Is it possible to verify if we can copy the content of a PDF document with iTextSharp?

I have a method that copy the content of the PDF and add a new page at the end with project's information but it throw a "System.ArgumentException: PdfReader not opened with owner password". I get this error when I do writer.GetImportedPage(reader, i);

Thanks for the help!

"System.ArgumentException: PdfReader not opened with owner password" - are you opening the pdf with the owners password? If not that would be your first step, if you are then that exception is misleading. - Jeremy Thompson
I don't have the password, I want to verify if a password is needed because a user can upload any PDF and I need to verify if I can copy this PDF. - VinnyG

You should be able to just check the property PdfReader.IsOpenedWithFullPermissions.

PdfReader r = new PdfReader("YourFile.pdf");
if (r.IsOpenedWithFullPermissions)
{
    //Do something
}
