Mostly the maths just enables easy key distribution and makes encryption viable for commerce and privacy. I don't see the public benefit in restricting this. It seems more targeted at ordinary citizens than criminals or foreign powers. If all you want to do is bring down the government then you can distribute one time pads on microsd cards and there is not much legislation can do to stop that. Any governments planning to ban xor?
