如何执行 ssl 用户身份验证

Question

自签名证书用于 WCF 应用程序中的身份验证。指定的服务器：

<security mode="Message">
    <message clientCredentialType="Certificate"/>
</security>
...
<clientCertificate>
  <authentication certificateValidationMode="PeerOrChainTrust" revocationMode="NoCheck"/>
</clientCertificate>

证书已在客户端正确启用：

<endpointBehaviors>
<behavior name="wsHttpCertificateBehavior">          
  <clientCredentials>
    <clientCertificate findValue="<Thumbprint>" storeName="My" storeLocation="LocalMachine" x509FindType="FindByThumbprint"/>    
  </clientCredentials>          
</behavior>
</endpointBehaviors>

在客户端，证书被添加到受信任的根证书中。调用服务方法时出现错误：调用用户的身份未经服务验证。我不明白您还需要指定什么进行验证。如果您删除证书并指定

<security mode= "None"/>

调用服务方法时客户端挂起。我不明白为什么。我已经为此奋斗了一周。请帮帮我！

这是一个使用 X.509 自签名证书验证的演示：

<system.serviceModel>
    <services>
      <service name="Microsoft.Samples.X509CertificateValidator.CalculatorService" behaviorConfiguration="CalculatorServiceBehavior">
        <!-- use host/baseAddresses to configure base address provided by host -->
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:8001/servicemodelsamples/service"/>
          </baseAddresses>
        </host>
        <!-- use base address specified above, provide one endpoint -->
        <endpoint address="certificate" binding="wsHttpBinding" bindingConfiguration="Binding" contract="Microsoft.Samples.X509CertificateValidator.ICalculator"/>
      </service>
    </services>

    <bindings>
      <wsHttpBinding>
        <!-- X509 certificate binding -->
        <binding name="Binding">
          <security mode="Message">
            <message clientCredentialType="Certificate"/>
          </security>
        </binding>
      </wsHttpBinding>
    </bindings>

    <behaviors>
      <serviceBehaviors>
        <behavior name="CalculatorServiceBehavior">
          <serviceDebug includeExceptionDetailInFaults="true"/>
          <serviceCredentials>
            <!-- 
            The serviceCredentials behavior allows one to specify authentication constraints on client certificates.
            -->
            <clientCertificate>
              <!-- 
              Setting the certificateValidationMode to Custom means that if the custom X509CertificateValidator
              does NOT throw an exception, then the provided certificate will be trusted without performing any
              validation beyond that performed by the custom validator. The security implications of this 
              setting should be carefully considered before using Custom in production code. 
              -->
              <authentication certificateValidationMode="Custom" customCertificateValidatorType="Microsoft.Samples.X509CertificateValidator.CustomX509CertificateValidator, service"/>
            </clientCertificate>
            <!-- 
            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"/>
          </serviceCredentials>
        </behavior>
      </serviceBehaviors>
    </behaviors>
    
  </system.serviceModel>

这是服务的配置文件，我们需要指定证书的位置。

serviceHost.Credentials.ClientCertificate.Authentication.CertificateValidationMode = System.ServiceModel.Security.X509CertificateValidationMode.Custom;
              
serviceHost.Credentials.ClientCertificate.Authentication.CustomCertificateValidator = new CustomX509CertificateValidator();

我们自定义验证自签名证书。

public class CustomX509CertificateValidator : System.IdentityModel.Selectors.X509CertificateValidator
    {
        // This Validation function accepts any X.509 Certificate that is self-issued. As anyone can construct such
        // a certificate this custom validator is less secure than the default behavior provided by the
        // ChainTrust X509CertificateValidationMode. The security implications of this should be carefully 
        // considered before using this validation logic in production code. 
        public override void Validate(X509Certificate2 certificate)
        {
            // Check that we have been passed a certificate
            if (certificate == null)
                throw new ArgumentNullException("certificate");

            // Only accept self-issued certificates
            if (certificate.Subject != certificate.Issuer)
                throw new SecurityTokenException("Certificate is not self-issued");
        }
    }
