Tutorial for installing a 64-bit Arch Linux ARM system on the Raspberry Pi 4B, with an encrypted root filesystem, and the option to remotely unlock it via a pre-boot SSH daemon.

Arch Linux ARM 64 on Raspberry Pi 4B With Full Disk Encryption And SSH Unlock: 2022 Edition

There are multiple ways to get a full disk encrypted arch linux system on raspberry. In this tutorial, we will install a 64-bit arch linux armv8 system, using dropbear as ssh server for remote pre-boot unlocking of the root filesystem. However, it will still be possible to unlock and use the pi as usual, with a keyboard and monitor. We will also create an unencrypted partition in the installation process, usable as a rescue system.

For different setup options, see the end of the document.
