Host with Server Manager on Windows, or headless Docker (ChatServer + Tor HS). Password rooms are server blind E2EE, so the host cannot derive the room key. Open rooms still encrypt in the browser, but the key is derived from the room ID, creating intentional public channels. Hidden rooms stay off the public list and use invite links. Add a password for private E2EE. Creators get Settings for closed 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.

Server Manager is the host-side control panel: it starts and stops ChatServer plus a Tor v3 Hidden Service, shows the .onion URL to share, optionally enables Full Vanguards, and lets you administer rooms and storage. The host never receives plaintext from clients; password-room keys stay in browsers. Open-room keys are derivable from the room id by design.

Start ChatServer first (Production, waits for /api/health), then enable Tor Copy and share the published .onion URL

Optional Full Vanguards checkbox (Python + Stem) for long-lived HS hardening

Live room list (room id, locked flag, online count only, no message content)

Remove a selected room in realtime: connected users are forced back to the lobby; ciphertext for that room is deleted with secure_delete + VACUUM

Remove SQL data: securely overwrites (then deletes) the SQLCipher DB, WAL/SHM, and db.key.dpapi; optional checkbox also wipes Tor Hidden Service keys (.onion identity)

Generate new address: securely wipes HS keys and publishes a new .onion (chat DB unchanged)

ChatCrypt features and specs

  • End-to-End Encryption
    ChatCrypt provides end-to-end encryption, ensuring that messages are only readable by the communicating parties and not by any intermediaries.
  • User Anonymity
    The service allows users to maintain privacy and anonymity since it does not require personal information for account creation.
  • No Data Retention
    ChatCrypt does not store messages on its servers, minimizing data retention risks and protecting user privacy.
  • Cross-Platform Support
    It supports multiple platforms, allowing communication across different devices seamlessly.

Possible disadvantages of ChatCrypt

  • Limited Features
    Compared to other messaging services, ChatCrypt may offer fewer features such as media sharing or integrations with other apps.
  • User Interface
    The user interface might not be as polished or intuitive as other more mainstream messaging applications, which might affect user experience.
  • Reliability
    As a less mainstream service, there may be concerns about the long-term reliability and support for ChatCrypt.
  • Exposure Risk
    Despite strong encryption, users could still be vulnerable to exposure if encryption keys are mismanaged or if their device is compromised.

  • Full Vanguards Guard-Discovery Protection
    A standard Tor Hidden Service chooses its entry (guard) nodes randomly on every circuit build. Over time a network-level adversary can watch which relays the server connects to and gradually narrow down the real server IP. This is called a guard-discovery attack and is especially dangerous for long-lived hidden services.
  • Encryption
    WebCrypto AES-256-GCM; PBKDF2-v2 domains at 600 000 iterations (torchat-join-v2 / torchat-e2ee-v2 locked = server-blind; torchat-open-v2 open = public key material). Envelopes: pbkdf2-v2 / ecdh-hybrid-v1
  • XSS hardening
    No user innerHTML; messages and room ids via textContent / createElement
  • ECDH + safety number
    1:1 hybrid ECDH; safety number from sorted SPKI pubs (3ร—5 decimal); Mark verified / TOFU change warning (sessionStorage)
