExecStart=/usr/bin/gpg-agent --daemon --enable-ssh-support
[Install]
WantedBy=multi-user.target
Then make sure you have the following in your environment (I use
~/.pam_environment):
SSH_AUTH_SOCK=/home/simon/.gnupg/S.gpg-agent.ssh
Then you can use gpg-exec to the same effect as envoy-exec.
