Cryptography

Cryptography

Cryptography is a core part of Cyber Security. In this case file you'll learn what it is, why it matters, and how to use it in real code.

Understanding cryptography well means you can read other people's Cyber Security code with confidence, and avoid the most common beginner mistakes in this area.

Key points:

• What cryptography means in the context of Cyber Security
• A minimal example you can run or read in the playground on the right
• A common mistake to avoid when working with cryptography

# Cyber Security: Cryptography
# Reference material — read the notes on the left and follow along in your own environment.

Tip: Try changing a value in the code on the right and re-running it — small experiments are the fastest way to build real intuition for cryptography.
