Encrypted Volumes in WSL2

Description

This is a quick guide on how to setup dm_crypt under WSL2 for working with encrypted volumes. I use an encrypted volume to store things like password recovery codes and 2nd factor backup codes etc. I recently switched over to using WSL2 and wanted to figure out how to enable this functionality there. This is the distilled howto for getting it to work.

Guide

First thing you have to do is create a custom WSL2 kernel. Inside your already installed and running WSL2 (ubuntu) installation:

Install some required packages.

	Add the toolchain/test PPA
	sudo add-apt-repository ppa:ubuntu-toolchain-r/test
	sudo apt-get update
	sudo apt-get install g++-4.8
	sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-4.8 50

	If you ever want to update symlinks for a future version:
	sudo rm /usr/bin/g++
	sudo ln -s /usr/bin/g++-4.XXX /usr/bin/g++
