如何使WCF客户端符合特定的WS-Security - 签署UsernameToken和SecurityTokenReference

标签： c# wcf x509certificate ws-security

我需要创建一个wcf客户端来调用我无法控制的服务。

我获得了一个wsdl和一个有效的soapui项目。

该服务使用用户名/密码和x509证书。

更新

我现在明白问题是什么，但我仍然不确定我需要采取哪些步骤才能创建所需的消息，所以任何帮助都会非常感激。

我需要同时签署UsernameToken和SecurityTokenReference。

由于不再使用，我必须从此帖子中删除我必须创建自定义绑定的代码。我不再向绑定添加SecurityBindingElement，而是添加一个将安全元素写入标头的新行为。

因此，通过继承SignedXml类，添加签名引用，然后调用ComputeSignature以在Security头中创建Signature节点，从头开始创建安全节点。

您需要传递xml以登录SignedXml构造函数才能使其生效。传递UsernameToken没问题，这似乎是正确签名的。

问题是SecurityTokenReference仅在调用ComputeSignature（）时创建，因此我无法向此元素添加签名引用，因为它在需要时不存在（在重写在ComputeSignature（）之前调用的SignedXml的GetIdElement方法

我用来创建要插入Security头的签名块的代码如下：

   string certificatePath = System.Windows.Forms.Application.StartupPath + "\\" + "Certs\\sign-and-    enc.p12";

    XmlDocument xd = new XmlDocument();
    xd.LoadXml(xml);

    // Set Certificate 
    System.Security.Cryptography.X509Certificates.X509Certificate2 cert = new X509Certificate2(certificatePath, "password");
    MySignedXml signedXml = new MySignedXml(xd);
    signedXml.SigningKey = cert.PrivateKey;

    // Create a new KeyInfo object. 
    KeyInfo keyInfo = new KeyInfo();
    keyInfo.Id = "";

    MemoryStream keyInfoStream = new MemoryStream();
    XmlWriter keyInfoWriter = XmlWriter.Create(keyInfoStream);

    WSSecurityTokenSerializer.DefaultInstance.WriteKeyIdentifierClause(keyInfoWriter, new LocalIdKeyIdentifierClause("token_reference", typeof(X509SecurityToken)));   

    keyInfoWriter.Flush();
    keyInfoStream.Position = 0;
    XmlDocument keyInfoDocument = new XmlDocument();
    keyInfoDocument.Load(keyInfoStream);

    XmlAttribute attrib = keyInfoDocument.CreateAttribute("ValueType");
    attrib.InnerText = "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-x509-token-profile-1.0#X509v3";
    keyInfoDocument.ChildNodes[1].ChildNodes[0].Attributes.Append(attrib);

    KeyInfoNode keyInfoNode = new KeyInfoNode();
    keyInfoNode.LoadXml(keyInfoDocument.DocumentElement);
    keyInfo.AddClause(keyInfoNode);

    // Add the KeyInfo object to the SignedXml object. 
    signedXml.KeyInfo = keyInfo;

    // Need to use External Canonicalization method. 
    signedXml.SignedInfo.CanonicalizationMethod = "http://www.w3.org/2001/10/xml-exc-c14n#";

    // Create a reference to be signed. 
    Reference reference = new Reference();
    reference.Uri = "#UsernameToken-1";

    XmlDsigEnvelopedSignatureTransform env = new XmlDsigEnvelopedSignatureTransform();
    env.Algorithm = "http://www.w3.org/2001/10/xml-exc-c14n#";
    reference.AddTransform(env);
    reference.DigestMethod = "http://www.w3.org/2000/09/xmldsig#sha1";
    signedXml.AddReference(reference);


    Reference reference2 = new Reference();
    reference2.Uri = "#token_reference";
    XmlDsigEnvelopedSignatureTransform env2 = new XmlDsigEnvelopedSignatureTransform();
    env2.Algorithm = "http://www.w3.org/2001/10/xml-exc-c14n#";
    reference2.AddTransform(env2);
    reference2.DigestMethod = "http://www.w3.org/2000/09/xmldsig#sha1";
    signedXml.AddReference(reference2);

    // Add the Signature Id 
    signedXml.Signature.Id = "MYSIG_ID";

    // Compute the signature. 
    signedXml.ComputeSignature();

    XmlElement xmlDigitalSignature = signedXml.GetXml();

其中xml变量是UsernameToken xml字符串，MySignedXml类是一个子类化的SignedXml，其中覆盖了GetIdElement方法（试图找到并正确地重新排列不存在的SecurityTokenReference）

我现在花费数天时间研究和测试，不幸的是，提供服务的公司没有任何帮助 - 但我需要使用他们的服务。

最后整理了今天的问题。在术语方面，我需要签署的不是SecurityTokenReference，而是二进制安全令牌。

为了做到这一点，我需要隐藏Initiator和Recipient的证书，并添加一个签名的支持令牌。

我回去使用配置来创建和签名消息，而不是尝试手动添加签名。

其他可能阻止其工作的问题是我的自定义“Messaging”标题上有一个不正确的命名空间，所以要注意命名空间，我不认为它们会像它们那样重要。

创建绑定的代码如下

    private System.ServiceModel.Channels.Binding GetCustomBinding()
    {
        System.ServiceModel.Channels.AsymmetricSecurityBindingElement asbe = new AsymmetricSecurityBindingElement();
        asbe.MessageSecurityVersion = MessageSecurityVersion.WSSecurity11WSTrust13WSSecureConversation13WSSecurityPolicy12;

        asbe.InitiatorTokenParameters = new System.ServiceModel.Security.Tokens.X509SecurityTokenParameters { InclusionMode = SecurityTokenInclusionMode.Never };
        asbe.RecipientTokenParameters = new System.ServiceModel.Security.Tokens.X509SecurityTokenParameters { InclusionMode = SecurityTokenInclusionMode.Never };
        asbe.MessageProtectionOrder = System.ServiceModel.Security.MessageProtectionOrder.SignBeforeEncrypt;

        asbe.SecurityHeaderLayout = SecurityHeaderLayout.Strict;
        asbe.EnableUnsecuredResponse = true;
        asbe.IncludeTimestamp = false;
        asbe.SetKeyDerivation(false);
        asbe.DefaultAlgorithmSuite = System.ServiceModel.Security.SecurityAlgorithmSuite.Basic128Rsa15;
        asbe.EndpointSupportingTokenParameters.Signed.Add(new UserNameSecurityTokenParameters());
        asbe.EndpointSupportingTokenParameters.Signed.Add(new X509SecurityTokenParameters());

        CustomBinding myBinding = new CustomBinding();
        myBinding.Elements.Add(asbe);
        myBinding.Elements.Add(new TextMessageEncodingBindingElement(MessageVersion.Soap11, Encoding.UTF8));

        HttpsTransportBindingElement httpsBindingElement = new HttpsTransportBindingElement();
        httpsBindingElement.RequireClientCertificate = true;
        myBinding.Elements.Add(httpsBindingElement);

        return myBinding;
    }

使用绑定时，我设置了ClientCredentials UserName，ServiceCertificate和ClientCertificate，并且所有工作都按预期工作。

使用代码如下

using (CredentialingService.SOAPPortTypeClient client = GetCredentialingClient())
{
    client.Open();
    etc....
}

private static CredentialingService.SOAPPortTypeClient GetCredentialingClient()
{
    CredentialingService.SOAPPortTypeClient client = new CredentialingService.SOAPPortTypeClient(GetCustomBinding(), new EndpointAddress(new Uri(Settings.AppSettings.B2BUrl), new DnsEndpointIdentity(Settings.AppSettings.B2BDNSEndpoint), new AddressHeaderCollection()));
    client.Endpoint.Contract.ProtectionLevel = System.Net.Security.ProtectionLevel.None;
    SetClientCredentialsSecurity(client.ClientCredentials);

    return client;
}

在我的帖子中指定了GetCustomBinding

SetClientCredentialsSecurity是证书的设置位置，如下所示

private static void SetClientCredentialsSecurity(ClientCredentials clientCredentials)
{
    clientCredentials.UserName.UserName = Settings.AppSettings.B2BUserName;
    clientCredentials.UserName.Password = Settings.AppSettings.B2BPassword;

    string directoryName = Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location);
    clientCredentials.ServiceCertificate.DefaultCertificate = new X509Certificate2(Path.Combine(directoryName, Settings.AppSettings.B2BServerCertificateName));
    clientCredentials.ClientCertificate.Certificate = new X509Certificate2(Path.Combine(directoryName, Settings.AppSettings.B2BClientCertificateName), Settings.AppSettings.B2BClientCertificatePassword);
}

希望这会让它更清晰

答案 1 :(得分：0)

也许是因为您的证书不是公开有效的。试试这个：

System.Net.ServicePointManager.ServerCertificateValidationCallback = new System.Net.Security.RemoteCertificateValidationCallback(delegate { return true; });
//...
using (var client = new SrvClient())
{
    client.ClientCredentials.UserName.UserName = "usr";
    client.ClientCredentials.UserName.Password = "psw";
    //...
}
