🎯 Learning Objectives 🎯

By the end of this room, you'll be able to:

🍅 Explain what cryptography is and why it matters for protecting confidentiality and integrity.
🍅 Describe the difference between plaintext and ciphertext with actual examples.
🍅 Explain what keys and algorithms are, and why keeping keys secret is critical.
🍅 Explain the difference between symmetric and asymmetric encryption using everyday objects, such as lockboxes and mailboxes.
🍅 Describe how symmetric and asymmetric encryption work together to protect your web browsing.

🎯 Room Tasks 🎯

🐱Task 1: Introduction

🐱Task 2: Hiding Information - Symmetric Encryption
- What's the flag you received after completing all levels of the Secret Message Rescue game?
- Using the Caesar cipher with a key of 5, what does CYBER become when encoded? (Uppercase, no spaces.)
- Using the Caesar cipher, find the correct key and decode the following secret message: FVZCYR PNRFNE PVCURE.

🐱Task 3: Sharing Keys Safely: Asymmetric Encryption
- In asymmetric encryption, which key stays secret?
- With asymmetric encryption, Alice can encrypt a message using Bob's public key, and only Bob's private key can decrypt it. Yay or Nay?
- What problem does asymmetric solve that symmetric cannot?
- After initial asymmetric exchange in HTTPS, what encryption type handles bulk data?
