Accessing a web service and a HTTP interface using certificate authentication
- by ADC
It is the first time I have to use certificate authentication.
A commercial partner expose two services, a XML Web Service and a HTTP service. I have to access both of them with .NET clients.
What I have tried
0. Setting up the environment
I have installed the SSLCACertificates (on root and two intermediate) and the client certificate in my local machine (win 7 professional) using certmgr.exe.
1. For the web service
I have the client certificate (der).
The service will be consumed via a .NET proxy.
Here's the code:
OrderWSService proxy = new OrderWSService();
string CertFile = "ClientCert_DER.cer";
proxy.ClientCertificates.Add(new System.Security.Cryptography.X509Certificates.X509Certificate(CertFile));
orderTrackingTO ot = new orderTrackingTO() { order_id = "80", tracking_id = "82", status = stateOrderType.IN_PREPARATION };
resultResponseTO res = proxy.insertOrderTracking(ot);
Exception reported at last statement: The request failed with an empty response.
2. For the HTTP interface
it is a HTTPS interface I have to call through POST method.
The HTTPS request will be send from a .NET client using HTTPWebRequest.
Here's the code:
string PostData = "MyPostData";
//setting the request
HttpWebRequest req;
req = (HttpWebRequest)HttpWebRequest.Create(url);
req.UserAgent = "MyUserAgent";
req.Method = "POST";
req.ContentType = "application/x-www-form-urlencoded";
req.ClientCertificates.Add(new System.Security.Cryptography.X509Certificates.X509Certificate(CertFile, "MyPassword"));
//setting the request content
byte[] byteArray = Encoding.UTF8.GetBytes(PostData);
Stream dataStream = req.GetRequestStream();
dataStream.Write(byteArray, 0, byteArray.Length);
dataStream.Close();
//obtaining the response
WebResponse res = req.GetResponse();
r = new StreamReader(res.GetResponseStream());
Exception reported at last statement: The request was aborted: Could not create SSL/TLS secure channel.
3. Last try: using the browser
In Chrome, after installing the certificates, if I try to access both urls I get a 107 error:
Error 107 (net::ERR_SSL_PROTOCOL_ERROR)
I am stuck.
