Detailed Description

BLAKE2s implementation for performance comparisons.

BLAKE2s is not one of the NIST lightweight submissions. We use it as a baseline to evaluate the performance of other hash algorithsm. For example, a performance result of "1.2 BLAKE's" means that the algorithm is 1.2 times faster than BLAKE2s on the same input data on the same hardware.

This BLAKE2s implementation is based on the one from the Arduino Cryptography Library.

Function Documentation

int internal_blake2s_hash	(	unsigned char *	out,
		const unsigned char *	in,
		size_t	inlen
	)

Hashes a block of input data with BLAKE2s to generate a hash value.

Parameters

out	Buffer to receive the hash output which must be at least BLAKE2S_HASH_SIZE bytes in length.
in	Points to the input data to be hashed.
inlen	Length of the input data in bytes.

Returns

Returns zero on success or -1 if there was an error in the parameters.
