Secure Chat Application

This is a secure chat application built using Java, implementing multithreading to handle multiple clients simultaneously and cryptographic utilities to ensure secure communication between users. The application supports real-time messaging with encryption to safeguard data integrity and confidentiality.

Features End-to-End Encryption: Uses cryptographic algorithms (e.g., AES/RSA) to encrypt messages exchanged between clients. Multithreading: Ensures simultaneous handling of multiple clients in a scalable way, providing real-time communication. Client-Server Architecture: The chat system follows a client-server model, where the server manages multiple client connections and the secure exchange of messages. Message Integrity: Verifies that messages are not tampered with during transit by using cryptographic checks (e.g., message digests). User Authentication: Basic user authentication to ensure secure access. Thread-Safe Communication: Proper synchronization mechanisms for secure and safe message handling across multiple threads. How It Works Multithreading: The server handles multiple clients concurrently, assigning a dedicated thread to each connected client.
