of_pbkdf2()

void of_pbkdf2	(	OFHMAC *	HMAC,
		size_t	iterations,
		const unsigned char *	salt,
		size_t	saltLength,
		const char *	password,
		size_t	passwordLength,
		unsigned char *	key,
		size_t	keyLength
	)

Derive a key from a password and a salt.

Note

This will call reset (OFHMAC) on the OFHMAC first, making it possible to reuse the OFHMAC, but also meaning all previous results from the OFHMAC get invalidated if they have not been copied.

Parameters

HMAC	The HMAC to use to derive a key
iterations	The number of iterations to perform
salt	The salt to derive a key with
saltLength	The length of the salt
password	The password to derive a key from
passwordLength	The length of the password
key	The buffer to write the key to
keyLength	The desired length for the derived key (key needs to have enough storage)
