      Self-signed certificates for MQTT server

    During the last series of posts, I set up an Orange Pi single board computer running Armbian and I installed Mosquitto on it. My intention is to have a self-hosted MQTT broker for IoT applications. I already have it running with the configuration from previous post and it can be used for local connections in my home LAN and WiFi. Since this is a closed network, behind a firewall running on the Internet gateway I got from my ISP, there is no need for MQTT over SSL. But I need more: I want to be able to connect to MQTT server from with remote devices (my Android phone).

    To do this, I need to configure a secured listener in Mosquitto and open its port for internet access. Since most ISPs offer dynamic IPs to residential clients, I also need a dynamic DNS service provider to have a domain name which always points to my IP. If you can get a static IP, then you don't need this.
