- Eliminated unsafe global state (window.*)
- Added DoS protection with MessageSizeValidator
- Added race condition prevention with AtomicOperations
- Added rate limiting (10 files/minute)
- Added secure memory management with SecureMemoryManager
- Wrapped handleFileChunk in atomic operations
- Updated all methods with security enhancements
- File Transfer Integration: Refactored file transfer system initialization with better error handling and automatic retry mechanisms
- Message Filtering: Added comprehensive message filtering system to prevent file transfer and system messages from appearing in chat UI
- Callback System: Simplified file transfer callback system - removed progress notifications from chat to reduce noise
- System Message Deduplication: Implemented notification flags to prevent duplicate system messages (verification, security upgrades, etc.)
- Error Handling: Enhanced error handling with graceful fallbacks instead of throwing exceptions that could break connections
- UI Message Delivery: Added `deliverMessageToUI()` method with built-in filtering for system/file messages
- DataChannel Event Handling: Improved onmessage handler with early filtering for file transfer messages
- Global Integration: Better integration with global file transfer system (`window.fileTransferSystem`)
- Connection Stability: Removed aggressive reconnection attempts that could cause session closure
- Debug Logging: Enhanced debug logging for better troubleshooting
- File transfer messages now bypass chat UI entirely
- System messages are deduplicated using internal flags
- Better separation of concerns between WebRTC and file transfer systems
- More robust initialization sequence with proper cleanup
- Improved message routing and processing pipeline
- Fixed duplicate system notifications
- Resolved file transfer message leakage into chat
- Improved connection state management
- Better handling of initialization race conditions
- Reworked the core logic for encrypting and decrypting files exchanged between users
- Improved key derivation and session handling for file chunks
- Enhanced integrity checks to prevent tampering and replay attacks
- Work in progress: adding hardened encryption schemes and conducting fault-tolerance testing
Added an early implementation of secure file transfer using chunk-based encryption.
Files are split into encrypted chunks and transmitted over the chat channel.
This feature is still under active development and requires further changes and testing.
