Have you been able to achieve this ?
I'm in critical need of the exact same thing.
Thank you

Hi,
I'm thinking on extending the signature support by adding the ability to
'certify' a PDF. To do this I need to implement the 'Object Digest'
algorithm (you can find more information in Appendix I of the PDF
Reference for version 1.6, pages 1037 to 1044), if I want the certifying
also to work with Acrobat 6.0. Because Acrobat 6.0 requires the
DigestValue in the DocMDPTransform dictionary. To create the 'Object
Digest' you need to know the basic types of all the 'Objects' (see section
I.1 for moor information if wanted).
When I was looking to the PdfReader and PRTokeniser I found out that the
tokenizer never returns PdfBoolean objects for a boolean value, but
PdfLiterals. Can I just change the tokenizer and the reader so it creates
PdfBoolean objects if a boolean is parsed? Or does this break other stuff?
Thank you,
Nick Van den Bleeken
