 property bool RequireDerivedKeys { bool get(); void set(bool value); };

public bool RequireDerivedKeys { get; set; }

member this.RequireDerivedKeys : bool with get, set

Public Property RequireDerivedKeys As Boolean

Property Value

Boolean

true if keys need to be derived from the token's key; otherwise, false. The default is true.

Remarks

WCF needs to derive keys from the token's key when performing signature and encryption using the token.

Derived keys originate in Secure Conversations where there is a shared security context so that the same security can be applied across all messages in the conversation. A security context token involves a shared secret, which is used for message signing and encryption. The shared secret is used to create derived keys. To maintain a high level of security through a lengthy conversation, new derived keys can be created periodically.
