System.Net.WebRequest和TLS 1.2使用haproxy创建"握手失败"

Question

我无法使用System.Net.WebRequestTLS 1.2的请求.如果我这样做,我会收到异常The request was aborted: Could not create SSL/TLS secure channel.和协议错误Handshake Failure.

通过TLS 1.2连接和身份验证可与Internet Explorer和Chrome配合使用.OpenSSL可以通过TLS 1.2连接到这个端点.

建立

1. 使用ClientCertificates进行身份验证
2. 使用非默认端口
3. 使用TLS 1.2
4. 端点是haproxy,但这是一个黑盒子
5. .NET 4.7和C#

代码snipplet

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
var req = WebRequest.Create($"https://{host}:{port}");
((HttpWebRequest)req).ClientCertificates = new X509Certificate2Collection(GetCertificate());
var requestStream = req.GetRequestStream();

该方法GetCertificate()返回带有私钥的证书,该私钥嵌入在该软件中.

更新

感谢@ user3484348我现在有更多信息.

TLS 1.2(不工作):

System.Net Information: 0 : [11752] InitializeSecurityContext(
credential = System.Net.SafeFreeCredential_SECURITY, 
context = 1054ea8:6091710, 
targetName = api.company.com, 
inFlags = ReplayDetect, SequenceDetect, Confidentiality, AllocateMemory, InitManualCredValidation)

System.Net Information: 0 : [11752] InitializeSecurityContext(
In-Buffers count=2, 
Out-Buffer length=0, 
returned code=IllegalMessage)

TLS 1.0(工作):

System.Net Information: 0 : [11752] InitializeSecurityContext(
credential = System.Net.SafeFreeCredential_SECURITY, 
context = 12a5eb0:641d900, 
targetName = api.company.com, 
inFlags = ReplayDetect, SequenceDetect, Confidentiality, AllocateMemory, InitManualCredValidation)

System.Net Information: 0 : [11752] InitializeSecurityContext(
In-Buffers count=2, 
Out-Buffer length=0, 
returned code=ContinueNeeded)

将returned code在TLS 1.2 IllegalMessage和TLS 1.0它ContinueNeeded.

您的 GetCertificate() 可能返回的证书不是来自 Windows 证书存储库。如果您通过添加来打开应用程序的 System.Net 调试信息

  <system.diagnostics>
<sources>
  <source name="System.Net">
    <listeners>
      <add name="System.Net"/>
    </listeners>
  </source>
  <source name="System.Net.Cache">
    <listeners>
      <add name="System.Net"/>
    </listeners>
  </source>
  <source name="System.Net.Http">
    <listeners>
      <add name="System.Net"/>
    </listeners>
  </source>
  <source name="System.Net.Sockets">
    <listeners>
      <add name="System.Net"/>
    </listeners>
  </source>
  <source name="System.Net.WebSockets">
    <listeners>
      <add name="System.Net"/>
    </listeners>
  </source>
</sources>
<switches>
  <add name="System.Net" value="Verbose"/>
  <add name="System.Net.Cache" value="Verbose"/>
  <add name="System.Net.Http" value="Verbose"/>
  <add name="System.Net.Sockets" value="Verbose"/>
  <add name="System.Net.WebSockets" value="Verbose"/>
</switches>
<sharedListeners>
  <add name="System.Net"
    type="System.Diagnostics.TextWriterTraceListener"
    initializeData="network.log"
  />
</sharedListeners>
<trace autoflush="true"/>

在您的 .config 文件中，您将看到“AcquireCredentialsHandle() 失败，错误为 0X8009030D”。或类似的东西。如果私钥不在 MachineKeys 系统文件夹中，则 System.Net 似乎无法使用带有私钥的证书。

走传统路线——将证书添加到存储库、授予对密钥文件的访问权限等。
