/**
* Get a seed to use in conjunction with random functions.
* Get random data.
*
* This function can be called repeatedly to generate more random bits
* as needed. It is generally quite slow, and usually used to seed a
* PRNG. As it uses /dev/urandom and /dev/random, the quality of the
* returned random data depends on the platform.
