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)

Possible disadvantages of Retro

  • Limited Free Version
    The free version of Retro has limited features compared to the premium offering, which might restrict its usability for teams that are unable to invest in paid plans.
  • Learning Curve for New Users
    While the interface is user-friendly, new users may still require some time to familiarize themselves with all the features and functionalities available.
  • Dependence on Internet Connection
    As a web-based application, Retro requires a stable internet connection to function, which could be problematic in areas with poor connectivity.
  • Potential for Feature Overload
    The wide array of features might be overwhelming for smaller teams or those new to retrospective tools, leading to underutilization of the available functionalities.
  • Data Privacy Concerns
    As with any online tool, there might be concerns regarding the privacy and security of data entered into the platform, particularly for sensitive or proprietary information.

  • 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
