/* This module is part of the cryptlib continuously seeded pseudorandom
   number generator.  For usage conditions, see random.c.

   This code represents a template for randomness-gathering only and will
   need to be modified to provide randomness via an FPGA hardware entropy
   source such as a standard ring oscillator generator.  In its current
   form it does not provide any usable entropy and should not be used as an
   entropy source */
