Overview:

MQTT Distributor can be enabled to use TLS for encryption of the communication between MQTT clients.  This is useful if MQTT Distributor is used on a public network.  Since MQTT communications are not encrypted by default, enabling TLS is highly recommended on a public network.  There are two ways this can be done.  First is to certificate signed by a publicly trusted certificate authority (CA).  While there are nominal costs associated with this, it is the proper and recommended way to go if communicating over the Internet.  Alternatively, it is possible to create and use a self-signed certificate.  This is useful for debugging and development.  However, it is not recommended in production scenarios over the Internet.  It is, however, a viable option if utilizing a private network in which encryption is a requirement.
