SSL server

Hi!

I am using Fez Cobra.

I am trying to setup WWW server working with SSL support.

My code is:


HttpListener listener = new HttpListener("https");
byte[] bCert = Resource.GetBytes(Resource.BinaryResources.cert);
X509Certificate cert =  new X509Certificate(bCert);
listener.HttpsCert = cert;
listener.Start();

HttpListenerContext ctx;
while (true)
{
ctx = listener.GetContext();
try
{
new RequestProcess(ctx);
}
catch (Exception ex)
{
Debug.Print(ex.Message);
}
}

But it does not work. I’ve got exception:


 #### Exception System.NotSupportedException - CLR_E_NOT_SUPPORTED (6) ####
    #### Message: 
    #### Microsoft.SPOT.Net.Security.SslNative::SecureServerInit [IP: 0000] ####
    #### Microsoft.SPOT.Net.Security.SslStream::Authenticate [IP: 0037] ####
    #### Microsoft.SPOT.Net.Security.SslStream::AuthenticateAsServer [IP: 000d] ####
    #### Microsoft.SPOT.Net.Security.SslStream::AuthenticateAsServer [IP: 000a] ####
    #### System.Net.HttpListener::AcceptThreadFunc [IP: 0072] ####
A first chance exception of type 'System.NotSupportedException' occurred in Microsoft.SPOT.Net.Security.dll
A first chance exception of type 'System.NotSupportedException' occurred in System.Net.Security.dll
An unhandled exception of type 'System.NotSupportedException' occurred in System.Net.Security.dll

Http works great.
So what is wrong?

Regards,

Jacek

SSL is available on Cobra (EMX) so I am not sure why.

Have you tried the Microsoft examples found in “my documents” folder?

Hi!

I have tried and it is the same exception.

Can You help me?

Did you update the seed in MFDeploy?

Hi !

It works now. Thanks for help. It would be better if this information was included in readme.txt for this sample.

But I have made tests and SSL communication is very slow:
https://device.microsoft.com/ loads in 5.5 sec
http://device.microsoft.com/ loads in 0.25 sec

Why is it so slow?

HTTPS is a heavy protocol and the encryption does impose impacts.
