Subject Update Signature Contents
Date Mon, 02 May 2016 21:16:06 GMT
Hello all,

I have a question regarding the update of a signature using PDFBox. I 
want to create a dummy signature (/Contents <000...00>), and update it 
latter with the real signature. Creating the dummy is easy, but I tried 
to update the signature and it didn't work out. Here is my code:

    byte[] signature = createRealSignature();
    PDSignature sig = doc.getLastSignatureDictionary();
    doc.saveIncremental(new FileOutputStream("signedPdf.pdf"))

Does anyone know how to do it? Do I need to set other objects as needed 
to be updated?

Thanks in advance,
