YubiKey 4 series GPG and SSH setup guide

Written for fairly adept technical users, preferably of Debian GNU/Linux, not for absolute beginners.

You'll probably be working with a single smartcard, so you'll want only one primary key (1. Sign & Certify) and two associated subkeys (2. Encrypt, 3. Authenticate). I've published a Bash function which automates this slightly special key generation process.

Please include a repro

You probably arrived here because of a curt message in response to an issue you filed on a repo that I contribute to. Sorry about that (particularly if you filed the issue long ago and have been waiting patiently for a response). Let me explain:

I work on a lot of different open source projects. I really do like building software that makes other people's lives easier, but it's crazy time-consuming. One of the most time-consuming parts is responding to issues. A lot of OSS maintainers will bend over backwards to try and understand your specific problem and diagnose it, to the point of setting up new test projects, fussing around with different Node versions, reading the documentation for build tools that we don't use, debugging problems in third party dependencies that appear to be involved in the problem... and so on. I've personally spent hundreds of hours of my free time doing these sorts of things to try and help people out, because I want to be a responsible maintainer and I

I have a meeting with 100’s of participants and we wanted to run a simple impromptu “show of hands” poll without using the specific polling feature. All I needed was a list of all the attendees with their hand raised at a certain point in time…

Wireguard and iptables restrictions for multiple users

If you don't know what Wireguard is, well, you should. It's fast, easy to setup and highly configurable. We will configure Wireguard for multiple users with various restrictions using iptables.

Assumptions

This should fit most setups (not mine though 😉)
