Secure File Storage in Cloud Computing using Hybrid Cryptography Algorithms. Colossus ensures security of the user’s data stored on cloud (AWS S3) by providing a tool that helps to encrypt files using AES and RSA. The user receives the key via email.

Advanced-Data Security using multiple cryptographic algorithms over multiple layers and secured key sharing.

A website that uses hybrid of four standard cryptographic ciphers to encrypt a text document. Technologies used: python flask framework with cryptography libraries.

nodejs rest api - symmetric and asymmetrical encryption

Crypto helper

AndroidHybridCrypto is simple customizable Android implementation of hybrid cryptography (AES+RSA+Hash) recommended by OWASP.

Hybrid quantum-classical encryption system using BB84 protocol, AES-256, HMAC, and optional post-quantum signatures. Includes full GUI and scientific metrics logging.

Python-based cryptographic tool designed to help users encrypt and decrypt data using various algorithms.

This is the project for the CSE451 Computer and Networks Security course in the Faculty of Engineering, Ain Shams University. In this project, we implement secure file transfer over FTP. More details in README.
