Key recovery attack on SPN ciphers such as AES is NP hard in complexity. Previous studies have estimated the quantum resources required for implementing Grover’s key search for AES, but these are ...

A comprehensive educational cipher toolbox for encryption and decryption, featuring both classical and modern cryptographic algorithms — now with a built-in MCP (Model Context Protocol) server for AI ...

In the digital age, information is currency, and cryptography is the vault. Derived from the Greek words kryptos (hidden) and graphein (to write), cryptography has evolved from ancient military ...

This repository contains my complete solutions to the legendary Karan's Mega Project List — a curated collection of programming challenges designed to improve coding skills across multiple domains.

With the rapid development of digital communications, sensitive digital storage security, especially that of images, remains a significant challenge. Most of the existing hash algorithms cannot meet ...

As the title implies, these algorithms are just for fun (an excuse to hone your Python skills, if you need one). Please don't use them to encrypt any sensitive data. You've been warned. The first and ...
