Adds robust session serialization/deserialization for ratchet state, session cleanup for corrupted data, and improved error handling in chat encryption hooks. Enhances chat delivery to support both local and remote recipients, ensures conversation creation, and adds timeouts to key fetches. Also introduces utilities for deleting and clearing encrypted session data from storage.
Refactors the chat key fetch API to support fallback lookups using user handle and did:web aliasing, improving reliability when primary lookups fail. Updates useChatEncryption to detect and repair 'Zombie State' where local keys exist but are missing on the server, ensuring keys are republished as needed. Modifies sendMessage to pass recipient handle and bind sessions to the correct DID, supporting aliasing scenarios.
Introduces an API route to proxy remote key bundle fetches, improving CORS handling for secure chat. Updates chat UI to handle error states and retries, enhances key/identity synchronization, and refactors message sending to support remote node domains. Also adds CORS preflight support to the .well-known chat route and improves in-memory key store management.
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
