Module x86::random

Instructions to generate random bits directly from the hardware (RDRAND and RDSEED).

The decision process for which instruction to use is based on what the output will be used for. If you wish to seed another pseudorandom number generator (PRNG), use RDSEED. For all other purposes, use RDRAND
