Hacl.Blake2b_256SourceVectorized BLAKE2b implementation, requiring 256-bit vector support
Buffers have the following size constraints:
key: <= 64 bytes for BLAKE2b, <= 32 bytes for BLAKE2sdigest: non-zero, <= 64 bytes for BLAKE2b, <= 32 bytes for BLAKE2shash ?key msg size hashes msg and returns a digest of length size. An optional key argument can be passed for keyed hashing.
