Changing cipher method

By default cipher is AES 256 CBC, you can change this by adding a 3rd parameters, for exemple :

$encrypted = Enkryptor::encrypt('test', 'password', 'des-ede3-cfb1');
var_dump($encrypted);

$decrypted = Enkryptor::decrypt($encrypted, 'password', 'des-ede3-cfb1');
var_dump($decrypted);

You can get available cipher methods by using

var_dump(Enkryptor::cipherList());
