AES is a symmetric encryption algorithm standardized by the National Institute of Standards and Technology (NIST). It operates on fixed block sizes of 128 bits and employs a 128-bit key to encrypt and decrypt data securely. AES is widely used for securing sensitive data due to its strong encryption, efficiency, and resistance to most known attacks

This project implements the SHA-256 cryptographic hash function in Verilog. It includes a modular design with separate modules for various components, as well as testbenches written in Python using Cocotb for simulation and verification.
