I've decided I don't want to keep an ssh key on my traveling laptop, but I still need to be able to authenticate to a number of hosts (and expecially gpg repositories). I also have an OpenPGP smartcard (from the FSFE). A plan is starting to form.

There are a number of guides available, but many of those are obsolete; the following pages are from this decade:

• Using GnuPG (2.1) for SSH authentication
• Using GnuPG for SSH authentication (from the same author, using GnuPG 2.0, includess still current notes on using a smartcard)
• How to use authentication subkeys in gpg for SSH public key authentication
• SSH authentication with your PGP key

I've had some success from outside X, now I need to find out where I should disable ssh-agent from starting every time a start an X session, so that gpg-agent can take its place.
