使用相互证书的消息安全
下面的方案演示使用消息安全模式保护的 Windows Communication Foundation (WCF) 服务和客户端。使用证书对客户端和服务进行身份验证。
本方案是可互操作的，因为它使用具有 X.509 证书令牌配置文件的 WS-Security。

|---|
| 本方案不对服务证书执行协商。在进行任何通信之前，必须先向客户端提供服务证书。服务器证书可以随应用程序一起分发，也可以通过带外通信来提供。 |

服务
下面的代码和配置将独立运行。执行下列操作之一：
使用代码（而不使用配置）创建独立服务。
使用提供的配置创建服务，但不定义任何终结点。
代码
下面的代码演示如何创建使用消息安全的服务终结点。服务请求一个证书来使自己通过身份验证。
' Create the binding.
Dim binding As New WSHttpBinding()
binding.Security.Mode = SecurityMode.Message
binding.Security.Message.ClientCredentialType = _
MessageCredentialType.Certificate
binding.Security.Message.NegotiateServiceCredential = False
binding.Security.Message.EstablishSecurityContext = False
' Create the URI for the endpoint.
Dim httpUri As New Uri("https://localhost/Calculator")
' Create the service host.
Dim myServiceHost As New ServiceHost(GetType(ServiceModel.Calculator), httpUri)
' Specify a certificate to authenticate the service.
myServiceHost.Credentials.ServiceCertificate.SetCertificate(StoreLocation.LocalMachine, _
StoreName.My, X509FindType.FindBySubjectName, "contoso.com")
' Add an endpoint to the service.
myServiceHost.AddServiceEndpoint(GetType(ICalculator), binding, "")
' Open the service.
myServiceHost.Open()
Console.WriteLine("Listening...")
Console.ReadLine()
' Close the service.
myServiceHost.Close()
// Create the binding.
WSHttpBinding binding = new WSHttpBinding();
binding.Security.Mode = SecurityMode.Message;
binding.Security.Message.ClientCredentialType =
MessageCredentialType.Certificate;
binding.Security.Message.NegotiateServiceCredential = false;
binding.Security.Message.EstablishSecurityContext = false;
// Create the URI for the endpoint.
Uri httpUri = new Uri("https://localhost/Calculator");
// Create the service host.
ServiceHost myServiceHost =
new ServiceHost(typeof(Calculator), httpUri);
// Specify a certificate to authenticate the service.
myServiceHost.Credentials.ServiceCertificate.SetCertificate(
StoreLocation.LocalMachine,
StoreName.My,
X509FindType.FindBySubjectName,
"contoso.com");
// Add an endpoint to the service.
myServiceHost.AddServiceEndpoint(typeof(ICalculator), binding, "");
// Open the service.
myServiceHost.Open();
Console.WriteLine("Listening...");
Console.ReadLine();
// Close the service.
myServiceHost.Close();
配置
可以使用下面的配置，而不使用代码来创建同样的服务。
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<system.serviceModel>
<behaviors>
<serviceBehaviors>
<behavior name="serviceCredentialBehavior">
<serviceCredentials>
<serviceCertificate findValue="Contoso.com"
storeLocation="LocalMachine"
storeName="My"
x509FindType="FindBySubjectName" />
</serviceCredentials>
</behavior>
</serviceBehaviors>
</behaviors>
<services>
<service behaviorConfiguration="serviceCredentialBehavior"
name="ServiceModel.Calculator">
<endpoint address="https://localhost/Calculator"
binding="wsHttpBinding"
bindingConfiguration="InteropCertificateBinding"
name="WSHttpBinding_ICalculator"
contract="ServiceModel.ICalculator" />
</service>
</services>
<bindings>
<wsHttpBinding>
<binding name="InteropCertificateBinding">
<security mode="Message">
<message clientCredentialType="Certificate"
negotiateServiceCredential="false"
establishSecurityContext="false" />
</security>
</binding>
</wsHttpBinding>
</bindings>
<client />
</system.serviceModel>
</configuration>
客户端
下面的代码和配置将独立运行。执行下列操作之一：
使用代码（和客户端代码）创建独立客户端。
创建不定义任何终结点地址的客户端。而使用将配置名称作为参数的客户端构造函数。例如：
Dim cc As New CalculatorClient("EndpointConfigurationName")CalculatorClient cc = new CalculatorClient("EndpointConfigurationName");
代码
下面的代码创建客户端。安全模式设置为“消息”，客户端凭据类型设置为“证书”。
' Create the binding.
Dim myBinding As New WSHttpBinding()
myBinding.Security.Mode = SecurityMode.Message
myBinding.Security.Message.ClientCredentialType = MessageCredentialType.Certificate
' Disable credential negotiation and the establishment of
' a security context.
myBinding.Security.Message.NegotiateServiceCredential = False
myBinding.Security.Message.EstablishSecurityContext = False
' Create the endpoint address.
Dim ea As New EndpointAddress("https://localhost/Calculator")
' Create the client.
Dim cc As New CalculatorClient(myBinding, ea)
' Specify a certificate to use for authenticating the client.
cc.ClientCredentials.ClientCertificate.SetCertificate( _
StoreLocation.CurrentUser, StoreName.My, _
X509FindType.FindBySubjectName, "Cohowinery.com")
' Specify a default certificate for the service.
cc.ClientCredentials.ServiceCertificate.SetDefaultCertificate( _
StoreLocation.CurrentUser, StoreName.TrustedPeople, _
X509FindType.FindBySubjectName, "Contoso.com")
' Begin using the client.
Try
cc.Open()
Console.WriteLine(cc.Add(100, 11))
Console.ReadLine()
' Close the client.
cc.Close()
Catch tex As TimeoutException
Console.WriteLine(tex.Message)
cc.Abort()
Catch cex As CommunicationException
Console.WriteLine(cex.Message)
cc.Abort()
Finally
Console.WriteLine("Closed the client")
Console.ReadLine()
End Try
// Create the binding.
WSHttpBinding myBinding = new WSHttpBinding();
myBinding.Security.Mode = SecurityMode.Message;
myBinding.Security.Message.ClientCredentialType =
MessageCredentialType.Certificate;
// Disable credential negotiation and the establishment of
// a security context.
myBinding.Security.Message.NegotiateServiceCredential = false;
myBinding.Security.Message.EstablishSecurityContext = false;
// Create the endpoint address.
EndpointAddress ea = new
EndpointAddress("http://machineName/Calculator");
// Create the client.
CalculatorClient cc =
new CalculatorClient(myBinding, ea);
// Specify a certificate to use for authenticating the client.
cc.ClientCredentials.ClientCertificate.SetCertificate(
StoreLocation.CurrentUser,
StoreName.My,
X509FindType.FindBySubjectName,
"Cohowinery.com");
// Specify a default certificate for the service.
cc.ClientCredentials.ServiceCertificate.SetDefaultCertificate(
StoreLocation.CurrentUser,
StoreName.TrustedPeople,
X509FindType.FindBySubjectName,
"Contoso.com");
// Begin using the client.
try
{
cc.Open();
Console.WriteLine(cc.Add(200, 1111));
Console.ReadLine();
// Close the client.
cc.Close();
}
