Dear List, Not sure which forum to post this to, so if its o/t I appologise. I'm aware of how SSL generates a one-time certificate for encrypted browsing client->server. Is it possible, to install a certificate on the server and a corresponding certificate on the client, so only clients holding this certificate can use the web-server? If this is do-able, are there any links which would assist me in generating and installing the keys. Regards, Chris A.
