End-to-end encrypted peer-to-peer chat with Signal Protocol (Double Ratchet + X3DH) and WebAuthn/Passkey authentication.
This is a quick overview — security theory, architecture, and full walkthroughs are in the learn modules.
What It Does
- Double Ratchet protocol (Signal) with X3DH key exchange for end-to-end encryption
- WebAuthn/Passkey authentication with discoverable credentials and multi-device support
- Forward secrecy and break-in recovery with out-of-order message handling
- Real-time WebSocket messaging with SurrealDB live queries
- Presence tracking, typing indicators, read receipts, and heartbeat keep-alive
- Alembic database migrations with full test suite
Quick Start
docker compose up -d
Visit http://localhost:8080 to open the application.
