Hi.
Really need your help on this one. 
How do you retrieve user's x509 v3 certificate from an IE 5.0 through the 
use of servlets?

I'm using JDK 1.3.1, IAIK_JCE_FULL.jar.

I've tried using this code

X509Certificate cert = (iaik.x509.X509Certificate)req.getAttribute
("javax.servlet.req.X509Certificate);

It returns a null.

Thank you very much.

Mel
