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.

Hope this will stay relevant for longer than just 2021. This guide will focus mostly on things you shouldn't overlook and will harshly prioritise assuming that you're running on recent hardware. EFI and all that.

Always refer to the official guide in case of doubt.

First things first

One important thing first: the environment you will encounter on the live image is very different from what you'll end up installing, some things are significantly easier there: e.g. wifi tools come pre-installed, the default shell is a pimped zsh with nice completions, and so on. We'll keep this

Arch Linux Full-Disk Encryption Installation Guide

This guide provides instructions for an Arch Linux installation featuring full-disk encryption via LVM on LUKS and an encrypted boot partition (GRUB) for UEFI systems.

Following the main installation are further instructions to harden against Evil Maid attacks via UEFI Secure Boot custom key enrollment and self-signed kernel and bootloader.

Preface

You will find most of this information pulled from the Arch Wiki and other resources linked thereof.

Note: The system was installed on an NVMe SSD, substitute /dev/nvme0nX with /dev/sdX or your device as needed.

Scrolling in the Linux Console (ttys)

Scroll Up: Shift + Page Up

Scroll Down: Shift + Page Down

The scrollback buffer is quite short in Linux consoles, and the scrollback buffer is not stored on system RAM, but VGA RAM. The buffer is also lost on switching ttys. There was a kernel patch to fix this, but not yet accepted.
