I have a question from one of our customers, can you please check below and let us know if this can be done and provide us with an example?

Customer request is to add an expiration date to the PDF so that even if downloaded, it would not be able to be opened after the date of expiry.

Thanks

Please use below complete code snippet and let us know in case you still notice any issues:

Document doc = new Document();
doc.getPages().add();

java.time.LocalDate date1 = java.time.LocalDate.now().minusDays(10);
int year = date1.getYear();
int mon = date1.getMonthValue();
int dated = date1.getDayOfMonth();

JavascriptAction javaScript = new JavascriptAction(
        "// Get the current date and time\n" +
                "var rightNow = new Date();\n" +
                "// Set End Date to 2021/04/01 for instance\n" +
                "var endDate = new Date(2021, 03, 01);\n" +
                "if(rightNow > endDate)\n" +
                "{\n" +
                "app.alert(\"This Document has Expired.\");\n" +
                "this.closeDoc();\n" +
                "}");

doc.setOpenAction(javaScript);
doc.save(dataDir + "PDFExpiry.pdf");

You do not have other options throw Aspose API that cannot be changed like above?

@aabuhijleh

It is not a bug in the API. In fact, it is a limitation of the functionality itself that you can achieve at the moment using Aspose.PDF.

Also you do not reply to my question do you have other options/ways throw Aspose API to set expiration date for PDF?

Sadly, there is no other way at the moment in order to achieve this requirement except the one that we already had shared with you.
