Use simplediscordcrypt in web console or on discord

simplediscordcrypt.js

  // contentWindow property will return a new Window object with
  // a freshly created `localStorage` property. Once we obtain the
  // property descriptor, we can disconnect the <iframe> and let it

  // anything from its origin realm to work**.

// -- temporary hack to get simplediscordcrypt working in discord desktop console --
// By Scoder12

// Discord CSP allows fetching from 127.0.0.1:* so we can host the script locally and
//  fetch and eval it from the console

// Setup:
// curl -sSLo main.js https://gitlab.com/An0/SimpleDiscordCrypt/-/raw/master/SimpleDiscordCrypt.user.js
// curl -sSlo blacklist.txt https://gitlab.com/An0/SimpleDiscordCrypt/raw/master/blacklist.txt
// Replace BLACKLIST_URL value with http://127.0.0.1:35181/blacklist.txt

// Setup part 2 Host:
// place the following in server.py
/*
#!/usr/bin/env python3
from http.server import HTTPServer, SimpleHTTPRequestHandler, test
import sys

class CORSRequestHandler (SimpleHTTPRequestHandler):
    def end_headers (self):
        self.send_header('Access-Control-Allow-Origin', 'https://discord.com')
        SimpleHTTPRequestHandler.end_headers(self)

if __name__ == '__main__':
    test(CORSRequestHandler, HTTPServer, bind="127.0.0.1", port=int(sys.argv[1]) if len(sys.argv) > 1 else 8000)
*/
// python3 server.py 35181

// now, in discord press ctrl+shift+i, then click console, and paste this entire file in
