// This implements a cryptographically secure pseudorandom number
// generator for implementing secure demos. The approach taken is to
// use the AES (Rijndael) stream cipher in "counter" mode, encrypting
// an incrementing counter. The cipher key acts as the random seed.
// Cryptanalysis of AES used in this way has shown it to be an
// effective PRNG (see: Empirical Evidence concerning AES, Hellekalek
// & Wegenkittl, 2003).
//
// The AES implementation is from GnuPG. Original copyright notice is
