c# - 使用企业 CA 的 WCF SSL 证书

Question

对于一个应用程序，我需要一个 WCF 服务的 SSL 证书，

所以我们安装了它。如果我通过 https 使用带有网络浏览器的互联网浏览器，我没有任何问题，没有警告，什么都没有，所以我认为该证书被认为对 Windows 有效。

问题是，当我尝试连接到我的 WCF 服务器时，出现了这个错误:

The X.509 certificate CN=myHostName, OU=tom, O=myDomainName,

L=MyLocation, S=SO, C=CH chain building failed. The certificate that was used has a trust chain that cannot be verified. Replace the certificate or change the certificateValidationMode. The revocation function was unable to check revocation because the revocation server was offline.

有什么问题吗？我怎么知道链的哪一部分是无效的？有什么方法可以知道缺少的部分是什么？

这是我的代码服务器:

ServiceHost myHost = new ServiceHost(typeof(MyService));
WSHttpBinding binding = new WSHttpBinding
{
    ReaderQuotas = { MaxStringContentLength = int.MaxValue, MaxArrayLength = int.MaxValue, MaxDepth = int.MaxValue, MaxBytesPerRead = int.MaxValue, MaxNameTableCharCount = int.MaxValue },
    MaxReceivedMessageSize = int.MaxValue
};
TimeSpan timeoutSpan = TimeSpan.FromMilliseconds(timeout);
binding.CloseTimeout = timeoutSpan;
binding.OpenTimeout = timeoutSpan;
binding.ReceiveTimeout = timeoutSpan;
binding.SendTimeout = timeoutSpan;
binding.ReliableSession.InactivityTimeout = timeoutSpan;

binding.MaxBufferPoolSize = int.MaxValue;

//we set the security type
binding.Security.Mode = SecurityMode.Message;
binding.Security.Message.ClientCredentialType = MessageCredentialType.UserName;
binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.None;

//we set the server's certificate
myHost.Credentials.ServiceCertificate.SetCertificate(StoreLocation.LocalMachine, StoreName.My, X509FindType.FindBySubjectName, ConfigurationManager.AppSettings["Hostname"]);
myHost.Credentials.ClientCertificate.Authentication.CertificateValidationMode = X509CertificateValidationMode.None;
//we add the endPoint(and we indicate which methods are exposed through the interface

myHost.AddServiceEndpoint(services[port], binding,                  String.Format("http://localhost:{0}", port));




//Some services doesn't need an authentication
if (!servicesWithoutAuth.Contains(services[port]))
{
    //We set the authentifier:
    myHost.Credentials.UserNameAuthentication.UserNamePasswordValidationMode = UserNamePasswordValidationMode.Custom;
    myHost.Credentials.UserNameAuthentication.CustomUserNamePasswordValidator = new CustomUserNameValidator();
    myHost.Authorization.PrincipalPermissionMode = PrincipalPermissionMode.Custom;


    //we set the AuthorizationPolicy
    List<IAuthorizationPolicy> policies = new List<IAuthorizationPolicy> { new CustomAuthorizationPolicy() };
    myHost.Authorization.ExternalAuthorizationPolicies = policies.AsReadOnly();
}
else
{
    //We set the authentifier:
    myHost.Credentials.UserNameAuthentication.UserNamePasswordValidationMode = UserNamePasswordValidationMode.Custom;
    myHost.Credentials.UserNameAuthentication.CustomUserNamePasswordValidator = new NoUserNamePasswordValidator();
}

//We bypass the certificate verification(our certificate is only self signed)
//HACK Only to desactivate the SSL check: 
ServicePointManager.ServerCertificateValidationCallback += ValidateCertificate;



//HACK: Remove when debug finished
private static bool ValidateCertificate(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslpolicyerrors)
{
    return true;
}

我的客户端:

// the remote adress is of the form "net.tcp://localhost:8000"
string remoteAddress = String.Format("{0}://{1}:{2}", Tools.GetDescription(accessInfo.ServiceHost.Protocol), accessInfo.ServiceHost.HostName, accessInfo.PortNumber);

// HACK: binding depends on protocol -> switch over accessInfo.ServiceHost.Protocol

// avoid seralization/deserialization problems with large XML's
WSHttpBinding binding = new WSHttpBinding();
binding.ReaderQuotas.MaxStringContentLength = int.MaxValue;
binding.ReaderQuotas.MaxArrayLength = int.MaxValue;
binding.MaxReceivedMessageSize = int.MaxValue;
binding.ReaderQuotas.MaxStringContentLength = int.MaxValue;
binding.ReaderQuotas.MaxArrayLength = int.MaxValue;

binding.ReaderQuotas.MaxBytesPerRead = int.MaxValue;
binding.ReaderQuotas.MaxNameTableCharCount = int.MaxValue;
TimeSpan timeoutSpan = DateTime.Now.AddMinutes(30) - DateTime.Now;
binding.CloseTimeout = timeoutSpan;
binding.OpenTimeout = timeoutSpan;
binding.ReceiveTimeout = timeoutSpan;
binding.SendTimeout = timeoutSpan;
binding.ReliableSession.InactivityTimeout = timeoutSpan;


//++

binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.None;

ChannelFactory<TService> channelFactory = new ChannelFactory<TService>(binding, remoteAddress);

channelFactory.Credentials.UserName.UserName = ((UsernamePasswordAuthentication)authInfos).Username;
channelFactory.Credentials.UserName.Password = ((UsernamePasswordAuthentication)authInfos).Password;


//We set the maxItemsInObjectGraph
foreach (OperationDescription op in channelFactory.Endpoint.Contract.Operations)
{
    DataContractSerializerOperationBehavior dataContractBehavior = op.Behaviors.Find<DataContractSerializerOperationBehavior>();
    if (dataContractBehavior != null)
    {
        dataContractBehavior.MaxItemsInObjectGraph = int.MaxValue;
    }
}
SamlSecurityTokenAuthenticator authenticator = new SamlSecurityTokenAuthenticator(new List<SecurityTokenAuthenticator>(new SecurityTokenAuthenticator[] { new RsaSecurityTokenAuthenticator(), new X509SecurityTokenAuthenticator(X509CertificateValidator.None) }), TimeSpan.FromDays(5));

_service = channelFactory.CreateChannel();

How can I know which part of the chain is unvalid? Is there any way to know what is the missing part?

好吧，根据我的经验，如果您打开您的 keystore 并查看它，您应该会看到您的证书清楚地形成了一条链。我不知道您使用什么工具来查看您的 keystore (或者如果您使用的是 Windows keystore )，但是当您查看您的 key 时，您应该会看到某种链。如果一条链的形成正确，它将正确显示，并且没有任何遗漏的部分。

我的猜测是，当您导入证书回复时，由于某种原因它没有形成链。换句话说，您的证书作为“未链接”公钥存在于您的 keystore 中。
