Crypto Library

Introduction

This project implements core cryptographic primitives from scratch in C++ for educational purposes, with a focus on understanding the underlying mathematical and algorithmic foundations of cryptography.

Current implementations

Hash: MD5, SHA1, SHA256, SHA384, SHA256.
AES: ECB, CBC.
