Zero-correlation linear cryptanalysis is an important method to analyze the security of block ciphers. But there are few works on zero-correlation linear attacks combined with the related-key setting.

Project 2 in a cybersecurity learning portfolio. This project teaches encryption and decryption fundamentals using classical ciphers, starting with Caesar Cipher and expanding into analysis features.

This repository provides a C# implementation of a basic mixed alphabet cipher. This cipher is a simple substitution cipher where each letter of the plaintext is replaced by a different letter of the ...
