The SHA-256 Project: learn how hash functions work by implementing one yourself
I was hoping this would explain a bit more about <i>why</i> the algorithm does the things it does. Do we have proofs for why certain types of mixing are more secure than others?<p>Also, it&#x27;s funny how even world-class cryptographers can think it&#x27;s perfectly fine to <i>directly output internal state</i> as the digest. Some things are only obvious in retrospect.
