Password not setting when setPaper() is called

[T4-OmkarS]

if call setPaper() then generated PDF is not password protected, if setPaper() is commented out then generated PDF is password protected. Here is my code:

$dompdf = new Dompdf();
$dompdf->setPaper('A4');
$dompdf->getCanvas()->get_cpdf()->setEncryption('a1234', 'a1234', ['print', 'modify', 'copy', 'add']);
$dompdf->loadHtml($html);
$dompdf->render();
$dompdf->stream();

I am using dom pdf version 2.0.4 and my PHP version is 7.4

Due to a quirk in the way Dompdf manages the Cpdf canvas adapter if the page size differs from the page size specified in the Options when Dompdf is initialized, then Cpdf is re-initialized on render. You can work around the issue by either:

1. set the password after the document is rendered
2. initialize Dompdf with the desired page size (e.g., $dompdf = new Dompdf(["defaultPaperSize" => "A4"]))
