SymmetricSecurityBindingElement.MessageProtectionOrder Property

Gets or sets the order of message encryption and signing for this binding.

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

public MessageProtectionOrder MessageProtectionOrder { get; set; }

Property Value

Type: System.ServiceModel.Security.MessageProtectionOrder
The MessageProtectionOrder that specifies how the message is protected. The default is SignBeforeEncrypt.

ExceptionCondition
ArgumentOutOfRangeException

set and value is undefined.

NoteNote:

If there is nothing in the message that is encrypted, the signature element is not encrypted even when the MessageProtectionOrder property is set to SignBeforeEncryptAndEncryptSignature. This behavior occurs even with system-provided bindings. However, the WSDL generated by WCF still contains the <sp:EncryptSignature> assertion.

For a listing of the members and their descriptions, see MessageProtectionOrder.

The following code shows how to set this property.

// Create a SymmetricSecurityBindingElement.
SymmetricSecurityBindingElement ssbe = 
    new SymmetricSecurityBindingElement();

// Set the algorithm suite to one that uses 128-bit keys.
ssbe.DefaultAlgorithmSuite = SecurityAlgorithmSuite.Basic128;

   // Set MessageProtectionOrder to SignBeforeEncrypt.
ssbe.MessageProtectionOrder = MessageProtectionOrder.SignBeforeEncrypt;
