🔷🔷 About 🔷🔷

This Fundamental Cryptography in Theory and Python lesson is the 1st of 2 parts demonstrating, how SHA-256 as a hash function can be implemented in Python straight out of the official standardization document NIST FIPS PUB 180-4.

In this first part, the implementation of SHA-256 is set up by writing a driver using official NIST test vectors. Then, the implementation of the SHA-256 message pre-processing is demonstrated.

All code demonstrated serves educational purposes only.
