Essentially they are interested in everyone trying to hide anything from them and they probably understand people of real danger to them will do their best to look ordinary and mediocre. > If their policy says nothing over 256, then they likely have capability for more. Sounds reasonable but breaking 512 obviously is much harder than 256 and will take significant time and resources they don't really want to waste. They will rather force you to reveal the key and only break 512+ if they can't easily reach you physically or identify you in the first place.
