wcf - 带有 RESTful WCF 服务的基于证书的相互 SSL

Question

我有一个基于证书的相互(双向)SSL WCF RESTful 服务，它托管在一个 Windows 应用程序中。服务器使用绑定(bind)了自签名证书的端口。该证书存在于“我的”商店的“LocalMachine”中。在同一个“我的”商店中还有客户证书。客户端和服务器证书的名称都与机器名称相同。客户端和服务器配置如下:

客户:

<system.serviceModel>
<behaviors>
  <endpointBehaviors>
    <behavior name="ClientBehavior">
      <webHttp />
      <clientCredentials>
        <clientCertificate storeLocation="LocalMachine" x509FindType="FindByThumbprint" storeName="My" findValue="F50C62754783EC741F6E84E25888D17CBC145691" />
        <serviceCertificate>
        </serviceCertificate>
      </clientCredentials>
    </behavior>
  </endpointBehaviors>
</behaviors>
<bindings>
  <webHttpBinding>
    <binding name="WebHttpBinding_Conf">
      <security mode="Transport">
        <transport clientCredentialType="Certificate"/>
      </security>
    </binding>
  </webHttpBinding>
</bindings>
<client>
  <endpoint address="https://mymachine:8088/Service" behaviorConfiguration="ClientBehavior"
      binding="webHttpBinding" bindingConfiguration="WebHttpBinding_Conf"
      contract="RESTfulLib.IService" name="WebHttpBinding_NAme" />
</client>

服务器:

  <system.serviceModel>
<behaviors>
  <endpointBehaviors>
    <behavior name="web">
      <webHttp />
    </behavior>
  </endpointBehaviors>
  <serviceBehaviors>
    <behavior name="ServiceBehavior">
      <serviceCredentials>
        <serviceCertificate storeLocation="LocalMachine" x509FindType="FindByThumbprint" findValue="7975794831242F2D39ED3B1BC8323EAF5DA2CA11" storeName="My"/>
      </serviceCredentials>
      <serviceDebug includeExceptionDetailInFaults="True"/>
    </behavior>
  </serviceBehaviors>
</behaviors>
<bindings>
  <webHttpBinding>
    <binding name="WebHttpBinding_Conf">
      <security mode="Transport">
        <transport clientCredentialType="Certificate" />
      </security>
    </binding>
  </webHttpBinding>
</bindings>
<services>
  <service name="RESTfulLib.Service" behaviorConfiguration="ServiceBehavior">
    <host>
      <baseAddresses>
        <add baseAddress="https://mymachine:8088/Service"/>
      </baseAddresses>
    </host>
    <endpoint address="" behaviorConfiguration="web" binding="webHttpBinding" bindingConfiguration="WebHttpBinding_Conf" contract="RESTfulLib.IService">
    </endpoint>
  </service>
</services>

但是，我在 SSL 握手期间收到此错误:

The HTTP request was forbidden with client authentication scheme 'Anonymous'.

启用详细的 WCF 日志显示我们在握手期间出现此错误:

System.Net Error: 0 : [11504] Decrypt returned SEC_I_RENEGOTIATE.

我试过这个设置，但这也没有帮助:

            ServicePointManager.Expect100Continue = true;
            ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3;

证书也被复制到受信任的根 CA 存储，并且有一个 ServicePointManager.ServerCertificateValidationCallback 在所有情况下都返回 true(!)

任何答案将不胜感激。谢谢!

Answer 1

由于您的证书是自签名的，因此您必须为您的客户提供一些额外的代码。

在实例化您的 WCF 客户端之前，您应该添加:

ServicePointManager.ServerCertificateValidationCallback = TrustAllCertificatesCallback;

TrustAllCertificatesCallback 是执行服务证书验证的回调方法。这是一个示例:

internal static bool TrustAllCertificatesCallback(object sender, X509Certificate cert, X509Chain chain, SslPolicyErrors errors)
{
   X509Certificate2 certificate = new X509Certificate2(cert);
   return certificate.Verify();
}

您还必须在受信任的根证书颁发机构证书存储中安装您的证书，最后添加到您的客户端端点配置:

<client>
  <endpoint address="https://mymachine:8088/Service" behaviorConfiguration="ClientBehavior"
      binding="webHttpBinding" bindingConfiguration="WebHttpBinding_Conf"
      contract="RESTfulLib.IService" name="WebHttpBinding_NAme">
    <identity>
      <dns value="<<<your certificate name>>>" />
    </identity>
  </endpoint>
</client>

您必须确保您的证书已正确安装并配置为可访问:

1. 您首先必须在本地计算机 Peronnal 存储中导入证书的私钥，而不是在当前用户的Peronnal 存储中。如果服务帐户必须使用证书，这一点很重要。

2. 如果您使用自签名证书，请确保公共(public)证书安装在本地计算机受信任的根权限存储中。

3. 允许用户访问您的证书:右键单击私有(private)证书(本地计算机/个人)，然后依次选择“所有任务”和“管理私钥”。
