linkRunning charm-crypto in Windows

For all intents and purposes, we will be using Windows Subsystem for Linux (WSL) to make this work. Any attempt I made to make this run natively has been frustratingly unsuccessful. With that being said, let us begin.

linkInstall Windows Subsystem for Linux (WSL)

This guide will only cover installation of WSL 1. WSL 2 offers a lot of performance improvements so do check it out also. Full documentation here.

linkEnable WSL

  1. Open PowerShell as Administrator and run:
    1linkdism.exe /online /enable-feature /featurename:Microsoft-Windows-Subsystem-Linux /all /norestart

  2. Restart your machine.

linkInstall Ubuntu 20.04 LTS

You can always select another distribution if you like.

  1. Go to Ubuntu 20.04
  2. Select 'Get'. If a prompt asks you to open the Microsoft Store, just click 'Open'.
  3. Select 'Install'
  4. Select 'Launch'. This will take a little bit of time but all future launches should take less than a second. You will then need to create a user account and password for your new Linux distribution.
  5. You now have access to an Ubuntu terminal. Just type 'Ubuntu' in your Start menu and click the app.

Create a folder named charm_root in your Windows desktop. This will just simplify things and make the guide easier to follow.

  2. Extract PBC files. In your Ubuntu terminal, run:
