Hi All,

I am trying to certify a PDF which has an empty signature field and a text
field, using the code below, allowing only signing to be done later in the
existing empty signature field but when I opened the certified document in
Acrobat 7, it does not allow me to sign any empty signature field.

Here is the code I am trying:

  System.out.println("Signing and Certifying...");
  PdfReader reader = new PdfReader(m_strInputPDFDocument);
  FileOutputStream fout = new FileOutputStream(a_strOutputPDFDocument);

  // creating the appearance
  PdfStamper stp = PdfStamper.createSignature(reader, fout, '\0', null,
false);
  PdfSignatureAppearance sap = stp.getSignatureAppearance();
  sap.setCrypto(key, chain, null, PdfSignatureAppearance.WINCER_SIGNED);
  sap.setReason("I'm the author");
  sap.setLocation("Lisbon");
  sap.setCertified(true);
  stp.setEncryption(true, "","testing", 256);//encrypt with no open PDF
permissions

When I am only encrypting the PDF, 256 parameter does work correctly works
and I can sign the PDF later on.
I am using iText 1.4.6 with JRE 1.5.

Am I doing some thing wrong here.

Best Regards,
Wahaj
