Cryptography for the Everyday Developer: Encryption Basics with Classical Ciphers
This is the first article in a series on Cryptography for the Everyday Developer. Follow along to learn the basics of modern cryptography and encryption. The best way to begin learning about encryption is by example. And thankfully, there exist many examples of encryption throughout history that we can draw from. One of the earliest well-known examples of encryption is the Caesar Cipher, and we will begin there. The Caesar cipher is one of the oldest and simplest forms of encryption. It works by shifting each letter in your message a fixed number of positions down the alphabet. For example, with a shift of 3: ...
