<message> of <basicHttpBinding>

Defines the settings for message-level security of the <basicHttpBinding>.


The following sections describe attributes, child elements, and parent elements


Attribute Description


Sets the message encryption and key-wrap algorithms. This attribute is of type SecurityAlgorithmSuite, which specifies the algorithms and the key sizes. These algorithms map to those specified in the Security Policy Language (WS-SecurityPolicy) specification.

The default value is Basic256.


Specifies the type of credential to be used when performing client authentication using message-based security. The default is UserName.

Element Description

<security> of <basicHttpBinding>

Defines the security capabilities for the <basicHttpBinding>.

This sample demonstrates how to implement an application that uses the basicHttpBinding and message security. In the following configuration example for a service, the endpoint definition specifies the basicHttpBinding and references a binding configuration named Binding1. The certificate that the service uses to authenticate itself to the client is set in the behaviors section of the configuration file under the serviceCredentials element. The validation mode that applies to the certificate that the client uses to authenticate itself to the service is also set in the behaviors section under the clientCertificate element.

The same binding and security details are specified in the client configuration file.

      <service name="Microsoft.ServiceModel.Samples.CalculatorService"
            <add baseAddress="http://localhost:8000/ServiceModelSamples/service"/>
        <!-- this endpoint is exposed at the base address provided by host: http://localhost:8000/ServiceModelSamples/service  -->
        <endpoint address=""
                  contract="Microsoft.ServiceModel.Samples.ICalculator" />
        <!-- the mex endpoint is exposed at http://localhost:8000/ServiceModelSamples/service/mex -->
        <endpoint address="mex"
                  contract="IMetadataExchange" />

        This configuration defines the SecurityMode as Message and 
        the clientCredentialType as Certificate.
        <binding name="Binding1" >
          <security mode = "Message">
            <message clientCredentialType="Certificate"/>

    <!--For debugging purposes set the includeExceptionDetailInFaults attribute to true-->
        <behavior name="CalculatorServiceBehavior">
          <serviceMetadata httpGetEnabled="True"/>
          <serviceDebug includeExceptionDetailInFaults="False" />
        The serviceCredentials behavior allows one to define a service certificate.
        A service certificate is used by a client to authenticate the service and provide message protection.
        This configuration references the "localhost" certificate installed during the setup instructions.
            <serviceCertificate findValue="localhost" storeLocation="LocalMachine" storeName="My" x509FindType="FindBySubjectName" />
            Setting the certificateValidationMode to PeerOrChainTrust means that if the certificate 
            is in the user's Trusted People store, then it will be trusted without performing a
            validation of the certificate's issuer chain. This setting is used here for convenience so that the 
            sample can be run without having to have certificates issued by a certificate authority (CA).
            This setting is less secure than the default, ChainTrust. The security implications of this 
            setting should be carefully considered before using PeerOrChainTrust in production code. 
              <authentication certificateValidationMode="PeerOrChainTrust" />
