I have the following scenario - Client Cert -- Tunnel Server - Tunnel Client -- Backend server. The requirement is to pass the Client Cert to the Backend server. If you could do that then anyone who had access to a certificate (for example the recipent of signed email) could

All this talk about trying to gateway client certs has got me thinking about something I saw last week in the PGP-8.0 docs. They have this concept of additional decryption keys. Apparently you can configure PGP so that even though you are the only one with your key-pair, when you encrypt a

It seems I have not explained myself ably. I completly understand that Private Keys should and would never be sent across. But assume that you are going through a proxy using SSL. And the proxy has no capability to verify the certs. That capablity is vested with a server that sits behind the
