Classic Cryptography - Substitution Ciphers - Part 2

A few years ago I created a set of presentations for a group of high school students on the fundamentals of classical cryptology. I decided to turn them into videos in the event someone else might find them useful. This video is the second of three presentations that walk through the basics of substitution ciphers and how they work. Today's video will explore how to implement a simple substitution cipher using the Java language. Music Credits The Tower of Light - Stuck in the Air (https://www.youtube.com/watch?v=VCfXtFy7Bhg)
