If you use Meshtastic for exchanging messages you don't want other people to see, `random` is the setting you should use. Selecting a `default` or any of the `simple` values from the following table will use publicly known encryption keys. They're shipped with Meshtastic source code and thus, anyone can listen to messages encrypted by them. They're great for testing and public channels.
