Hash the salt?

[hayr-hotoca]

Thanks for your works on this!

I want to leave up the password and salt(could be username, email, phone, ...) for the user and save the key and the key of the salt like below is it a good practice?

const N = 65536, r = 8, p = 1;
const dkLen = 32;

function hash(password, salty) {
	const passwordBuffer = new buffer.SlowBuffer(password.normalize('NFKC'));
	const saltBuffer = new buffer.SlowBuffer(salty.normalize('NFKC'));
	const saltKey = scrypt.syncScrypt(saltBuffer, saltBuffer, N, r, p, dkLen);

	const key = scrypt.syncScrypt(passwordBuffer, saltKey, N, r, p, dkLen);
	const hexKey = Buffer.from(key).toString('hex');
	const hexSalt = Buffer.from(saltKey).toString('hex');

	return hexKey+":"+hexSalt;
}
