@brief HMAC-SHA1 over data vector (RFC 2104)

@key: Key for HMAC operations @key_len: Length of the key in bytes @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 (20 bytes) Returns: 0 on success, -1 on failure
