hi there,
i wonder if someone has any experience while setting a secret wifi key within the default-configuration without using local public data? (e.g. mac, serial oder similar)
my goal is to generate a config with all relevant paremeters incl. the wifikey, which cannot be recalculated back.
maybe any hidden parameter or similar recommendation how i can do that?
(i wanna print out the key on the backside of the cpe - and of course after an factory-reset it should be work again 
)
thank you for your great help!
