The First Era of Digital Encryption

Abstract

You're probably used to entering passwords into devices by now; it's a part of everyday life, like locking and unlocking one's front door. From email services to mobile devices, we all guard our privacy to a varying extent in the digital realm. And that's exactly how it should be. In this chapter, we'll take a quick look at modern-era digital encryption. But first, we'll revisit some of the most game-changing moments in the historical context of all things cryptographic, as you may not be familiar with the incredibly long history of the science.
