AsymmetricSecurityBindingElement Class
Represents a custom binding element that supports channel security using asymmetric encryption. This binding element signs the message using the sender's authentication token and encrypts the message using the recipient's token.

The AsymmetricSecurityBindingElement type exposes the following members.
| Name | Description | |
|---|---|---|
|
AsymmetricSecurityBindingElement() | Creates an instance of this class. |
|
|
AsymmetricSecurityBindingElement(SecurityTokenParameters) | Initializes a new instance of AsymmetricSecurityBindingElement with the specified recipient token parameters. |
|
|
AsymmetricSecurityBindingElement(SecurityTokenParameters, SecurityTokenParameters) | Initializes a new instance of AsymmetricSecurityBindingElement with the specified recipient and initiator token parameters. |
| Name | Description | |
|---|---|---|
|
AllowInsecureTransport | Gets or sets a value that indicates whether mixed-mode secured messages can be sent over an unsecured transport such as HTTP. (Inherited from SecurityBindingElement.) |
|
|
AllowSerializedSigningTokenOnReply | Gets or sets a value that indicates whether serializing a signing token on a reply message is allowed. |
|
|
DefaultAlgorithmSuite | Gets or sets the message encryption and key-wrap algorithms. (Inherited from SecurityBindingElement.) |
|
|
EnableUnsecuredResponse | Gets or sets a value that indicates whether can send and receive unsecured responses to secured requests. (Inherited from SecurityBindingElement.) |
|
|
EndpointSupportingTokenParameters | Gets the endpoint that supports token parameters. (Inherited from SecurityBindingElement.) |
|
|
IncludeTimestamp | Gets or sets a value that indicates whether time stamps are included in each message. (Inherited from SecurityBindingElement.) |
|
|
InitiatorTokenParameters | Specifies the token definition for the initiator. |
|
|
KeyEntropyMode | Gets or sets the source of entropy used to create keys. (Inherited from SecurityBindingElement.) |
|
|
LocalClientSettings | Gets the binding properties specific to local security settings used by the client. (Inherited from SecurityBindingElement.) |
|
|
LocalServiceSettings | Gets the binding properties specific to local security settings used by the service. (Inherited from SecurityBindingElement.) |
|
|
MessageProtectionOrder | Gets or sets the order of message encryption and signing for this binding. |
|
|
MessageSecurityVersion | Gets or sets the message security version. (Inherited from SecurityBindingElement.) |
|
|
OperationSupportingTokenParameters | Gets the collection of operation supporting token parameters. (Inherited from SecurityBindingElement.) |
|
|
OptionalEndpointSupportingTokenParameters | Gets the optional supporting token parameters for the service endpoint. (Inherited from SecurityBindingElement.) |
|
|
OptionalOperationSupportingTokenParameters | Gets the collection of optional operation supporting token parameters. (Inherited from SecurityBindingElement.) |
|
|
RecipientTokenParameters | Specifies the token definition for the recipient. |
|
|
RequireSignatureConfirmation | Gets or sets a value that indicates whether message signatures must be confirmed. |
|
|
SecurityHeaderLayout | Gets or sets the ordering of the elements in the security header for this binding. (Inherited from SecurityBindingElement.) |
| Name | Description | |
|---|---|---|
|
|
BuildChannelFactory<TChannel> | Creates a channel factory based on the SecurityBindingElement settings and the binding context passed in. The channel factory created is a SOAP message security channel factory, which internally has a reference to the channel factory that corresponds to the binding context, (which includes the transport channel factory). (Inherited from SecurityBindingElement.) |
|
BuildChannelFactoryCore<TChannel> | When implemented, creates a channel factory of a specified type. (Inherited from SecurityBindingElement.) |
|
|
BuildChannelListener<TChannel> | Creates a channel listener based on the SecurityBindingElement settings and the binding context passed in. (Inherited from SecurityBindingElement.) |
|
|
BuildChannelListenerCore<TChannel> | When implemented, creates a channel listener of a specified type. (Inherited from SecurityBindingElement.) |
|
|
CanBuildChannelFactory<TChannel> | Gets a value that indicates whether a channel factory of the specified type can be built. (Inherited from SecurityBindingElement.) |
|
|
CanBuildChannelListener<TChannel> | Gets a value that indicates whether a channel listener of the specified type can be built. (Inherited from SecurityBindingElement.) |
|
|
Clone | Creates a new instance of this class initialized from the current one. (Overrides BindingElement.Clone().) |
|
|
Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
|
|
Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
|
|
GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
|
|
GetProperty<T> | Gets a specified object from the BindingContext. (Overrides SecurityBindingElement.GetProperty<T>(BindingContext).) |
|
|
GetType | Gets the Type of the current instance. (Inherited from Object.) |
|
|
MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
|
|
SetKeyDerivation | Sets a value that indicates whether derived keys are required. (Overrides SecurityBindingElement.SetKeyDerivation(Boolean).) |
|
|
ToString | Returns a string that represents this AsymmetricSecurityBindingElement instance. (Overrides SecurityBindingElement.ToString().) |
| Name | Description | |
|---|---|---|
|
IPolicyExportExtension.ExportPolicy | Exports a custom policy assertion about bindings, which is added to the Web Services Description Language (WSDL) information. |
A custom binding contains a collection of binding elements arranged in a specific order: the element that represents the top of the binding stack is added first, the next element down in the binding stack, is added second, and so forth.
To add this class to a binding
-
Create a BindingElementCollection.
-
Create custom binding elements that is above this binding element in the binding stack, such as the optional TransactionFlowBindingElement and ReliableSessionBindingElement.
-
Add the created elements in the preceding order to the BindingElementCollection using the InsertItem(Int32, BindingElement) method.
-
Create an instance of AsymmetricSecurityBindingElement and add it to the collection.
-
Add any additional custom binding elements to the collection, such as TcpTransportBindingElement.
Before using this class, you should determine if a standard binding meets your security requirements.
Note

|
Once an instance of this object is created, you should treat the properties of its base class SecurityBindingElement as immutable. Calling set on some properties may have unpredictable effects: the binding may behave as if the property retained its old value, with a run-time failure being the only indication of an issue. Two properties known to behave this way are KeyType and MessageSecurityVersion. There may be other properties this is true of. |
The following example shows how to use this class to create a custom binding that includes this class as a security binding element. For more information about the code in this example, see How To: Reference X.509 Certificates Consistently.
public Binding CreateClientBinding() { //<snippet2> AsymmetricSecurityBindingElement abe = (AsymmetricSecurityBindingElement)SecurityBindingElement. CreateMutualCertificateBindingElement( MessageSecurityVersion. WSSecurity10WSTrustFebruary2005WSSecureConversationFebruary2005WSSecurityPolicy11BasicSecurityProfile10); abe.SetKeyDerivation(false); X509SecurityTokenParameters istp = abe.InitiatorTokenParameters as X509SecurityTokenParameters; if (istp != null) { istp.X509ReferenceStyle = X509KeyIdentifierClauseType.IssuerSerial; } X509SecurityTokenParameters rstp = abe.RecipientTokenParameters as X509SecurityTokenParameters; if (rstp != null) { rstp.X509ReferenceStyle = X509KeyIdentifierClauseType.IssuerSerial; } HttpTransportBindingElement transport = new HttpTransportBindingElement(); return new CustomBinding(abe, transport); }
