HKDF-SHA512 algorithm.

A new pseudo-random key of length r_len is derived from an input key key, a salt salt and additional information info. The new key is put into r.

Parameters

[out]	r	Output key.
	r_len	Length of r.
	key	Input key.
	key_len	Length of key.
	salt	Salt.
	salt_len	Length of salt salt.
	info	Additional information.
	info_len	Length of info.
