A small library for AES encryption in both ECB and CBC modes

A very basic cipher block chaining (CBC) implementation in C. It supports extended ASCII and block sizes up to 32 bits (signed).

Ce projet est une implémentation éducative d'un ransomware en C, utilisant l'algorithme de chiffrement AES-256 en mode CBC. Ce projet est uniquement destiné à des fins éducatives et ne doit pas être utilisé à des fins malveillantes.
