Laravel's Crypter class provides a simple interface for handling secure, two-way encryption. By default, the Crypter class provides strong AES-256 encryption and decryption out of the box via the Mcrypt PHP extension.
Note: Don't forget to install the Mcrypt PHP extension on your server.
$encrypted = Crypter::encrypt($value);
$decrypted = Crypter::decrypt($encrypted);
Note: It's incredibly important to point out that the decrypt method will only decrypt strings that were encrypted using your application key.
