- An enormous amount has been done on this subject by the cryptological
- fraternity. In fact, most cryptosystems in use outside the banking world
- seem to work by applying a pseudo-random number stream to the plaintext.

- Suggestion: if you want a really good random number generator for stats
- work, just encrypt a counter using the DES algorithm. If you can find
- anything statistically wrong with this, then you'll be famous (if the
- spooks don't get to you first).
