@lupyuen why do the keys need to be in magic spooky hardware space

@icedquinn Yeah sigh 🙄

@lupyuen i talked about this once with someone who asked me about making secure phones for some hypothetical underground.

i shrugged like "you know there's nothing special about the military stuff right? you can make frequency hopping systems out of any computer controlled radio "

@lupyuen -- How about not storing Security Keys on a public facing server?
