I laughed so much at that. Encryption is literally just long complicated numbers combined with other long complicated numbers using mathematical formulae. You can’t ban maths.

Now laugh at banning chemistry and physics (guns and explosives and narcotics). Take a laugh at banning murder too - how do you ban every action leading to someone's death?

and the company must not tell anyone about it

Any "must not tell" law is crap. Unless you signed some NDA knowing full well what it is about.

Any kind of "national secret disclosure" punishment when you didn't sign anything to get that national secret is the same.

It's an order given to a free person, not a voluntarily taken obligation.

That said, you can't fight force with words.
