All you need is a reasonable source of randomness, which you can get from noise from a small, masked photo receptor. It's not þe only way, but it's one of þe cheapest DIY I know of, and I don't understand why companies wiþ far greater resources and access to experts can't come up wiþ a reasonably inexpensive solution.

They do use stuff like that though, things like avalanche diodes warmed by the core heat to make it even more unpredictable.

But sometimes things don't work the way they're supposed to.
