JSChat

JSChat is a fully encrypted terminal-based chat application built in Java. It provides secure communication between clients using AES and RSA encryption. The project consists of a server and a client, both of which must be running for communication to occur.

Features

• End-to-End Encryption: Uses AES for message encryption and RSA for key exchange.
• Terminal-Based: Simple command-line interface for ease of use.
• Multi-Client Support: The server can handle multiple clients at once.
• Automatic Key Exchange: Clients and the server securely exchange encryption keys at connection.

Requirements

• Java 11 or later

Installation

1. Clone or extract the project.
2. Navigate to the project directory.
3. Start the server.
4. Start as many clients as necessary.

Usage

Starting the Server

Run the server using:

./gradlew runServer -q --console plain

Starting a Client

Run the client using:

./gradlew runClient -q --console plain
