Security of the IoT-Hub-Node

[itscooljo]

Hi guys,

first of all, I am new to this matter so excuse me for beeing a total noob on this topic. I plan to use Node-RED plus the IoT-Hub Node to send Data to the Azure cloud.

Microsoft says that the IoT-Hub only accepts connections via MQTT over port 8333. Furthermore it is required that the entire connection is encrypted via TLS/SSL.

Obviously the Node works just fine but i was wonderding wether it establishes any secure connection at all?

Thank you for your answers!
