A short code to crack Experimental ElGamal cryptosystem and Rabin’s method.

System which encodes a message within an image or an audio file using a combination of cryptography and steganography, and decrypts it when the same multimedia file is provided. 🔐

This is a steganography application built using Flutter, allowing you to encode and decode messages within images. The app supports both mobile and desktop platforms.

The project aims at building its own cryptocurrency from scratch using blockchain technology. The project uses Python language along with Flask Frameworks to deploy it on a localhost server. This project therefore not only gets us to know about block chain, encryptions and keys but also brings us closer to the world of cryptocurrency.
