Hey Everyone. I'm using the example sketch from Mysensors MQTT Gateway and node.
I've added the standard RFM69HW items and the node sends data to the gateway.

It would be nice to use signing/encryption so looking through the forums I found:

#define MY_SECURITY_SIMPLE_PASSWD "123456789"
#define MY_SIGNING_SOFT_RANDOMSEED_PIN A0

Using A0 since it is the only analogue pin I have on the Wemos D1 mini.

I pasted the same string to both the node and the gw and while I see they are trying to communicate but get SIGN FAIL.

So I would like to ask if someone has seen a tutorial or knows what needs to be enable for encryption?

@anticimex according to the documentation

MY_SECURITY_SIMPLE_PASSWD Enables security (signing and encryption) without the need for personalization

So the connection should be encrypted and signed without anything else (other than putting the same define statement on all nodes with the same password).
