# Secure Chat Application

This project is a real-time chat application built with Node.js, Express, and Socket.io, featuring end-to-end encryption (E2EE) for secure messaging. Users can join chat rooms, send messages, and use emojis, all while ensuring that their conversations remain private and secure.

## Features

- **Real-time Communication**: Instant messaging using WebSockets via Socket.io.

- **End-to-End Encryption**: Messages are encrypted on the sender's side and decrypted on the recipient's side, ensuring privacy and security.

- **Public Key Exchange**: Each user generates a public/private key pair, with public keys exchanged to enable encryption.

- **Multiple Chat Rooms**: Users can join existing chat rooms or create new ones.

- **Emoji Support**: Users can include emojis in their messages using an emoji picker.

- **User List and Room Information**: Display of current users in the chat room and the room name.
