Programmatically enable Adobe PDF usage rights

Question

Is there any way to programmatically enable Adobe PDF usage rights from .net code ? I'm using ITextSharp library to fill an XFA Form with XML Data (generated from app), but the output PDF does not have usage rights enabled, thus the users cannot interact with it (that wouldn't normally be a problem, BUT the original PDF is gov supplied, and the user must click some validation buttons, and that process is user/company specific)

This could be manually accomplished from Adobe Reader but you have to have an adobe acrobat professional licence..

Google is saying that "Only Adobe products can do that" .. (http://old.nabble.com/Enable-Adobe-Reader-usage-rights-td14276927.html)

string pathPDF = @"C:\original.pdf";
string pathCreated = @"C:\created.pdf";
string pathXml = @"C:\data.xml";

using (PdfStamper stamper = new PdfStamper(new PdfReader(pathPDF), System.IO.File.OpenWrite(pathCreated)))
{
    stamper.FormFlattening = false;
    stamper.AcroFields.Xfa.FillXfaForm(pathXml);

    stamper.Close();
}

The only way to do it programitically is to use Adobe Reader Extension Server. You can review Adobe whitepaper here: http://www.adobe.com/sea/products/server/readerextensions/pdfs/readerextensionsserver_ds.pdf

In the case above you would use iTextSharp to create Pdf document and then use Adobe Reader Extension Server to allow Pdf document to have extended functionality in Adobe Reader.

However, there is a small window that allows you to work with iTextSharp and fill-in already Reader-enabled PDF documents. If you have such Pdf document (Reader Enabled), then you can use iText/iTextSharp to fill in XFA data. You can check example here: http://itextpdf.com/examples/iia.php?id=166

Good luck!

pdfReader.removeUsageRights() did the trick for me. Thank you very much @Dmitry, your help is greatly appreciated :) — danmaier2010, Mar 11 '11 at 07:39

Currently only 2 products can enable usage rights:

Adobe Acrobat - for less that 500 users
Adobe LiveCycle Reader Extensions - more than 500 users

There have been some findings regarding this feature here.

Datalogics PDF Java Toolkit (http://www.datalogics.com/products/pdf/pdfjavatoolkit/) can be used to reader enable PDFs (add usage rights) programmatically. Disclaimer, I work for Datalogics. – Brandon Haugen May 03 '17 at 19:32

This worked for me:

            string TempFilename = Path.GetTempFileName();

            PdfReader pdfReader = new PdfReader(FileName);
            //PdfStamper stamper = new PdfStamper(pdfReader, new FileStream(TempFilename, FileMode.Create));
            PdfStamper stamper = new PdfStamper(pdfReader, new FileStream(TempFilename, FileMode.Create), '\0', true);

            AcroFields fields = stamper.AcroFields;
            AcroFields pdfFormFields = pdfReader.AcroFields;

            foreach (KeyValuePair<string, AcroFields.Item> kvp in fields.Fields)
            {
                string FieldValue = GetXMLNode(XMLFile, kvp.Key);
                if (FieldValue != "")
                {
                    fields.SetField(kvp.Key, FieldValue);
                }
            }

            stamper.FormFlattening = false;
            stamper.Close();
            pdfReader.Close()

yeah adding those params '\0', true did the trick to the new PdfStamper. I got the answer from http://itextpdf.com/examples/iia.php?id=166 — hamish, Aug 26 '14 at 23:00

No. Adobe uses Strong Crypto to ensure it... PPK I believe.

Google is saying that "Only Adobe products can do that"

That's because only Adobe products can do that. You can pay for some Acrobat server product or other... $$$... but that's it.

you can complete it using PdfStamper when using PdfStamper use thi code

PdfStamper pdfStamper = new PdfStamper(pdfReader, new FileStream(
                                                                      newPath, FileMode.CreateNew, FileAccess.Write), '\0', true);

if the form is Reader Extension enabled it will work
