I'd like to know more about PDFs with Digital Signatures.

I have three points :

1) Maybe someone else could offer to us an example ? So that we could open inside Acrobat and verify the Digital Signature ?

2) I can use QuickPDF to "sign" the PDFs I generate on-the-fly ?

3) What do I need to use as "ink" to sign my PDFs ? Is it possible to use my http server SSL certificate to sign the PDFs or do I need a special purpose certificate for doing that ?

TIA !

Hi,

    Unfortunately, QuickPDF does not support digital signatures. In 2004, iSed was "working" on a PDF digital signature tool, but it was never completed or published.

    If you are looking to apply digital signatures to a PDF file, then you need to look at a different library other thatn QuickPDF. The library that I resell does offer some digital signature support. See [ http://www.exp-systems.com/DynaPDF/Features.htm - here ]. Apart from that, there are other options, but you will need to search for them on the internet.

    Cheers!
