corollary: very very often, cryptography is the place where things go down to a single layer (If you have to hand out some data to a third party, they can do what they want with it, except the mathematically impossible).
Which is fine, math is powerful, but it's only as secure as your key management. Add as many layers as you can to your key management. And then add some more.
