Hi Philip,

Thanks for your patience.

During our testing with latest release of Aspose.Pdf for .NET, both following techniques/codes work fine.

PdfFileSecurity fileSecurity = new PdfFileSecurity(input(“Created%2bwith%2bFoxit%2b-%2bPassword%2bis%2bxxx.pdf”), output(“output.pdf”));<o:p></o:p>

//decrypt PDF document


and also

Document doc = new Document(input("Created%2bwith%2bFoxit%2b-%2bPassword%2bis%2bxxx.pdf"), "xxx");
