The good way to achieve it is to decorate this class and define the new version of the getCrypt() method as follows there:

PHP Code:

protected function getCrypt()
    {
        $currency = $this->transaction->getCurrency();

        $shippingAddress = $this->getProfile()->getShippingAddress();
        if (null === $shippingAddress) {
            $shippingAddress = $this->getProfile()->getBillingAddress();
        }

        $fields = array(
            'VendorTxCode'      => $this->getTransactionId(),
            'ReferrerID'        => '653E8C42-AD93-4654-BB91-C645678FA97B',
            'Amount'            => round($this->transaction->getValue(), 2),
            'Currency'          => strtoupper($currency->getCode()),
            'Description'       => 'Your Cart',

            'SuccessURL'        => $this->getReturnURL(null, true),
            'FailureURL'        => $this->getReturnURL(null, true, true),

            'CustomerName'      => $this->getProfile()->getBillingAddress()->getFirstname()
                . ' '
                . $this->getProfile()->getBillingAddress()->getLastname(),
            'BillingSurname'    => $this->getProfile()->getBillingAddress()->getLastname(),
            'BillingFirstnames' => $this->getProfile()->getBillingAddress()->getFirstname(),
            'BillingAddress1'   => $this->getProfile()->getBillingAddress()->getStreet(),
            'BillingCity'       => $this->getProfile()->getBillingAddress()->getCity(),
            'BillingPostCode'   => $this->getProfile()->getBillingAddress()->getZipcode(),
            'BillingCountry'    => strtoupper($this->getProfile()->getBillingAddress()->getCountry()->getCode()),

            'DeliverySurname'    => $shippingAddress->getLastname(),
            'DeliveryFirstnames' => $shippingAddress->getFirstname(),
            'DeliveryAddress1'   => $shippingAddress->getStreet(),
            'DeliveryCity'       => $shippingAddress->getCity(),
            'DeliveryPostCode'   => $shippingAddress->getZipcode(),
            'DeliveryCountry'    => strtoupper($shippingAddress->getCountry()->getCode()),

            'Basket'             => $this->getBasket(),
            'AllowGiftAid'       => 0,
            'ApplyAVSCV2'        => 0,
            'Apply3DSecure'      => 0,
        );

        if ('US' === $fields['BillingCountry']) {
            $fields['BillingState'] = $this->getProfile()->getBillingAddress()->getState()->getCode();
        }

        if ('US' === $fields['DeliveryCountry']) {
            $fields['DeliveryState'] = $shippingAddress->getState()->getCode();
        }

        $cryptedFields = array();
        foreach ($fields as $key => $value) {
            $cryptedFields[] = $key . '=' . $value;
        }

        return $this->encryptAndEncode(implode('&', $cryptedFields));
    } 


Please, let me know if it helps.
