Setting up your own self-hosted chat on the Tor network has never been this easy. Guests open your .onion link in Tor Browser, no port forwarding, no cloud account, and no complicated setup. OffCode Tor Chat is designed to make secure Tor Hidden Service hosting simple.
Messages are encrypted in-browser with WebCrypto AES-256-GCM (PBKDF2-v2, 600k iterations) before reaching the server, ChatServer relays and stores ciphertext only. Password rooms use separate KDF domains so the host cannot derive the key; open rooms are public encrypted channels.
Host with Server Manager on Windows, or headless Docker (ChatServer + Tor HS). Password rooms are server-blind E2EE (the host cannot derive the room key). Open rooms still encrypt in the browser, but the key is derived from the room id: intentional public channels. Hidden rooms stay off the public list and use invite links; add a password for private E2EE. Creators get Settings for close joins, slow mode, lock later, and delete room, plus a Profile recovery code (My rooms for hidden). Required message TTL, E2EE attachments, and optional Full Vanguards complete the stack.
