A lightweight client-server chat system built in C++ using the WinSock API. The project demonstrates networking fundamentals, multithreading, and secure user management through a modular design.

Server Component:

- Manages client connections, authentication, and active sessions.

- Uses unordered_map and mutex locks for thread-safe handling of user registries and active socket communication.

- Maintains detailed logs for user commands and public chat messages.

Client Component:

- Handles user registration, login flow, and state management through a structured ClientState enum.

- Uses socket-based communication with synchronization mechanisms to ensure safe concurrent operations.

Features:

- Basic authentication and credential storage.

- Real-time text message exchange between clients via the server.

- Logging system for both server commands and public messages.
