调研方向

Start with the group E2EE design note, which this issue says is a blocker, then read mobile/lib/services/signal_service.dart and mobile/lib/services/sqlite_signal_store.dart for sender key storage. Trace message handling through mobile/lib/core/message_envelope.dart and mobile/lib/controllers/chat/. Done means group sender keys are distributed and rotated on membership changes, encryption and decryption work, the notice and group info screen are updated, and round-trip and rotation tests pass.

描述

area: e2ee area: mobile blocked difficulty: hard enhancement

Part of the group E2EE epic. Blocked by the design note.

What to do

  • Create and distribute your sender key per group (GroupSessionBuilder), and process incoming distribution messages.
  • Encrypt and decrypt group messages with GroupCipher.
  • Rotate keys on membership changes, as the design describes.
  • Update the in-app notice ("Group messages are not end-to-end encrypted yet") and the group info screen.
  • Tests for encrypt/decrypt round-trips and rotation.

Where to look

mobile/lib/services/signal_service.dart, mobile/lib/services/sqlite_signal_store.dart (SenderKeyStore), mobile/lib/core/message_envelope.dart, mobile/lib/controllers/chat/.
