Hi everyone!!! I have a problem and hope someone can help me.
I have a PDF form accessed via a secure connection which requires the user to identify himself using a digital certificate, and the PDF has to be signed in order to be sent and processed by a J2EE application.
When I receive the signed PDF, I must verify that the certificate used to sign the PDF is the same that was used to access the web page. I can get the certificate used to access the web from the session; but I have no idea of how can I extract the certificate from the PDF, I can access the date contained in the PDF but I don't see the node where the certificate is stored(in case it is stored).
Thanks in advance for the help.
