Creating a PDF with a digital signature

[Marco Steybe <ma...@nurfuerspam.de>]

Hi there,

I'm evaluating PDFBox for a project which needs to create PDF docs on the fly and support digital signatures. I found the class org.apache.pdfbox.pdmodel.interactive.digitalsignature.PDSignature but I'm not sure how to use it. Do you have any sample code? Or can anyone give me some ideas how I can create a PDF with a digital signature using PDFBox?

Thanks a lot!

Marco,

I think you will be interested in PDFBOX-912[1] which is a work in 
progress.  I reviewed all the code and found that it uses a huge array to 
store the entire document in order to sign it, but other than that it 
looks good.  We can change it to use streams instead of byte arrays, but 
that changes the proposed API and would break Thomas's code (which is 
outside of PDFBox).

I haven't been able to test it because I don't have any code to do the 
signing, just the API which lets external programs sign documents. 
Thomas's current signature code can not be added to PDFBox due to 
copyright, but he'll add a small example for basic signatures when he gets 
time.

Thanks,
Adam
