- Integrate a Dart/Go encryption library (e.g.,
libsignal, olm, or libsodium)
- 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
