Function Documentation

int md4_vector	(	size_t	num_elem,
		const u8 *	addr[],
		const size_t *	len,
		u8 *	mac
	)

MD4 hash for data vector.

Parameters:

	num_elem	Number of elements in the data vector
	addr	Pointers to the data areas
	len	Lengths of the data blocks
	mac	Buffer for the hash

Returns:

0 on success, -1 on failure
