DisCrypt - End-to-End Encryption for Discord

Secure peer-to-peer messaging on Discord using client-side encryption. Messages and files remain encrypted end-to-end, even if your Discord account is compromised.

How It Works

  1. Add a peer by their Channel ID (DM channel) and public keys
  2. Messages auto-encrypt on send, auto-decrypt on receive, message edition is well handled
  3. Only you and the intended recipient can read your messages
  4. Encryption verified with color coding (blue = sent, green = received)

Features

  • End-to-end encryption using X25519 ECDH + XSalsa20-Poly1305 (TweetNaCl)
  • Automatic message encryption/decryption
  • Encrypted file attachments with Ed25519 signature verification
  • Message editing support
  • Reply handling for encrypted messages
  • Peer management UI with key storage
  • Works in DMs and group channels

Security Model

Threat Model: Protects against message interception if your account is compromised.

Does NOT protect against:

  • Private key compromise (if your computer is compromised)
  • Man-in-the-middle attacks during key exchange (manually exchange keys via secure channel)
  • Message metadata (timestamps, message count, presence)

Implementation Details:

  • Private keys stored in browser localStorage only
  • Uses NaCl.box (X25519 ECDH) for asymmetric encryption
  • Ed25519 signatures for file authenticity verification
  • Sender/recipient public keys included in message format for verification

Limitations

  • No forward secrecy (compromise of keypair compromises all messages)
  • No built-in key exchange protocol (manual key sharing required)
  • Private keys stored in plaintext in localStorage
  • File upload MIME type spoofing (.png wrapper) for CORS bypass

  • [ ] Key import/export with password protection
  • [ ] Code refactor for maintainability
  • [ ] Link preview support
  • [ ] Better media handling after decryption
