The chat public key is now also updated in the users table during key publishing for profile discovery. Additionally, sender handles in chat receive are now fully qualified with domain when necessary to ensure consistency in conversation and message storage.
Reorganizes useEffect hooks in chat/page.tsx to follow a helper-functions-first structure, improving readability and maintainability. Adds error handling and user feedback for compose intent, preventing UI flash while processing. In send/route.ts, ensures remote user handles are fully qualified and adds debug logging. Temporarily disables key caching in keys/route.ts to address development key mismatches.
Removed 'healing' logic and authoritative update propagation from handle registry and gossip code, simplifying handle upserts to only update on strictly newer timestamps. Enhanced sodium-chat key handling with robust base64 decoding and key repair logic. Added scripts for key inspection and crypto testing. Deleted unused healing module.
Added healing utilities to update the handle registry when a user profile is found at a new node domain. Enhanced upsertHandleEntries to accept a sourceDomain parameter, allowing authoritative updates from the owning node. Updated gossip logic to pass sender/target domains for proper trust handling during handle propagation. Integrated healing logic into chat key lookup to keep the registry accurate.
The GET /api/chat/keys endpoint now checks a remote identity cache and, if necessary, fetches keys from remote nodes or Swarm user profiles when a local key is not found. Results from remote lookups are cached for 24 hours to improve performance and reliability.
Replaces legacy chat encryption modules with new sodium-based implementation. Adds and updates API routes for chat key management and debugging, introduces new hooks and scripts for sodium chat, and updates related database schema and configuration. Removes old crypto modules and updates dependencies accordingly.
Introduces a new chat page with end-to-end encryption, conversation list, and message thread UI. Adds new API endpoints for unread message count and debugging chat keys/messages. Improves chat key validation and reciprocal conversation/message creation for local recipients. Removes the old ChatWidget component. Updates login and chat API logic for better Turnstile and key handling.
- Add chat keys API endpoint for storing and retrieving encrypted RSA public/private key pairs
- Create client-side crypto utilities for E2E encryption/decryption with hybrid encryption support
- Implement useChatEncryption hook for managing encryption state and key generation in chat UI
- Add chatPublicKey and chatPrivateKeyEncrypted fields to user schema for key storage
- Update chat messages API to return encrypted content with sender's public key for decryption
- Modify send message endpoint to accept pre-encrypted content from client while maintaining legacy server-side encryption
- Update chat page UI to integrate client-side encryption workflow
- Ensure private keys are encrypted client-side with user password before transmission to server
- Server cannot decrypt message content in E2E mode, providing true end-to-end encryption
