OpenPGP SSH access with Yubikey and GnuPG

NB: This document describles a 'Old-School' way of using Yubikey with SSH

Modern OpenSSH has native support for FIDO Authentication. Its much simpler and should also be more stable with less moving parts. OpenSSH also now has support for signing arbitary files witch can be used as replacement of gnupg. Git also supports signing commits/tags with ssh keys.

Pros of FIDO

  • Simpler stack / less moving parts
  • Works directly with ssh, ssh-add and ssh-keygen on most computers
  • Simpler
  • Private key can never leave the FIDO device

Cons of FIDO

Tools Engineer Checklist

This list is provided as a guide for tools engineers of all skill levels looking for jobs in the game industry. It's meant as a guide to topics that should be pursued broadly in order to be well spoken in an interview. I doubt any hiring manager requires deep knowedge across every topic, but an ideal candidate would be somewhat knowledgable (aware of its existence if asked directly) with all topics here.

Each list of bullets increases in difficulty, so later bullets are more applicable to senior (or even director) level candidates.

Good luck.
