PyQt5 Chat Application

A secure chat application using PyQt5 with an intuitive graphical user interface, leveraging modern cryptographic practices to securely connect a client and a server.

Overview

This application provides a simple and secure way to chat between systems. It employs X25519 key exchange for secure key negotiation, and AES-GCM for data encryption, ensuring confidentiality and integrity in message exchange.

Features

• Dual Mode Operation: Choose between Client or Server modes for communication.
• Secure Key Exchange: Utilizes X25519 for efficient and secure key exchange.
• AES-GCM Encryption: Ensures high security for messages with AES-GCM encryption.
• Resilient Connections: Automatically attempts reconnection upon network disruption.
• User-Friendly GUI: Built with PyQt5, offering a clean and responsive interface.
• Message Alignment: Chat messages are visually distinct, aligning client messages left and server messages right.
