🔒 Major Encryption Fixes

This release fixes critical encryption bugs that were causing "MAC verification failed" errors and preventing users from viewing their conversation history.

✨ What's New

Message Cache System

  • Implemented encrypted message cache for persistent conversation history
  • Messages are cached with password protection using ChaCha20-Poly1305
  • View your entire conversation history without decryption issues

Bug Fixes

  • Fixed Session Establishment: Corrected X3DH key agreement to use signed prekey properly
  • Fixed Ratchet Synchronization: Messages can now be viewed multiple times
  • Sent Messages Visible: Your own sent messages now appear in conversations
  • Removed Unused Code: Cleaned up wasteful ephemeral key generation

New Features

  • Cache management UI in security menu
    • View Cache Status (message count and size)
    • Clear Message Cache option
  • Automatic session establishment from incoming messages
  • Better error messages for encryption failures

🔄 Upgrade Notes

This release is backward compatible with existing sessions and messages. The message cache will be built gradually as you view conversations.
