    private static $db = [
        'NormalText' => 'Varchar'
        'SecureText' => EncryptedVarchar::class

}

// Via DataObject::get()
$obj = SecureDataObject::get()->first()->SecureText; // Returns the decrypted string from the field

// Getting the DB field
$obj = SecureDataObject::get()->first();
$field = $obj->dbObject('SecureText'); // Returns an EncryptedVarchar object
$uppercase = $field->UpperCase(); // Method on DBString, returns a string

use Madmatt\EncryptAtRest\AtRestCryptoService;

$text = 'This is an unencrypted string!';

/** @var AtRestCryptoService $service */
$service = Injector::inst()->get(AtRestCryptoService::class);
$encryptedText = $service->encrypt($text); // Returns encrypted string starting with `def`
$unencryptedText = $service->decrypt($encryptedText); // Returns 'This is an unencrypted string!'

$file = File::get()->byID(1); // Presume this is a file that contains the text string above

// This will encrypt the file contents, delete the original file from the filesystem and create a new file at the same path with .enc appended to the filename
$encryptedFile = $service->encryptFile($file);

// This will decrypt the file contents, delete the encrypted file from the filesystem and create a new file at the same path with .enc stripped from the filename
$decryptedFile = $service->decryptFile($encryptedFile);
