Hi everyone,
As part of my crypto needs, I worked on implementing Keccak and finalised Chacha20 on RP2040.
But one thing led to another and I thought it might be worth pushing things a bit further and coding SHA3.

So I finalised the thing a few days ago and tested it with just about every vector I could think of.
It works properly and doesn't take up too much resources.
