supabase_chat_e2ee 0.1.0

Opt-in end-to-end encryption for supabase_chat using the Signal Protocol (libsignal_protocol_dart): prekey distribution over Supabase and an encrypted room decorator. The server only ever sees ciphertext.

0.1.0

• Initial release.
• Opt-in end-to-end encryption for supabase_chat via the Signal Protocol (libsignal_protocol_dart): the server only ever stores ciphertext.
• E2eeIdentity (generate/restore, BYO-persistable Signal store) and E2eeManager (sessions, per-recipient encrypt, decrypt).
• DeviceKeyBundle + PreKeyDirectory (SupabasePreKeyDirectory / InMemoryPreKeyDirectory) for X3DH prekey distribution over Supabase, with atomic server-side one-time-prekey consumption.
• EncryptedChatRoom decorator: verify-first encrypt-on-send / decrypt-on-receive for 1:1 rooms.
• Safety numbers + strict requireVerified mode (MITM protection) and IdentityChangedException (key-change rejection).
• SQL migration for device_keys / one_time_prekeys (+ claim_one_time_prekey RPC) and messages.encrypted.
• Licensed GPL-3.0 (this package links the GPL libsignal_protocol_dart), so the pub.dev license matches the obligation you take on. Closed-source apps should use supabase_chat_seal (MIT) instead.
• Ships an EncryptedChatView Flutter recipe in the README (pairs the MIT supabase_chat_widgets widgets with this package in your app).
