I have a WCF service which accepts X.509 certificate signed incoming messages. As per my understanding the client will send the message with signature encrypted using his private key and web services will decrypt the signature with client's public key. This ensures that the sender of the message is holder of the private key and that he is certified by the server trusted CA as "He is what he claims to be".
It's being a highly secure application I need to give access to only certain clients regardless of whether they are trusted or not. (This is to take care of good turned bad scenario :-)) How do I achieve this? Is there any way to get the client information as subject name etc from his certificate in C# code? Is there any example of this usage?
Thanks in advance,Jeet.
