WPF

<br />
Since in the Internet scenario the client's message is transferred to the service over plain HTTP, it is vital to protect its content (both the client's credentials and the body of the message) by encrypting it. Encryption will provide for message integrity and privacy...<br />
Once the message is decrypted, WCF will read the client's credentials from the message, authenticate the client, and allow it to access the service. The real picture is a bit more complex, because WCF also needs to secure the reply messages and callbacks from the service to the client. One of the standards WCF supports deals with setting up such a secure conversation. In fact, several calls are made before the first request message from the client to the service, where WCF on the client's side generates a temporary shared secret it passes encrypted (using the service certificate) to the service. The client and the service will use that shared secret to protect all subsequent communication between them.<br />
