Detailed Description

Hash algorithms based on the SKINNY block cipher.

The SKINNY-AEAD family includes two hash algorithms:

• SKINNY-tk3-HASH with a 256-bit hash output, based around the SKINNY-128-384 tweakable block cipher. This is the primary hashing member of the family.
• SKINNY-tk2-HASH with a 256-bit hash output, based around the SKINNY-128-256 tweakable block cipher.

Function Documentation

int skinny_tk2_hash	(	unsigned char *	out,
		const unsigned char *	in,
		unsigned long long	inlen
	)

Hashes a block of input data with SKINNY-tk2-HASH to generate a hash value.

Parameters

out	Buffer to receive the hash output which must be at least SKINNY_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.
