Further hash benchmarking - SHA256 vs SHAKE256

Development
1

I’d be interested and seeing some benchmarks of SHAKE256 (i.e. SHA-3 with the same security as the current SHA256 we use) vs SHA256.

Anyone up for running https://github.com/calmh/gohashcompare/releases/tag/v0.2 ?

SHAKE256 is ~24% faster.

Will run it on my raspberry pi as well when I am at home.

Ok. So faster on fast computers, slower on ARM. Too bad.
