WASM Accelerated Solver Module for Vulcan

Thanks to Rust and Web Assembly you can now pass Vulcan Proof-of-Work captcha about ~20 times faster (from 5 s to 220 ms on i7-12700KF), and even more on mobile devices!

🚀 Features

• Speed: Drastically reduces login time by accelerating the PoW calculation.
• Privacy: Runs entirely locally in your browser.
• Compatibility: Works on Chromium-based browsers (Chrome, Brave, Vivaldi) and Firefox.

📦 Installation

Manual Build

To build the extension from source you need to:

1. Install Rust, wasm-pack and web-ext
2. Run wasm-pack build --target web
3. Run web-ext build

Pre-built

Simply download a ready build from the releases page.

🔧 How to use

To add the extension to your browser:

1. Firefox:
   • Open about:debugging#/runtime/this-firefox
   • Click on "Add temporary extension"
   • Select manifest.json from your unpacked .zip.
2. Chromium:
   • Open chrome://extensions/
   • Turn on "Developer mode" (top right corner)
   • Click on "Load unpacked"
   • Select your unpacked folder.

🛠️ How it works

This extension intercepts the Proof-of-Work challenge from EduVulcan and offloads the heavy calculation to a WebAssembly module compiled from Rust. This is significantly faster than the default JavaScript implementation provided by the website.
