Possible disadvantages

• Limited Advanced Features
  Compared to other screen recording software, ScreenStudio may lack some advanced features such as annotations or detailed editing capabilities.
• Performance Issues
  Users may occasionally experience performance issues or bugs, which can be expected from open-source and less-commercial software options.
• Lack of Customer Support
  As an open-source project, there may be limited official customer support, relying on community forums for assistance.

• Ciphertext storage
  SQLCipher database under LocalAppData (Windows) or Docker volume. DPAPI / env key. Parameterized queries. Plaintext is never written to disk.
• Close room to new members
  blocks all joins (including invites); members stay
• Slow mode
  Send cooldown 1 min … 4 h (applies to everyone, including creator)
• Delete this room
  Same wipe path as Server Manager room delete
• Creator recovery code
  Binds rooms you create; My rooms lists hidden; Copy / Restore
• Rooms, invites & TTL
  Open, password-protected, and/or hidden rooms with invite links and required per-message lifetime.
• Server manager
  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 Locks CORS to your onion: TORCHAT_ALLOWED_ONION on start + live POST /api/admin/cors-onion (no ChatServer restart) 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) Point at your ChatServer project path and load/save host config as needed
• 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 (3×5 decimal); Mark verified / TOFU change warning (sessionStorage)
