You're not using the most recent version of iText; the type of signature you're using will be deprecated in PDF 2.0. ISO-32000-2 recommends: “To support backward compatibility, PDF readers should process this value for the /SubFilter key but PDF writers shall not use this value for that key.” Please upgrade to the latest iText version and use a different type of signature. 2. The only thing you need to know, is this: you're using bad software if you're able to produce two binary identical PDF files by running the same program twice. Object numbers shouldn't matter.
