Google made faster Siphash variants, and also HighwayHash that's much faster. https://github.com/google/highwayhash

The critique. There's more rambling by (I think) the same author here: https://github.com/google/highwayhash/issues/28 His arguments are a little inconsistent and ambiguous, which suggests either a misunderstanding, perhaps a touch of…

I didn't know much about this argument so I looked it up and funny enough it's you arguing here too: https://github.com/google/highwayhash/issues/28 Still trying to wrap my head around exactly what is being argued... but it's starting to…

There was a recent effort by Google to speed up SipHash, it's called HighwayHash: https://github.com/google/highwayhash - it includes a compatible, optimized SipHash implementation (1.5x speedup), a variation on that that is not compatible…
