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.

  ## SUMMARY ##

# Let `a` be the nested array and `aref` the multidim array we want to recreate:
julia> flatten(x::Array{<:Array,1})= Iterators.flatten(x)|> collect|> flatten
flatten (generic function with 1 method)

julia> flatten(x::Array{<:Number,1})= x
flatten (generic function with 2 methods)

julia> reshape(flatten(a), (4,4,3)) == aref

# OBJECTIVE:  Install Arch Linux with encrypted root and swap filesystems with an ENCRYPTED BOOT and boot from UEFI.  We will
also decrypt and mount our entire encrypted system using a single LUKS passphrase entry.

# Note:  This method supports both dedicated Arch installs and those who wish to install Arch on a multi-OS-UEFI booting system.

# External USB HDD/SSD Installers Notes:  Encrypted Arch installs can be booted and run from an external USB HDD or SSD, but
# only when the installation is correctly set up.  There are several necessary changes to my standard procedure you'll want
# to make during the install process.  Read my External USB HDD/SSD Installation section below before proceeding.
