HKDF-SHA256 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 - .

• 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 - .
