AUTH packet support for custom authentication


Does HiveMQ support AUTH packet introduced in MQTT 5 ? I am planning to use a custom authentication mechanism: MQTT servers sends a nonce, client sends it back signed using RSA, server verifies the signature. I can’t use normal CONNECT here, because there is no way to send nonce to the client.
I could also use timestamp instead of nonce (then CONNECT is good enough), but this would fail in case of clock desynchronisation.

Hi Jakub,

thank you for your patience.

We plan to introduce an authenticator in the extension system which allows to implement arbitrary authentication mechanisms that require challenge/response AUTH packet flows. Currently there is no timeline when this will be available.
