: If it's encryption you're after, these gadgets are a very nice way
: to generate a one-time pad, which is not breakable even in theory.
: (You still have to worry about someone Xeroxing your one-time pad, or
: intercepting its transmission to users, but that's a whole different

	really?

	seems reasonable that top
	hardware randomization is
	preferable in all applications
	where a stream of unpredictable
	(i.e. unbreakable) randoms is
	wanted...
	tactical applications would seem
	to fit this,
	yes?
