HTTPS: ignore untrusted certificate?

I needed the same thing. In case someone still need it, here is the answer:

  IEnumerator Start () 
 {
     
     ServicePointManager.ServerCertificateValidationCallback = TrustCertificate;
     
     
     HttpWebRequest request = (HttpWebRequest) WebRequest.Create( "https://yoururl.com" );
     HttpWebResponse response = (HttpWebResponse) request.GetResponse();
     
     Stream dataStream = response.GetResponseStream ();
     StreamReader reader = new StreamReader (dataStream);
     string responseFromServer = reader.ReadToEnd ();
     
     Debug.Log ("responseFromServer=" + responseFromServer );
     
     yield return 0;
 }

     //http://stackoverflow.com/questions/3674692/mono-webclient-invalid-ssl-certificates
 private static bool TrustCertificate(object sender, X509Certificate x509Certificate, X509Chain x509Chain, SslPolicyErrors sslPolicyErrors)
 {
     // all Certificates are accepted
     return true;
 }
