作法：使用個別 X.509 憑證簽署與加密

本主題說明如何設定 Windows Communication Foundation (WCF)，以使用不同的憑證來簽署和加密用戶端和服務上的訊息。

若要使用個別憑證進行簽署和加密，必須建立自訂用戶端和 (或) 服務憑證，因為 WCF 並未提供可以設定多個用戶端或服務憑證的 API。 此外，必須提供安全性權杖管理員才能運用多份憑證的資訊，以及建立可用於特定金鑰使用方式和訊息方向的適當安全性權杖提供者。

下方圖表會顯示所使用的主要類別、它們繼承的來源類別 (以上指標示)，以及特定方向和屬性所傳回的類別。

• MyClientCredentials 為 ClientCredentials 的自訂實作。

  • 它在圖表中所顯示的屬性都會傳回 X509Certificate2 的執行個體。

  • 它的方法 CreateSecurityTokenManager 會傳回 MyClientCredentialsSecurityTokenManager 的執行個體。

• MyClientCredentialsSecurityTokenManager 為 ClientCredentialsSecurityTokenManager 的自訂實作。

  • 它的方法 CreateSecurityTokenProvider 會傳回 X509SecurityTokenProvider 的執行個體。

如需自訂認證的詳細資訊，請參閱逐步解說：建立自訂用戶端和服務認證。

此外，您必須建立自訂身分識別驗證器，並將驗證器以自訂繫結連結到一個安全性繫結項目。 同時，不要使用預設認證，而必須使用自訂認證。

以下的圖表會顯示自訂繫結中使用的類別，以及自訂身分識別驗證器所連結的方法。 其中包含幾個繫結項目，全部都是繼承自 BindingElement。 AsymmetricSecurityBindingElement 有 LocalClientSecuritySettingsIdentityVerifier屬性，會傳回 MyIdentityVerifier(便是自訂 的來源)的執行個體。

使用用戶端上的多個憑證

1. 建立自訂繫結。 安全性繫結項目必須在雙工模式下運作，才能在要求和回應時提供不同的安全性權杖提供者。 執行這項作業的一種方法是使用具雙工能力的傳輸或使用 CompositeDuplexBindingElement，如下列程式碼所示。 將下一步所定義的自訂 IdentityVerifier 連結到安全性繫結項目。 以先前建立的自訂用戶端認證取代預設的用戶端認證。

               EndpointAddress serviceEndpoint =
                   new EndpointAddress(new Uri("http://localhost:6060/service"));

                   MessageSecurityVersion.
   WSSecurity10WSTrustFebruary2005WSSecureConversationFebruary2005WSSecurityPolicy11BasicSecurityProfile10);
               // Add a custom IdentityVerifier because the service uses two certificates
               // (one for signing and one for encryption) and an endpoint identity that
               // contains a single identity claim.
               securityBE.LocalClientSettings.IdentityVerifier = new MyIdentityVerifier();
               binding.Elements.Add(securityBE);
   
               CompositeDuplexBindingElement compositeDuplex =
                   new CompositeDuplexBindingElement();
               compositeDuplex.ClientBaseAddress = new Uri("http://localhost:6061/client");
               binding.Elements.Add(compositeDuplex);
   
               binding.Elements.Add(new OneWayBindingElement());
   
               binding.Elements.Add(new HttpTransportBindingElement());
   
               using (ChannelFactory<IMyServiceChannel> factory =
                   new ChannelFactory<IMyServiceChannel>(binding, serviceEndpoint))
               {
                   MyClientCredentials credentials = new MyClientCredentials();
                   SetupCertificates(credentials);
                   factory.Endpoint.Behaviors.Remove(typeof(ClientCredentials));
                   factory.Endpoint.Behaviors.Add(credentials);
   
                   IMyServiceChannel channel = factory.CreateChannel();
                   Console.WriteLine(channel.Hello("world"));
                   channel.Close();
               }
   

   Dim serviceEndpoint As New EndpointAddress(New Uri("http://localhost:6060/service"))

       Console.WriteLine(channel.Hello("world"))
       channel.Close()

2. 定義一個自訂的 IdentityVerifier。 服務會擁有多個識別，因為此時會使用不同的憑證來加密要求及簽署回應。

   注意

   在下列範例中所提供的自訂識別驗證器，並不會示範執行任何的端點識別檢查。 但是在實際執行程式碼 (Production Code) 中不建議這樣做。

   class MyIdentityVerifier : IdentityVerifier
   {
       IdentityVerifier defaultVerifier;
   
       public MyIdentityVerifier()
       {
           this.defaultVerifier = IdentityVerifier.CreateDefault();
       }
   
       public override bool CheckAccess(EndpointIdentity identity,
           AuthorizationContext authContext)
       {
           // The following implementation is for demonstration only, and
           // does not perform any checks regarding EndpointIdentity.
           // Do not use this for production code.
           return true;
       }
   
       public override bool TryGetIdentity(EndpointAddress reference,
           out EndpointIdentity identity)
       {
           return this.defaultVerifier.TryGetIdentity(reference, out identity);
       }
   }
   
   

   Friend Class MyIdentityVerifier
       Inherits IdentityVerifier
   
       Private defaultVerifier As IdentityVerifier
   
       Public Sub New()
           Me.defaultVerifier = IdentityVerifier.CreateDefault()
       End Sub
   
       Public Overrides Function CheckAccess(ByVal identity As EndpointIdentity, ByVal authContext As AuthorizationContext) As Boolean
           ' The following implementation is for demonstration only, and
           ' does not perform any checks regarding EndpointIdentity.
           ' Do not use this for production code.
           Return True
       End Function
   
       Public Overrides Function TryGetIdentity(ByVal reference As EndpointAddress, <System.Runtime.InteropServices.Out()> ByRef identity As EndpointIdentity) As Boolean
           Return Me.defaultVerifier.TryGetIdentity(reference, identity)
       End Function
   
   End Class
   

使用服務上的多個憑證

1. 建立自訂繫結。 安全性繫結項目必須在雙工模式下運作，才能在要求和回應時提供不同的安全性權杖提供者。 在用戶端上，使用具雙工能力的傳輸或使用 CompositeDuplexBindingElement，如下列程式碼所示。 以先前建立的自訂服務認證取代預設的服務認證。

               Uri serviceEndpoint = new Uri("http://localhost:6060/service");
               using (ServiceHost host = new ServiceHost(typeof(Service), serviceEndpoint))
               {
                   CustomBinding binding = new CustomBinding();
                   binding.Elements.Add(SecurityBindingElement.
                       CreateMutualCertificateDuplexBindingElement(
   MessageSecurityVersion.WSSecurity10WSTrustFebruary2005WSSecureConversationFebruary2005WSSecurityPolicy11BasicSecurityProfile10));
                   binding.Elements.Add(new CompositeDuplexBindingElement());
                   binding.Elements.Add(new OneWayBindingElement());
                   binding.Elements.Add(new HttpTransportBindingElement());
   
                   MyServiceCredentials credentials = new MyServiceCredentials();
                   SetupCertificates(credentials);
                   host.Description.Behaviors.Remove(typeof(ServiceCredentials));
                   host.Description.Behaviors.Add(credentials);
   
                   ServiceEndpoint endpoint = host.AddServiceEndpoint(
                       typeof(IMyService), binding, "");
                   host.Open();
   
                   Console.WriteLine("Service started, press ENTER to stop...");
                   Console.ReadLine();
               }
   

   Dim serviceEndpoint As New Uri("http://localhost:6060/service")
   Using host As New ServiceHost(GetType(Service), serviceEndpoint)
       Dim binding As New CustomBinding()
   
       With binding.Elements
           .Add(SecurityBindingElement.CreateMutualCertificateDuplexBindingElement(MessageSecurityVersion.WSSecurity10WSTrustFebruary2005WSSecureConversationFebruary2005WSSecurityPolicy11BasicSecurityProfile10))

           .Add(credentials)
       End With
   
       Dim endpoint = host.AddServiceEndpoint(GetType(IMyService), binding, "")
       host.Open()

       Console.ReadLine()
   End Using
