pbkdf2_sha256()

void pbkdf2_sha256	(	const uint8_t *	password,
		size_t	password_len,
		const uint8_t *	salt,
		size_t	salt_len,
		int	iterations,
		uint8_t *	output
	)

Create a key from a password and hash using PBKDF2.

Parameters

[in]	password	password pointer
[in]	password_len	length of password
[in]	salt	salt pointer
[in]	salt_len	salt length, recommended 64bit
[in]	iterations	number of rounds. Must be >1. NIST’s detailed guide (Appendix A.2.2), recommended 10000
[out]	output	array of size PBKDF2_KEY_SIZE
