But it is, TO ME.
I'm sure the USA government thinks just as much of their own data, but not even they opt for such drastic measures. AES-128 and above are hard enough that even a super computer couldn't crack them within the lifespan of a human being. Unless you're storing the blueprints for Skynet-level AI, your methods are serious overkill.
