使用dotnet中的ssl进行双向身份验证

Question

我有一个项目,我需要通过Web请求发送数据文件.我们需要设置双向身份验证,也称为相互身份验证.我们不确定是否需要特殊证书,但我们知道它需要达到3级.

我在查找此案例的示例代码时遇到问题.我不知道在哪里添加我们的证书信息.使用此代码Underlying connection is closed时,当我们尝试读取响应流并且ServicePointManager.ServerCertificateValidationCallback从未调用时会抛出错误.这是我有的:

ServicePointManager.ServerCertificateValidationCallback = New Security.RemoteCertificateValidationCallback(AddressOf MyCertValidationCb)
            httpReq = CType(System.Net.HttpWebRequest.Create(url), HttpWebRequest)
            For Each cert As String In certs
                X509cert = X509Certificate2.CreateFromCertFile(cert)
                X509cert2 = New X509Certificate2(X509cert)
                httpReq.ClientCertificates.Add(X509cert2)
            Next
            httpReq.Method = "POST"        ' Post method
            httpReq.ContentType = "text/xml"               ' content type

            ' Wrap the request stream with a text-based writer
            writer = New StreamWriter(httpReq.GetRequestStream())
            ' Write the XML text into the stream
            reader = New StreamReader(filename.Name)
            ret = reader.ReadToEnd()
            reader.Close()
            ' Send the data to the webserver
            writer.WriteLine(ret)
            writer.Close()
            ' Wait for response
            Dim httpRsp As System.Net.HttpWebResponse = CType(httpReq.GetResponse(), HttpWebResponse)
            sr = New StreamReader(httpRsp.GetResponseStream)
            responseText = sr.ReadToEnd

            If httpReq IsNot Nothing Then
                httpReq.GetRequestStream().Close()
            End If
            If httpRsp IsNot Nothing Then
                httpRsp.GetResponseStream().Close()
            End If

任何有示例代码的博客提示或链接都会很棒.谢谢.

您不需要“特殊”证书。您的客户端需要自己的证书，并在连接中使用它来告诉服务器其身份。这称为客户端证书。服务器应该正确处理这个问题。
