create_kdf_key()

int create_kdf_key	(	const unsigned char *	key,
		const unsigned int	key_length,
		unsigned char *	rkey,
		unsigned int	rkey_size,
		vector< string > *	kdf_options
	)

Creates the required size of key using supplied key and KDF options.

KDF: key derivation function (KDF) is a cryptographic algorithm that derives one or more secret keys from a secret value such as a main key, a password, or a passphrase using a pseudorandom function (which typically uses a cryptographic hash function or block cipher)

Parameters

	key	Input key
	key_length	Input key length
[out]	rkey	output key
	rkey_size	output key length
	kdf_options	KDF function options

Returns

0 on success and 1 on failure
