🔐 BrailleCrypt for Discord

An automatic end-to-end encryption tool for Discord desktop chat. Encrypts your messages using AES-256-GCM and displays them as Braille characters — readable only by friends with the same key.

⚠️ Disclaimer: This tool is a Proof of Concept. Using modified clients or automated tools may violate Discord's Terms of Service. Use at your own risk. This project is for educational purposes only.

🔥 Features

• End-to-End Encryption: Messages are encrypted locally before they ever reach Discord's servers.
• Automatic Decryption: Incoming messages from friends with the same key are instantly decrypted.
• Invisible Integration: Runs as a separate process connecting via Chrome DevTools Protocol (CDP) — no Discord file modifications.
• Stealthy: Encrypted text is encoded as Braille Unicode to blend in visually and bypass some spam filters.
• Secure Defaults: Uses AES-256-GCM and PBKDF2 (600k iterations) for strong security.

🚀 Quick Start

Prerequisites

• Node.js (v14 or newer)
• Discord Desktop Client (Windows)

Installation

1. Clone the repository:

   git clone https://github.com/KenzoNight/BrailleCrypt-For-Discord.git
   cd BrailleCrypt-For-Discord

2. Install dependencies:

   npm install

3. Configure (Optional): Copy the example config if you want to save your preferences:

   cp config.example.json config.json

   Tip: You can edit config.json to set a default key, but be careful not to commit it!

Usage

Launch everything automatically:

node main.js --key "your-secret-password"

This will kill any running Discord processes and relaunch it with the necessary debug flags.

Or connect to an already-running instance:

1. Start Discord with: Discord.exe --remote-debugging-port=9222
2. Run the tool:

   node main.js --key "your-secret-password" --no-launch --port 9222

🛠️ Configuration

You can configure the tool via config.json or CLI arguments.

setting	description	default
encryptionKey	The shared secret used for AES-256-GCM.	"" (prompts if empty)
debugPort	Local port for CDP connection. 0 = random.	0
pbkdf2Iterations	Rounds of hashing for key derivation.	600000
messagePrefix	The characters marking the start of a message.	⠓⠑

CLI Arguments:

• --key, -k: Set the encryption key.
• --port, -p: Set text debug port.
• --no-launch: Attach to existing Discord process.

🔒 Security Model

What is Encrypted?

• Message Content: The actual text you type is encrypted using AES-256-GCM.
• Integrity: The GCM tag ensures messages cannot be tampered with without detection.

What is NOT Encrypted (Metadata)?

• Sender/Receiver: Discord knows who you are messaging.
• Timestamps: Discord knows when you are messaging.
• Message Length: While Braille encoding obfuscates exact length, the approximate size matches the ciphertext.

Local Security

• The tool listens on 127.0.0.1 (localhost) only.
• Default behavior uses a randomized port each time to prevent local port scanning.
