generating ssl certicifacate for windows 8.1

I used the following site to generate an SSL key.

http://www.mobilefish.com/services/ssl_certificates/ssl_certificates.php#ssl_certificates_output

However when I am starting Express I am getting this error.

> rest-server@0.0.0 start 
C:\Users\Theodosios\Desktop\NodeJs_Coursera\Node_Js\re
st-server-passport
> node ./bin/www

_tls_common.js:69
  c.context.setCert(options.cert);

And this is the www file inside the bin folder.

            #!/usr/bin/env node

        var http = require('http');
        var https = require('https');
        var fs = require('fs');

        /**

         */

        var port = normalizePort(process.env.PORT || '3000');

        app.set('port', port);
        app.set('secPort', port + 443);

        /**

        var server = http.createServer(app);

        /**

        server.listen(port, function () {
            console.log('Server listening on port ', port);
        });
        server.on('error', onError);
        server.on('listening', onListening);

        /**

        var secureServer = https.createServer(options, app);

         */

        secureServer.listen(app.get('secPort'), function () {
            console.log('Server listening on port ', app.get('secPort'));
        });
        secureServer.on('error', onError);
        secureServer.on('listening', onListening);

        /**

                return val;
            }
            if (port >= 0) {
                // port number
                return port;
            }
            return false;
        }

        /**

        function onError(error) {
            if (error.syscall !== 'listen') {
                throw error;
            }
            var bind = typeof port === 'string'
                ? 'Pipe ' + port

            // handle specific listen errors with friendly messages
            switch (error.code) {
                case 'EACCES':
                    console.error(bind + ' requires elevated privileges');
                    process.exit(1);
                    break;

                    process.exit(1);
                    break;

                default:

            }
        }

        /**

         */

        function onListening() {
            var addr = server.address();
            var bind = typeof addr === 'string'

                : 'port ' + addr.port;
            debug('Listening on ' + bind);
        }

Any ideas how to fix this problem?

Thanks,

Theo.
