NSA can. Easily.
The NSA can break 256bit encryption easily? You might want to let them know as I’m sure they will be very interested. Unless of course your definition of easy is to fire up your handy super computer and let it run for a billion years or so.
Uh. No. I know some of the people who supply the NSA supercomputers and the answer is still, no.
You want to break the laws of math. . . and think that government bureaucrats can do better than what can be done in research labs. BS! You’ve been watching too many movies.
