int hmac_md5	(	const u8 *	key,
		size_t	key_len,
		const u8 *	data,
		size_t	data_len,
		u8 *	mac
	)

HMAC-MD5 over data buffer (RFC 2104).

Parameters:

	key	Key for HMAC operations
	key_len	Length of the key in bytes
	data	Pointers to the data area
	data_len	Length of the data area
	mac	Buffer for the hash (16 bytes)

Returns:

0 on success, -1 on failure
