The purpose of this feature is to create the most random number/string possible, and have it work on every system. The API is still undetermined.
This will attempt several methods until eventually finding one that's available to the system. It should always work.
From all systems:
Linux and related friends:
Optionals as per users desire and setup:
Still under review. Probably a simple function (get_random_string()) and/or a more feature rich class.
