c# - 使用客户端证书身份验证连接到 Web 服务

Question

我得到了一个 .p12 文件，用于使用客户端证书身份验证通过 SSL 连接到 Web 服务。我使用 cURL 在 PHP 中成功地工作了。这些是我在执行请求时使用的选项:

$headers = array(
    'Method: POST',
    'Connection: Keep-Alive',
    'User-Agent: PHP-SOAP-CURL',
    'Content-Type: text/xml; charset=utf-8',
    'SOAPAction: "'.$action.'"',
);

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, $location);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $request);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
curl_setopt($ch, CURLOPT_FAILONERROR, 1);
curl_setopt($ch, CURLOPT_SSLCERT, $this->clientcert);
curl_setopt($ch, CURLOPT_SSLKEYTYPE, $this->clientcerttype);
curl_setopt($ch, CURLOPT_SSLKEY, $this->keyfile);
curl_setopt($ch, CURLOPT_SSLKEYPASSWD, $this->keypassword);
curl_setopt($ch, CURLOPT_SSLVERSION, 3);

$response = curl_exec($ch);

我现在正尝试使用 C# 和 .NET 执行相同的任务，但我不断收到错误消息“无法使用权​​限‘:’为 SSL/TLS 建立安全通道。”。

我似乎没有找到 key 的问题，而且似乎没有任何信任问题。尽管如此，还是有些地方不对劲。

我已经制作了一个测试程序，这样我就可以测试一个基本的调用是否有效。

public void StartviaWSHttp()
{
    var binding = new WSHttpBinding();
    binding.Security.Mode = SecurityMode.Transport;
    binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.None;
    binding.Security.Message.NegotiateServiceCredential = false;
    binding.Security.Message.ClientCredentialType = MessageCredentialType.None;

    var baseAddress = new Uri("https://<host>:<port>/LineEndpoint1");
    var endpointAddress = new EndpointAddress(baseAddress);

    var client = new LinePortTypeClient(binding, endpointAddress);

    client.ClientCredentials.ClientCertificate.SetCertificate(StoreLocation.CurrentUser, StoreName.My, X509FindType.FindBySerialNumber, "00d48a233bf4b77523");

    Debug.Assert(client.ClientCredentials.ClientCertificate.Certificate.SerialNumber.ToLower() == "00d48a233bf4b77523");

    var header = new ctSoapHeaderMsg();
    var response = new object();
    client.Open();
    var responseCode = client.PerformFunction(ref header, "0893411111", out response);
    client.Close();

    Console.WriteLine("Response Code :" + responseCode);
    Console.WriteLine("Response :" + response);
}

当我在当前用户的个人/证书中查看证书时，它没有报告任何关于信任的问题。在证书信息中，写明该证书的用途如下:所有的颁发政策和所有的申请政策。证书路径只有一个条目，证书状态报告“此证书正常”。

我不知道问题是什么。可能存在信任问题，因为我为 PHP 调用关闭了 PEER 和 HOST 验证。我不确定这是否是 C# 的一个选项。

更新:(2013 年 8 月 9 日) 我为 System.Net 和 System.Net.Socket 设置了一些详细的跟踪。这是输出的开始。

行 System.Net Information: 0 : [16124] TlsStream#29695768::.ctor(host=dsl-wholesale-testing.iinet.net.au, #certs=0) 建议即使我已将证书附加到 client.ClientCredentials.ClientCertificate，也没有选择任何证书供使用，但我不确定为什么会发生这种情况或如何让它坚持下去。证书的任何属性是否必须与我要连接的主机名相匹配？

看来服务器不理解 TLS。

我必须指定 SSLv3，通过

System.Net.ServicePointManager.SecurityProtocol = System.Net.SecurityProtocolType.Ssl3;
