The DMCA is of particular interest because it's a potential counterexample of your assertion that other tools or intent are necessary to make distribution of a number illegal. The whole point is that it's a bad law, primarily because it's unclear what it prevents you from doing.
The law is pretty clear, though, on stabbing people and committing espionage.
Where in the law does it say that you aren't allowed to stab someone with a screw driver? Nowhere. That doesn't mean it isn't strictly implied.
Secondly, the DMCA isn't of particular interest here: the number might as well constitute a secret pertaining to national security, distribution of which may get you the death penalty for espionage.
