The hw_random framework is software that makes use of a
special hardware feature on your CPU or motherboard,
a Random Number Generator (RNG). The software has two parts:
- a core providing the /dev/hw_random character device and its

CLASS DEVICE. There is a /sys/class/misc/hw_random node with
two unique attributes, "rng_available" and "rng_current". The
