Day 1: Introduction to Cryptography Basics and Python

How Does Cryptography Work?

A cipher is like a secret code used to hide messages. It’s made up of a bunch of math stuff that scrambles the message so no one else can read it. You need a special key, like a password, to both scramble and unscramble the message. Using different keys or methods makes the code different every time, like using different keys to lock your door. How safe the message is depends on how good the code is and how well you keep the key secret.
