fix: don't broadcast public keys if the user is licensed

[andrekir]

prevents NodeInfo broadcasts with public keys when the user is licensed.

Do we need this, with the is_licensed change I pushed earlier?

Please excuse my ignorance, but I'm curious to learn why this is necessary. I understand ham has to operate unencrypted, so the licensed node can't send anything encrypted, but why prevent another non-licensed node from sending something encrypted. Must a licensed node also not receive anything encrypted?

Not sure your change will have an effect if they already have keys generated.

yes. public keys are still being sent in the NodeInfo broadcasts when is_licensed is true.

Last time I checked, I came to the conclusion that it was a problem, yes. Of course I can't currently find that source.

Got it. Yeah, looks good then.

I tried to find the legislative answer to amateur radio and encryption and only went down a rabbit hole. In Australia atleast from https://www.acma.gov.au/amateur-radio-operating-procedures I found the following.

But receiving signals as an amateur would mean the other party could only be another amateur and thus only unencrypted anyway. This not allowing reception of unencrypted would just be additional checks and balances.

Except

Encryption/scrambling
Transmissions from an amateur station must not be encrypted or scrambled, except for signals used to control a satellite, signals used to control a remote amateur station or by stations participating in emergency services operations or exercises.

Re-transmission
If you re-transmit another station’s transmission, you must have the other station’s permission and indicate it is a retransmission.
