128-bit encryption, no owner password

[IT_Hank]

We have an application that is creating a 128-bit encrypted PDF without user or owner passwords.  When performing a PdfCopy.GetImportPage method call, the GetImportPage method fails in version 4.1.1.0.  This worked in version 3.1.6.0.

The error might stem from the following:

//this is the error being thrown because false is being returend from "IsOpenedWillFullPermissions".

        internal PdfImportedPage GetImportedPage(int pageNumber) {
            if (!reader.IsOpenedWithFullPermissions)
                throw new ArgumentException("PdfReader not opened with owner password");

//this method returns false if encrypted and no password is supplied.

        public bool IsOpenedWithFullPermissions {
            get {
                return !encrypted || ownerPasswordUsed;
            }
        }

//this is the calling code
Snippet one…
     if (reportGuid != Guid.Empty)
     {
        SQLFileInfo inputInfo = new SQLFileInfo(reportGuid);
        using (SQLFileStream inputStream = inputInfo.Open(System.IO.FileMode.Open))
        {
            reader = new PdfReader(inputStream, null);
            if (copy == null)
            {
                doc = new Document(reader.GetPageSizeWithRotation(1));
                copy = new PdfCopy(doc, outputStream);
                doc.Open();
             }
            //copy the pages
             CopyPages(copy, reader);
          }
   }

Snippet two…
        private void CopyPages(PdfCopy copy, PdfReader reader)
        {
            for (int i = 1; i <= reader.NumberOfPages; i++)
            {
                //This is where the error happens
                copy.AddPage(copy.GetImportedPage(reader, i));
            }
        }

That's a legal imposition from Adobe. You must have the owner password.

Hello Paulo,

I have been looking on the Adobe site for the license that indicates that a owner password is required on a PDF document ("legal imposition).  I was wondering if you could point me to the correct license agreement that includes this text.  I need to pass this on to our business leaders.

Thank you,

Kevin

Hi Paulo, sorry to beat this to death, but I still couldn't find the referenced text in the latest PDF reference.  

From your message, it seems to be indicating that developers of software like PDF readers should respect the passwords and encryptions of the PDF documents that they are reading.  I don't see how this applys to iText and why iText should be required to automatically set the permissions password on generated PDF documents seeing these documents are being created and not consumed.  And if it is the wish of the PDF authour not to set a permissions password, then consumers of that PDF will need to respect that as well.

Thank you.  

Kevin

The text applies to PDFs that are read. If you are producing docs you may or may not apply restrictions. You should probably contact Adobe's legal department about this if you still have doubts.

Thanks Paulo,  but that is what I mean.  iText applies the permissions password automatically if the permissions password is not provided by the PDF creator, as is done in Acrobat.  I find nothing that states that this needs to be the case.  Only the reader of the document needs to respect the permissions and passwords (no cracking).  

You are correct, I will need to contact Adobe Legal, maybe they will respond in 9 months or so. :-)  

I assume you need a password (owner or user) for a document to be encrypted?  The ideal is to have a password protected, non-encrypted document.  The reason is that we have run across a piece of software that when a user trys to forward an email with one of our PDFs (encrypted/permission password protected), the email security tries to encrypt the email, but this fails becuase of the encrypted PDF.  Just trying to get around that.

Thanks Paulo for all that you do.

Hi,

I want to rotate all pages inside a PDF file with 90,180 or 270 degrees.
Is it possible with iTextSharp?

Thanks, Ben

Hi Paulo,

Thanks, i forgot stp.Close().

Unfortunatly i'm not ready yet. I need to convert the rotated document to the PDF/A standard but after doing this the original rotation is restored.
Is this a know problem?

Thanks, Ben

There's nothing in the PDF/A standard about restricting the page rotation. Where does your PDF/A conversion program gets the original rotation from or does it just erase the key (setting it to 0)?

I use this code for conversion to PDF/A:

PdfReader pdfReader = new PdfReader(Scans[0].ToString());
iTextSharp.text.Rectangle docSize = pdfReader.GetPageSize(1);
Document doc = new Document(docSize);
PdfWriter pdfWriter = PdfWriter.GetInstance(doc, new FileStream(tempFile, FileMode.Create));
if (_pdfAType == 0)
{
    pdfWriter.PDFXConformance = PdfWriter.PDFA1A;
}

if (_pdfAType == 1)
{
    pdfWriter.PDFXConformance = PdfWriter.PDFA1B;
}

doc.Open();


PdfContentByte pdfContentByte = pdfWriter.DirectContent;
PdfDictionary pdfDic = new PdfDictionary(PdfName.OUTPUTINTENT);
pdfDic.Put(PdfName.OUTPUTCONDITIONIDENTIFIER, new PdfString("sRGB IEC61966-2.1"));
pdfDic.Put(PdfName.INFO, new PdfString("sRGB IEC61966-2.1"));
pdfDic.Put(PdfName.S, PdfName.GTS_PDFA1);
ICC_Profile icc = ICC_Profile.GetInstance(Path.GetDirectoryName(Application.ExecutablePath) + \\srgb.profile);
PdfICCBased ib = new PdfICCBased(icc);
ib.Remove(PdfName.ALTERNATE);
pdfDic.Put(PdfName.DESTOUTPUTPROFILE, pdfWriter.AddToBody(ib).IndirectReference);
pdfWriter.ExtraCatalog.Put(PdfName.OUTPUTINTENTS, new PdfArray(pdfDic));
if (_pdfAType == 0)
{
    PdfDictionary markInfo = new PdfDictionary(PdfName.MARKINFO);
    markInfo.Put(PdfName.MARKED, new PdfBoolean(true));
    pdfWriter.ExtraCatalog.Put(PdfName.MARKINFO, markInfo);
}
PdfImportedPage importedPage = pdfWriter.GetImportedPage(pdfReader, 1);
pdfContentByte.AddTemplate(importedPage, 0, 0);
doc.AddTitle(Path.GetFileName(Scans[0].ToString()));
doc.AddCreator("PDF-A Conv");
pdfWriter.CreateXmpMetadata();
doc.Close();
