Scrypt key derivation function for Yii2

To use it just require this extension in your composer.json file:

"alexandernst/yii2-scrypt": "0.0.4",

And then add it to your components configuration in Yii2:

'components' => [
	'Scrypt' => [
		'class' => 'alexandernst\Scrypt\Scrypt'
	],
]

To derivate a key, use the following method:

/**
* Scrypt algorithm
*
* @param  string $password
* @param  string $salt
* @param  int $n CPU/Memory cost parameter, must be larger than 1, a power of 2 and less than 2^(128 * r / 8)
* @param  int $r Block size
* @param  int $p Parallelization parameter, a positive integer less than or equal to ((2^32-1) * hLen) / MFLen where hLen is 32 and MFlen is 128 * r
* @param  int $length Length of the output key
* @throws Exception
* @return string
*/
echo bin2hex(\Yii::$app->Scrypt->calc("plain password", "salt", 8, 8, 16, 32));

This class passes all the tests specified in the documentation.
