💬 JavaFX Encrypted Chat with Hamming(7,4) Error Correction This is a basic client-server chat application built using JavaFX. It combines RSA encryption for secure messaging and Hamming(7,4) Error Correction Code (ECC) to detect and fix single-bit errors during transmission.
The goal of this project is to help you understand how encryption and error correction can work together in a real-time messaging system.
✨ Key Features ✅ Client-Server Chat – Connect to a server and chat with other users.
👥 Group & Private Messages – Send messages to everyone, or privately using @username.
🔐 RSA Encryption – Messages are encrypted on the client side using the server's public key and decrypted by the server using its private key.
🧠 Hamming(7,4) ECC – Adds error correction to the encrypted message, allowing the system to fix single-bit errors automatically.
🧪 Simulated Errors – A random 1-bit error is added on purpose to show how ECC fixes it.
🖼️ JavaFX User Interface – A simple and clean UI for sending and viewing messages.
📜 Message Details – Expand any message to view:
-Original text -Encrypted data -Hamming-encoded version -Simulated error -Error correction steps -Final decrypted message
🛠️ Maven Build System – Uses Maven to handle building and running the project easily.

🚀 Getting Started :
- Clone the Project bash Copy Edit
git clone https://github.com/your-username/JavaFX-Encrypted-Chat-Hamming.git
cd JavaFX-Encrypted-Chat-Hamming
- Build the Project bash Copy Edit :
- mvn clean compile
- Start the Server bash Copy Edit :
-mvn clean compile exec:java(Leave this terminal open. The server is now running and ready to accept clients.)
- Start a Client In a new terminal window, run: bash Copy Edit
-mvn clean javafx:run(A JavaFX window will open. Enter your username to join the chat.)
- Add More Clients (Optional)
To test with more users, repeat step 4 in new terminal windows.
