Hi All, Just reposting my previous question in a clearer way in the hope that some friendly person has a solution...
I'm trying to fill in XFA values and encrypt a PDF containing an XFA form. From reading Paulo's replies when encryption questions pop up, I know the encryption needs to be done as soon as the stamper is created. so the code I'm using looks like: ... ByteArrayOutputStream baos = new ByteArrayOutputStream(); PdfStamper stamper = new PdfStamper(passedPdfReader, baos); stamper.setEncryption(PdfWriter.ENCRYPTION_AES_128, "", "", PdfWriter.ALLOW_PRINTING); XfaForm xfaForm = stamper.getAcroFields().getXfa(); xfaForm.fillXfaForm(passedInputSource); stamper.setFullCompression(); stamper.close(); return baos.toByteArray(); ... However, this doesn't do what I'd expect. It ignores all the filled XFA values leaving blank fields in the final PDF. I've tried all 4 of the various similar setEncryption() methods on PdfStamper, but they all do the same thing - they cause the filled XFA data values to not appear in the final PDF. If setEncryption() is removed, the final PDF is filled in ok, but unsecured. If setEncryption() (in any of the 4 similar variants) is enabled, the final PDF is secured, but with no XFA data filled in. I've also tried using stamper.getWriter().setEncryption(byte[], byte[], int, int), using null byte arrays rather than empty strings for the passwords. But that also had the same problem. The passwords are left null/empty so that iText uses its random password generation - because we don't need to unsecure the final PDF, and we'd prefer not to have any record of the passwords. The variant of setEncryption() which takes a Certificate array hasn't been tried, since I don't have any public certificates to use. Has anyone got any suggestions to encrypt an XFA PDF without losing all the added form data?
