Encryptable

The encryptable trait can automatically encrypt and decrypt attributes on your models

• Usage
  • Unsafe Decryption

Usage

class BankAccount extends Model
{
    protected $casts = [
        'number'    => 'encrypt',
        'sort_code' => 'encrypt',
    ];
}

This model will now automatically encrypt and decrypt the number and sort_code attributes when saving/retrieving from the database.

Unsafe Decryption

By default if a DecryptException is thrown when attempting to decrypt the attribute, the encryptable trait will catch the exception and safely return the unaltered contents of the attribute, this is to prevent any unexpected exceptions in your application. If you wish to change this behaviour and have the DecryptException thrown then you may set the protected $safeDecrypt = false property on your model.

class BankAccount extends Model
{
    protected $casts = [
        'number'    => 'encrypt',
        'sort_code' => 'encrypt',
    ];

    protected $safeDecrypt = false;
}

Now when the number or sort_code attributes fail to decrypt (e.g because of an invalid hmac) then the DecryptException will be thrown and you can handle it within your application however you need to.
