Sveiki,

Reikia idiegti swedbank'o banklink sistema.
Ir susiduriau su tokia problema.
Gaunu atsakyma ir banko, bet niekaip negaliu patikrinti autentiskumo su 
banko sertifikatu.
Visada gaunu pranesima blogas parasas.

Gal kas galit padeti?

Paraso tikrinimo kodas:


$v = new Verify();

	if ($v->checkPaymentStatus() == true)
	{
		$currency = new Currency(intval($_REQUEST['VK_CURR']));
		$SwedbankBanklink = new SwedbankBanklink();
		$SwedbankBanklink->validateOrder($_REQUEST['VK_REF'], _PS_OS_PAYMENT_, 
$_REQUEST['VK_AMOUNT'], $SwedbankBanklink->displayName, NULL, NULL, 
$currency->id, true);
		
		if($_REQUEST['VK_AUTO'] == 'N'){
