Whether it’s a game of D&D or encrypting top-secret information, a wide array of methods are available for generating the needed random numbers with high enough entropy for their use case… ...

When you use a machine to generate a “random” number, then, what you’re actually getting is almost certainly a “pseudorandom” number – something that looks random, but technically isn’t.

The random numbers generated are used in most cryptographic algorithms to determine the fundamental security of the entire system that relies on them.
