C# Get the Client Application Checksum from the WCF Service

We are using WCF Services that transfer some data from a Client Application to the Server Application (WCF Service). This last one will apply an algorithm using these data and send back the result to the client.

We would like to authenticate the Client Application from the Serv开发者_StackOverflow中文版er WCF Service. Would it be possible to get the Client Application Checksum directly from the WCF Service?

We are already using wsHttpBinding but we would like to add one more layer on the client application integrity.

Appreciate for your help, Camille.

he WCF service can't get anything from the client unless the client sends it to the service. So if you can get your client to send your service the checksum (as a method parameter), then you're in business. WCF is not magic. Nor is any "service" technology for that matter. It is a simple tcp/ip communication between a client and a server. On both side, the only information that goes across is the information each side decides to send, nothing more.
