Implementations of BLAKE2sp and BLAKE2bp #31

Open pedrocr opened 7 years ago

pedrocr commented 7 years ago

Apparently BLAKE2 includes parallel versions of the two hash functions to take advantage of multi-core:

It would be nice to have these to be able to take advantage of more cores when hashing large files.

These would also be useful as SIMD implementations, enabling dramatic speedups on common hardware without any extra threads at all.

I started working on the issue.

I am currently making a script to convert test data from the BLAKE2 repo to blobs in the hashes repo.

FYI, I just rebased #228 which completely replaces the current implementation with blake2-simd

pczarn commented 1 year ago

@tarcieri Okay, I can see that blake2-simd includes both parallel variants.
