How do I setup a web service to use a certificate?

[groadsvb]

I need to setup a development web service to test with. I think I can user makercert utility to create a certificate that I can use for this. Is that correct? Once I create the certificate, what do I do with it. I have a simple webservice being hosted by IIS. Can I turn it into a service that uses the certificate. Then I will create a client to access it. Thanks.
