PySecNet

PySecNet is an open-source project that provides a simplified implementation of SSL/TLS (Secure Sockets Layer / Transport Layer Security) in Python.

This project focuses on key cryptographic components such as AES encryption, SHA-256 hashing, Diffie-Hellman key exchange, and RSA encryption for secure communication.

Key Features

Cryptographic Primitives: Essential cryptographic primitives ensuring data confidentiality, integrity, and authenticity.

Client-Server Architecture: A client-server architecture that allows secure communication between two parties.

SSL/TLS-like Functionality: Establishes secure connections and protects data during transmission.

Handshake Protocol: A handshake protocol inspired by SSL/TLS to negotiate cryptographic parameters and exchange keys securely.

PKI System: A basic Public Key Infrastructure (PKI) system for certificate generation, signing, and verification.

Interactive Choice: Choose to run the client or server, interactively or via command-line arguments.

This project serves as a practical resource for understanding and implementing secure communication protocols in Python. Feel free to explore and contribute.
