Encrypted TCP Chat Application

A simple TCP-based chat application in Python with encrypted message transmission, built using sockets and the cryptography library. This app allows two users to chat over a TCP connection, with messages encrypted to ensure secure communication.

Features

• Encrypted Message Transmission: Messages are encrypted using symmetric encryption for secure transmission.
• TCP Connection: Relies on TCP sockets for reliable data transfer.
• User Interface (Optional): Basic command-line interface; can be extended to a GUI.

Prerequisites

• Python 3.6+
• Install cryptography library:

  pip install cryptography

Installation

1. Clone the repository:

   git clone https://github.com/yourusername/tcp-chat-app.git
   cd tcp-chat-app

2. Ensure server.py and client.py scripts are in the same directory.

Usage

1. Run the Server:

   • In a terminal, navigate to the directory and start the server:

     python server.py

   • The server will listen for a connection on localhost:10000.

2. Run the Client:

   • In a separate terminal, run the client script:

     python client.py

   • Connects to the server, enabling encrypted chat communication.

3. Chat!

   • Type your message in the client terminal. Messages are encrypted and sent to the server.

How It Works

• TCP Socket: socket is used to establish a connection between server and client.
• Encryption: Messages are encrypted using a symmetric key (AES encryption) for secure transmission.
