.net - System.Net.WebRequest 和 TLS 1.2 使用 haproxy 创建一个 'Handshake Failure'

Question

我无法使用 System.Net.WebRequest对于 TLS 1.2 的请求。
如果这样做，我会得到一个异常 The request was aborted: Could not create SSL/TLS secure channel.和协议(protocol)错误Handshake Failure .

通过 TLS 1.2 和身份验证的连接正在使用 Internet Explorer 和 Chrome。
OpenSSL 可以通过 TLS 1.2 连接到此端点。

设置

使用 ClientCertificates 进行身份验证

使用非默认端口

使用 TLS 1.2

端点是一个 haproxy，但这是一个黑盒

.NET 4.7 和 C#

代码片段

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

方法 GetCertificate()返回带有嵌入在此软件中的私钥的证书。

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)

returned code在 TLS 1.2 中是 IllegalMessage在 TLS 1.0 中它是 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"/>

到您的 .config 文件中，您将看到“AcquireCredentialsHandle() 失败，错误为 0X8009030D。”或类似的东西。如果 key 不在 MachineKeys 系统文件夹中，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 key 文件的访问权限等。
