-The origins of computer science are in cryptography, or the study of encryption and decryption.
During WW2, codebreakers used some of the first practical computers built off of the Von Neumman architecture.
It helped shorten the war by a number of projected years, and kick started the Age of Information & Computing.
Cryptography remains an important facet of Computer Science today, seeing extensive use in cybersecurity
to keep private and important data safe from bad actors. Random numbers are used in this aspect generated from
hash functions to make keys so astronomically unlikely to be able to guess such that some systems simply cannot be
broken into via brute force in any reasonable amount of time.
