End‑to‑end encryption (E2EE) #23
Description
Implement true end‑to‑end encryption using the Signal protocol (or a compatible library) for one‑to‑one and group chats.
- Integrate a Dart/Go encryption library (e.g.,
libsignal,olm, orlibsodium) - Perform key exchange upon first interaction (X3DH or similar)
- Encrypt all message content on the sender’s device before it leaves the app
- Decrypt only on the recipient’s device(s)
- The server must never have access to plaintext keys or message content
- Handle key rotation, device changes, and session resets
This is a critical privacy feature. Extensive testing and security review required.
