A secure messaging system developed with layered cryptography, combining RSA for secure key exchange, AES for fast symmetric encryption, and Arnold’s Cat Map for additional data scrambling, ensuring private, tamper-proof, and end-to-end secure real-time communication.

This is a simple program to practice secure communication between two parties. It uses RSA to encrypt and share symmetrical encryption key. This key is used to encrypt a message with AES, authenticate with HMAC, and authenticate with RSA signature over SHA-256 hash.
