Hello from an ASP Newbie.<BR><BR>I am exploring ways to connect an IIS to an OCSP Responder to check whether a Client Certificate supplied during an SSL connection has been revoked. I am aware that I can get the Issuuer Name and the Certificate&#039;s Serial Number by accessing the Request.ServerVariable() object, but I need the issuing CA&#039;s public key as well to form an OCSP Request message, per RFC 2560.<BR><BR>Does anyone know how to access the entire Client Certificate using ASP. Should I consider a solution using ISAPI extensions instead?<BR><BR>TIA,<BR><BR>Dave Button<BR>general Dynamics Comunication Systems
