Right way to do https mutual authentication based on certificates
I am working on a .net project that needs two-way https authentication based on certificates, i.e., client needs to associate requests with its own certificate and the https server can authenticate the client based on the certificate. I figured out the rough workflow but not sure if it is the right way to do it:
On the client side:
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("a request uri");
// cert is a X509Certificate2 instance from certStore or a cert file
On the server side:
// req is the HttpListenerRequest instance
if (req.ClientCertificateError == 0)
X509Certificate2 clientCert = req.GetClientCertificate;
// Validate client certificate
My questions are:
1) Is this the right way to do it?
2) On the server side, once it get the client certificate associated with the request, what does it do to validate the certificate? Assume we can install the same client certificate on the server.
