WCF 4 - TransportWithMessageCredential 使用 X.509 证书实现传输和消息安全
我正在尝试创建一个托管在 IIS 上的 WCF4 服务,该服务将使用 X.509 证书来实现消息安全,并使用 SSL 来实现传输安全所需的相互身份验证(项目规范要求使用 WS-Security AND SSL ,据我所知通常只有一种方法,但没关系)。
我制作了 TestRootCA 并用它来颁发服务器证书 (localhost) 和客户端证书 (TestUser)。我首先只想建立和测试传输安全性,因此我将 IIS 配置为使用 https,配置了 SSL 证书(我制作的本地主机证书),并将 IIS 配置为需要来自客户端的客户端证书。然后,我修改了服务 web.config,制作了相应的 svcutil.conf 并运行了 svcutil,它成功地为我的测试 WinForms 应用程序制作了客户端代理类和 app.config。我在创建代理客户端时通过调用设置证书:
var client = new ServiceClient();
client.ClientCredentials.ClientCertificate.SetCertificate(System.Security.Cryptography.X509Certificates.StoreLocation.CurrentUser, System.Security.Cryptography.X509Certificates.StoreName.My, System.Security.Cryptography.X509Certificates.X509FindType.FindBySubjectDistinguishedName, "CN=TestUser");
MessageBox.Show(client.GetData(42));
到目前为止一切顺利。但是,当我修改服务的 web.config 以使用 TrasportWithMessageCredential(而不是 Transport)并指定“Certificate”作为消息安全性的 clientCredentialType 时,我得到 HTTP 403 - The HTTP request wasbaned with clientauthentication schema 'Anonymous'
,即使我指定了“证书”。
我的最终 web.config 如下所示:
<system.serviceModel>
<bindings>
<wsHttpBinding>
<binding name="wsHttpEndpointBinding">
<security mode="TransportWithMessageCredential">
<transport clientCredentialType="Certificate"/>
<message clientCredentialType="Certificate"/>
</security>
</binding>
</wsHttpBinding>
</bindings>
<services>
<service behaviorConfiguration="serviceBehavior" name="Service">
<endpoint binding="wsHttpBinding" bindingConfiguration="wsHttpEndpointBinding" name="wsHttpEndpoint" contract="IService" />
<endpoint address="mex" binding="wsHttpBinding" bindingConfiguration="wsHttpEndpointBinding" name="mexEndpoint" contract="IMetadataExchange" />
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="serviceBehavior">
<serviceMetadata httpsGetEnabled="true" />
<serviceDebug includeExceptionDetailInFaults="true" />
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
我的客户端 app.conf:
<system.serviceModel>
<bindings>
<wsHttpBinding>
<binding name="wsHttpEndpoint" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" bypassProxyOnLocal="false" transactionFlow="false" hostNameComparisonMode="StrongWildcard" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" messageEncoding="Text" textEncoding="utf-8" useDefaultWebProxy="true" allowCookies="false">
<readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" />
<reliableSession ordered="true" inactivityTimeout="00:10:00" enabled="false" />
<security mode="TransportWithMessageCredential">
<transport clientCredentialType="Certificate"/>
<message clientCredentialType="Certificate"/>
</security>
</binding>
</wsHttpBinding>
</bindings>
<client>
<endpoint address="https://localhost/WCFTestService/Service.svc" binding="wsHttpBinding" bindingConfiguration="wsHttpEndpoint" contract="IService" name="wsHttpEndpoint" />
</client>
</system.serviceModel>
有什么想法吗?
编辑:
我已设法通过将客户端证书的 IIS SSL 设置从要求更改为接受来使其正常工作。似乎当我在使用 SSL 的传输安全性上引入使用证书的消息安全性时,客户端使用证书进行消息签名,但不通过 SSL 进行相互身份验证(它尝试以匿名< /em> 即使它已分配了证书)。
不知道为什么会发生这种情况,我想听听专家的评论:)。
I'm trying to make a WCF4 service hosted on IIS which will use X.509 certificates for message security and SSL with required mutual authentication for transport security (project specification requires the use of WS-Security AND SSL, AFAIK only one is usually the way to go, but never mind).
I made my TestRootCA and used it to issue a server certificate (localhost) and a client certificate (TestUser). I first wanted to establish and test transport security only, so I configured IIS to use https, configured SSL certificate (localhost cert that I made), and configured IIS to require a client certificate from clients. I then modified service web.config, made the corresponding svcutil.conf and ran svcutil that successfully made client proxy class and app.config for my test WinForms app. I set the certificate when creating proxy client by calling:
var client = new ServiceClient();
client.ClientCredentials.ClientCertificate.SetCertificate(System.Security.Cryptography.X509Certificates.StoreLocation.CurrentUser, System.Security.Cryptography.X509Certificates.StoreName.My, System.Security.Cryptography.X509Certificates.X509FindType.FindBySubjectDistinguishedName, "CN=TestUser");
MessageBox.Show(client.GetData(42));
So far so good. But when I modify service's web.config to use TrasportWithMessageCredential (instead of Transport) and specify "Certificate" as the clientCredentialType for message security I get HTTP 403 - The HTTP request was forbidden with client authentication scheme 'Anonymous'
, even though I specified "Certificate".
My final web.config looks like this:
<system.serviceModel>
<bindings>
<wsHttpBinding>
<binding name="wsHttpEndpointBinding">
<security mode="TransportWithMessageCredential">
<transport clientCredentialType="Certificate"/>
<message clientCredentialType="Certificate"/>
</security>
</binding>
</wsHttpBinding>
</bindings>
<services>
<service behaviorConfiguration="serviceBehavior" name="Service">
<endpoint binding="wsHttpBinding" bindingConfiguration="wsHttpEndpointBinding" name="wsHttpEndpoint" contract="IService" />
<endpoint address="mex" binding="wsHttpBinding" bindingConfiguration="wsHttpEndpointBinding" name="mexEndpoint" contract="IMetadataExchange" />
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="serviceBehavior">
<serviceMetadata httpsGetEnabled="true" />
<serviceDebug includeExceptionDetailInFaults="true" />
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
and my client app.conf:
<system.serviceModel>
<bindings>
<wsHttpBinding>
<binding name="wsHttpEndpoint" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" bypassProxyOnLocal="false" transactionFlow="false" hostNameComparisonMode="StrongWildcard" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" messageEncoding="Text" textEncoding="utf-8" useDefaultWebProxy="true" allowCookies="false">
<readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" />
<reliableSession ordered="true" inactivityTimeout="00:10:00" enabled="false" />
<security mode="TransportWithMessageCredential">
<transport clientCredentialType="Certificate"/>
<message clientCredentialType="Certificate"/>
</security>
</binding>
</wsHttpBinding>
</bindings>
<client>
<endpoint address="https://localhost/WCFTestService/Service.svc" binding="wsHttpBinding" bindingConfiguration="wsHttpEndpoint" contract="IService" name="wsHttpEndpoint" />
</client>
</system.serviceModel>
Any ideas?
EDIT:
I've managed to get it working by changing IIS SSL settings for Client certificate from require to accept. It seems that when I introduce message security using certificates over transport security using SSL, the client uses the certificate for message signing but not for mutual authentication over SSL (it tries to log on as anonymous even though it has a certificate assigned).
Not sure why this is happening, I'd like some comment from an expert :).

正如问题中所述,我通过将客户端证书的 IIS SSL 设置从
require
更改为accept
来使其工作。然后在服务入口点中,我以编程方式检查远程用户的证书(如果其不为空且有效)。As stated in the question, I got it working by changing IIS SSL settings for Client certificates from
require
toaccept
. Then in the service entry point I programmaticaly check the remote user's certificate (if its not null and valid).您必须在行为部分中指定用于加密消息的证书,因为这些证书可能与用于建立 https 通道的证书不同,
它在服务器中看起来像这样
,在客户端中也是如此,看起来像这样
当然,您必须在服务器和客户端中设置证书的正确位置和名称。
我希望这仍然有帮助
You must specify the certificates to use to encrypt the message in the behavior section since these could be different as the ones used to establish the https channel
it would look like this in the server
and do the same in the client, that would look like this
Off course, you have to set the right location and name of the certificates, in the server and client.
I hope this still helps
