ZX2C4's pass in Windows

Recently I've migrated to pass, but on its website there is no Windows installation guide. One of the things that helped me writing this guide is this blog post.

Prerequisites

• git
• If you want to integrate with Firefox, Python 3 (If you're running Windows 10 and you don't have Python installed yet you just need to open the command prompt and type python followed by Enter. The Microsoft store will open and from there you can download Python)
• GPG4Win. No, the gpg bundled with git doesn't work.

How do we put this together?

1. Import the GPG keys into Kleopatra (GPG keystore for Windows)
2. Make sure you can access the repo with git and that you don't have incompatible path names for Windows in it.
3. Download gopass. From there you will download a zip file. You only need the exe file inside it.
4. Check your PATH by typing PATH inside cmd
   1. If there's a folder inside your user folder in it, place the gopass.exe in it and call it pass.exe.
   2. Otherwise, create a bin folder and add it to the PATH by:
      • Creating a bin folder somewere
      • In explorer.exe, right click This Computer > Properties
      • Click Advanced system settings (or similar)
      • Click Environment variables
      • Under User variables, select Path, then click Edit
      • Click Add, then type the path to the bin folder
      • Click OK twice
      • Logout and log back in
      • Place the downloaded gopass.exe in the bin folder and name it pass.exe
5. Inside your prompt/shell, type pass clone repo_URL
6. Now, if yoy type pass ls you should see all your passwords
7. You should have a working pass installation. While gopass is almost a drop-in replacement for pass, not all commands work the same. For example, pass show in gopass requires a website.

Install a GUI

1. Download QtPass
2. Right click the msi file and run it as administrator.
3. If you're lucky, the program will open. If it doesn't, open regedit.exe and go to Computer\HKEY_CURRENT_USER\SOFTWARE\IJHack\QtPass. Check that the variables reference correct executables and the password store.
4. At this point, you should have a working GUI.

Integrate with Firefox

1. Go to this repo and install the host application.
2. Go to Computer\HKEY_CURRENT_USER\SOFTWARE\Mozilla\NativeMessagingHosts\passff in regedit.exe and open the specified path. In my case the path is %appdata%\passff.
3. The passff.py file is made to work with the standard pass executable, so it will fail miserably in our case.
4. I've edited line 63 and replaced show with ls. Here is my modified version.
5. Now you can install the extension and, after restarting Firefox, your passwords should work.
6. There's an option in about:addons that autofills your passwords that you can enable by opening passff's options.
