How to embedd author certificate and user digital signature?

Question

Hi,
I want to implement Digital Signature in my pdf using Netweaver technology. I am working on an offline scenario.
I have few question on this topic.
1) Once I sign the pdf do the input-fields in them get locked? Is no then how do I lock them to ensure that they are not tampered?
2) How to pass the certificate along with the pdf? Can I pass it through an email?
3) Is the digital signature completely done on Adobe Reader side or the program side?
Please reply urgently...
Thanks,
Vishal

hi
i've the same problem. i've found this solution, but you need download a JCE Provider that allow you to read the explorer certificate store.
You can try this one: https://download.assembla.se/jceprovider/
and the code:
import se.assembla.*;
public class Listcerts {  
     public static void list() throws Exception{
          java.security.Security.insertProviderAt(new se.assembla.jce.provider.ms.MSProvider(), 2);
          KeyStore ks = KeyStore.getInstance("MSKS","assembla");
          ks.load(null,null);
          X509Certificate cert=null;
          String alias=null;
          int count=0;
          for (java.util.Enumeration e=ks.aliases();e.hasMoreElements();){
                    alias=(String)e.nextElement();
                    cert=(X509Certificate)ks.getCertificate(alias);
                    System.out.println("\n Certificado alias"+alias+":");
                    System.out.println(cert);
               count++;
          System.out.println ("NUM CERTS="+count);
now, i need the same solution for Firefox browser XP
good luck
