I have a PDF that is Secured in Adobe Acrobat (File-->Properties-->Change-->Permissions section).

When I load that PDF in PDFium, it will load - though it should give me an InvalidPasswordException.

using (var doc = PdfDocument.Load("secured.pdf"))
catch (InvalidPasswordException)
throw new Exception("This PDF has a password and you don't know what it is!");

My code never hits the catch. It just loads the PDF without issue. To make matters worse, if I save the PDF:
doc.Save(@"secured-newpwd.pdf", SaveFlags.NoIncremental | SaveFlags.RemoveSecurity);

It actually saves a new PDF without the password even though I am never supplying the password.
