Differential Cryptanalysis

Final project for ECE 406: Applied Cryptography.

This project implements differential cryptanalysis to attack a simple cipher, as outlined in Linear Differential Cryptanalysis. The program utilizes multithreading to enhance performance, making the analysis faster and more efficient.

Usage

To run the project, use the following command:

cargo r

This will output

Cipher's round keys:
