Question

我需要使用WS Security将我的.NET Framework 4客户端应用程序连接到部署在Apache CXF上的Web服务。那项服务不受我的控制。

该服务作为“服务参考”添加到项目中。

这是代理：

ServicePointManager.ServerCertificateValidationCallback = New System.Net.Security.RemoteCertificateValidationCallback(AddressOf AcceptAllCertifications) 

Dim oBinding As New CustomBinding()
Dim oSecurity As SecurityBindingElement

oSecurity = AsymmetricSecurityBindingElement.CreateCertificateOverTransportBindingElement(MessageSecurityVersion.WSSecurity11WSTrust13WSSecureConversation13WSSecurityPolicy12BasicSecurityProfile10)
oSecurity.IncludeTimestamp = True

oBinding.Elements.Add(oSecurity)
oBinding.Elements.Add(New CertFixEscapedComma.CertRefEncodingBindingElement())
   ( This a custom message encoder)
CertFixEscapedComma.CertRefEncoder.CERTIFICADO = Convert.ToBase64String(oCertificado.RawData) 

oBinding.CloseTimeout = New TimeSpan(0, 2, 0)

Dim oTransport As New HttpsTransportBindingElement()
oBinding.Elements.Add(oTransport)

Dim oProxyClient As New NameServiceClient(oBinding, New System.ServiceModel.EndpointAddress(New Uri("https://url_service")))
Dim oCertificado As X509Certificate2
oCertificado = function_client_certificate() ' this get the proper cert


oProxyClient.ClientCredentials.ClientCertificate.Certificate = oCertificado
oProxyClient.name_function(params) 'call to the remote service

好。服务器接受我的请求，并以这种方式发送响应：

我收到错误“无法解析KeyInfo以解包密钥”。阅读有关那种肥皂信息的OASIS文档，我认为这个信息没问题。

我尝试使用自定义编码器更改“X509IssuerSerial”节点，以获得“。相同错误。

我可以直接阅读邮件，使用证书执行手动密钥解密。然后，使用密钥，我可以解密数据。所以数据是正确的。

但是，我不是这样的。我想使用服务参考。

通过NET代码，我看到堆栈跟踪：

因此，在“System.ServiceModel.Security.WSSecurityJan2004.WrappedKeyTokenEntry.ReadTokenCore”中，它正在尝试“CreateWrappedKeyToken”，并在此抛出异常：

   WrappedKeySecurityToken CreateWrappedKeyToken(string id, string encryptionMethod, string carriedKeyName,
                SecurityKeyIdentifier unwrappingTokenIdentifier, byte[] wrappedKey, SecurityTokenResolver tokenResolver)
            {
                ISspiNegotiationInfo sspiResolver = tokenResolver as ISspiNegotiationInfo;
                if (sspiResolver != null)
                {
                    ISspiNegotiation unwrappingSspiContext = sspiResolver.SspiNegotiation;
                    // ensure that the encryption algorithm is compatible
                    if (encryptionMethod != unwrappingSspiContext.KeyEncryptionAlgorithm)
                    {
                        throw DiagnosticUtility.ExceptionUtility.ThrowHelperError(new MessageSecurityException(SR.GetString(SR.BadKeyEncryptionAlgorithm, encryptionMethod)));
                    }
                    byte[] unwrappedKey = unwrappingSspiContext.Decrypt(wrappedKey);
                    return new WrappedKeySecurityToken(id, unwrappedKey, encryptionMethod, unwrappingSspiContext, unwrappedKey);
                }
                else
                {
                    if (tokenResolver == null)
                    {
                        throw DiagnosticUtility.ExceptionUtility.ThrowHelperError(new ArgumentNullException("tokenResolver"));
                    }
                    if (unwrappingTokenIdentifier == null || unwrappingTokenIdentifier.Count == 0)
                    {
                        throw DiagnosticUtility.ExceptionUtility.ThrowHelperError(new MessageSecurityException(SR.GetString(SR.MissingKeyInfoInEncryptedKey)));
                    }

                    SecurityToken unwrappingToken;
                    SecurityHeaderTokenResolver resolver = tokenResolver as SecurityHeaderTokenResolver;
                    if (resolver != null)
                    {

unwrappingToken = resolver.ExpectedWrapper; if（unwrappingToken！= null）

                        {
                            if (!resolver.CheckExternalWrapperMatch(unwrappingTokenIdentifier))
                            {
                                throw DiagnosticUtility.ExceptionUtility.ThrowHelperError(new MessageSecurityException(
                                    SR.GetString(SR.EncryptedKeyWasNotEncryptedWithTheRequiredEncryptingToken, unwrappingToken)));
                            }
                        }
                        else
                        {
                            throw DiagnosticUtility.ExceptionUtility.ThrowHelperError(new MessageSecurityException(
                                SR.GetString(SR.UnableToResolveKeyInfoForUnwrappingToken, unwrappingTokenIdentifier, resolver)));
                        }
                    }

...

所以，在“unwrappingToken = resolver.ExpectedWrapper”中，我得到一个“null”。

这可能是某种“消息名称空间不匹配”，或类似的东西，我看不到？

证明它没问题且有效。它具有所有x509v3属性，发行者是受信任的发行者...

帮助我们，我的屈光度正在增加......

Answer 1

我认为肥皂消息是错误的。 wsse:Reference元素包含不存在的URI：URI =＆＃34;＃EK-4A5A4F8820EFD673E7152328322340610394＆＃34;。通常，此URI应引用wsse:BinarySecurityToken元素，其wsu:Id值与此URI对应。你的肥皂反应中似乎没有这个。

wsse:BinarySecurityToken元素包含x509证书，或者在您的情况下包含对它的引用。由于无法解析URI，因此您的客户端无法确定要使用的x509证书。

Answer 2

好吧，终于我可以摆脱这条消息了。您需要确保服务是否使用相同的证书进行身份验证和加密。例如，您可以使用提琴手来获取公钥的证书。

如果答案为“否”，则需要自定义客户端凭据，如下所示：

Public Class MyClientCredentials
  Inherits ClientCredentials


Public Sub New()

End Sub 

' Perform client credentials initialization.    
Protected Sub New(ByVal other As MyClientCredentials)
    MyBase.New(other)
End Sub

''' <summary>
''' Link to token manager
''' </summary>
''' <returns></returns>
Public Overrides Function CreateSecurityTokenManager() As SecurityTokenManager
    ' Return your implementation of the SecurityTokenManager.
    Return New MyClientCredentialsSecurityTokenManager(Me)

End Function

自定义令牌管理器正在执行以下操作：

Public Class MyClientCredentialsSecurityTokenManager
  Inherits ClientCredentialsSecurityTokenManager
Private _oCredenciales As MyClientCredentials

Public Sub New(ByVal credentials As MyClientCredentials)
    MyBase.New(credentials)
    Me._oCredenciales = credentials

End Sub

''' <summary>
''' Custom token for each operation
''' </summary>
''' <param name="p_oRequirement"></param>
''' <returns></returns>
Public Overrides Function CreateSecurityTokenProvider(ByVal p_oRequirement As SecurityTokenRequirement) As SecurityTokenProvider

    Dim oRes As SecurityTokenProvider = Nothing
    If p_oRequirement.TokenType = SecurityTokenTypes.X509Certificate Then
        Dim direction = p_oRequirement.GetProperty(Of MessageDirection)(ServiceModelSecurityTokenRequirement.MessageDirectionProperty)
        If direction = MessageDirection.Output Then
            If p_oRequirement.KeyUsage = SecurityKeyUsage.Signature Then
                oRes = New X509SecurityTokenProvider(Me._oCredenciales.ClientCertificate.Certificate)
            Else
                oRes = New X509SecurityTokenProvider(Me._oCredenciales.ServiceCertificate.DefaultCertificate())
            End If
        End If
    Else
        oRes = MyBase.CreateSecurityTokenProvider(p_oRequirement)
    End If

    Return oRes

End Function

现在，将其应用于频道：

oServicio.ChannelFactory.Endpoint.Behaviors.Remove(Of ClientCredentials)()
oServicio.ChannelFactory.Endpoint.Behaviors.Add(oCred)

我希望这会对将来的人有所帮助。
