HttpDigestClientCredential Class

Used for digest authentication of HTTP clients.

Namespace:  System.ServiceModel.Security
Assembly:  System.ServiceModel (in System.ServiceModel.dll)

public sealed class HttpDigestClientCredential

Digest authentication verifies that both parties to a communication know a shared secret (a password). Authentication is done without sending the password in the clear. Digest authentication is based on a challenge-response paradigm. The Digest scheme challenges using a nonce ("number used once") value. The response must contain a checksum of the user name, the password, the nonce value, the HTTP method, and the requested URI.
