It's not at all essentially the same, although you may be correct that
it's good enough. If you find a star that decrypts the message to
something sensible, you can be pretty sure the decryption was correct;
that's not at all true of one-time pads.

The imaginable --- the space of one-time pad keys --- is unimaginably
larger than the universe.
