Enter a friendly name for the new certificate and click OK.
Now you have a self-signed certificate. The certificate is marked for “Server Authentication” use; that is, it uses as a server-side certificate for HTTP SSL encryption and for authenticating the identity of the server.
Select a site in the tree view and click Bindings… in the Actions pane. This brings up the bindings editor that lets you create, edit, and delete bindings for your Web site. Click Add… to add your new SSL binding to the site.
The default settings for a new binding are set to HTTP on port 80. Select https in the Type drop-down list. Select the self-signed certificate you created in the previous section from the SSL Certificate drop-down list and then click OK.
Internet Explorere (IE) 7 and above will display an error page because the self-signed certificate was issued by your computer, not by a trusted Certificate Authority (CA). IE 7 and above will trust the certificate if you add it to the list of Trusted Root Certification Authorities in the certificates store it on the local computer, or in Group Policy for the domain.
