A c++ program that implements the Sha-256 hashing algorithm.
The algorithm is outlined very clearly here: https://nvlpubs.nist.gov/nistpubs/FIPS/NIST.FIPS.180-4.pdf.
https://www.youtube.com/watch?v=orIgy2MjqrA is a fantastic video that goes over every step of the algorithm.
My first real attempt at a project in cpp!
