PBKDF2_SHA256()

void PBKDF2_SHA256	(	const uint8_t *	passwd,
		size_t	passwdlen,
		const uint8_t *	salt,
		size_t	saltlen,
		uint64_t	c,
		uint8_t *	buf,
		size_t	dkLen
	)

PBKDF2_SHA256(passwd, passwdlen, salt, saltlen, c, buf, dkLen): Compute PBKDF2(passwd, salt, c, dkLen) using HMAC-SHA256 as the PRF, and write the output to buf.

The value dkLen must be at most 32 * (2^32 - 1).
