Cybersecurity Projects Python SolidJS License: AGPLv3 Docker Signal Protocol

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.

[!TIP] This project uses just as a command runner. Type just to see all available commands.

Install: curl -sSf https://just.systems/install.sh | bash -s -- --to ~/.local/bin

Stack

Backend: FastAPI, PostgreSQL + SQLModel, SurrealDB, Redis, Alembic

Frontend: SolidJS 1.9, TypeScript, Vite 6, Tailwind CSS v4
