Abstract

Stegosaurus is an open-source Cybersecurity & Ethical Hacking project. Encrypt and decrypt text and files with AES and RSA encryption and image steganography. A small app that can encrypt and decrypt text and files with AES and RSA encryption, as well as hide plain or encrypted data inside images. It is built using Python. The complete source code is publicly available on GitHub under the MIT License, making it a useful reference for students building a Cybersecurity & Ethical Hacking mini project or final-year project.

1. Introduction
