PyLock is a password manager that allows users to securely store and retrieve their passwords. It uses encryption to ensure that the stored passwords are safe and protected.

Data cryptography in frontend with crypto.js

Repository containing all the materials and assignments from the course I used/solved.

The Trading Alert System is an automated solution designed to streamline and enhance traders’ decision-making processes by providing real-time notifications. This system delivers actionable trading alerts—buy, sell, and suggestion signals—directly to traders through popular communication platforms.

Feistel cypher based on TwoFish and SkipJack. Not my design, although I did write the code.

This project generate unique public key and the private key associated with it, it can sign and send ethers to any public address

Python implementation of RSA cryptosystem showing the encryption and decryption algorithms as well as the possible attacks.

AES is a symmetric encryption algorithm standardized by the National Institute of Standards and Technology (NIST). It operates on fixed block sizes of 128 bits and employs a 128-bit key to encrypt and decrypt data securely. AES is widely used for securing sensitive data due to its strong encryption, efficiency, and resistance to most known attacks
