test.mosquitto.org Certificate ..

i did a simple test (which work with MQTTnet but do not work with emitter - can you make it working)
--------------- code ----------------------

using System;
using System.Text;
using System.Threading;

using Emitter;
using Emitter.Messages;

using System.Security.Cryptography.X509Certificates;

namespace EmitterMQTTMossquitto

    class Program
    {
        static void Main(string[] args)
        {
            MqttClient client = null;
            string clientId;
 
            X509Certificate caCert = new X509Certificate(Encoding.UTF8.GetBytes(GetCertificate));
   
            // connect to the Mosquito test server
            client = new MqttClient("test.mosquitto.org", 8883, true, caCert, null, MqttSslProtocols.TLSv1_2);

            // use a unique id as client id, each time we start the application
            clientId = Guid.NewGuid().ToString();

            Console.WriteLine("Connecting to Mosquito test server...");

            client.Connect(clientId);

            Console.WriteLine("Connected to Mosquito test server");

            while (true)
            {
                // send random temperature value to Gauge demo in Mosquito test server, see http://test.mosquitto.org/gauge/
                client.Publish("temp/random", GetRandomTemperature(), MqttMsgBase.QOS_LEVEL_EXACTLY_ONCE, false);

                // the Mosquito test server has a local process that updates every 15 seconds, so we just follow that
                Thread.Sleep(15000);
            }

        }

        private static byte[] GetRandomTemperature()
        {
            // generate random value
            Random randomProvider = new Random();
            var randomTemperature = randomProvider.NextDouble() * 10;

            // convert to string formatted NN.NN
            var temperatureAsString = randomTemperature.ToString("N2");

            Console.WriteLine($"Temperature: {temperatureAsString}");

            return Encoding.UTF8.GetBytes(temperatureAsString);
        }

        // Mosquito test server CA certificate
