Data encryption basics in Unity - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is data encryption?

Data encryption is the process of changing information into a secret code to prevent unauthorized access.

beginner

What is a key in encryption?

A key is a secret value used to lock (encrypt) and unlock (decrypt) data.

intermediate

What is the difference between symmetric and asymmetric encryption?

Symmetric encryption uses the same key to encrypt and decrypt data. Asymmetric encryption uses a pair of keys: one to encrypt and a different one to decrypt.

beginner

Why is encryption important in Unity games?

Encryption protects sensitive data like player info or game scores from being stolen or changed by others.

intermediate

What Unity class can be used for simple encryption?

Unity can use classes from the System.Security.Cryptography namespace, like Aes or RSA, for encryption tasks.

What does encryption do to data?

A Copies data to another file

B Deletes data permanently

C Converts data into a secret code

D Compresses data to save space

Encryption changes data into a secret code to keep it safe.

Which key type uses the same key for both encrypting and decrypting?

A Symmetric key

B No key needed

C Public key only

D Asymmetric key

Symmetric encryption uses the same key for both locking and unlocking data.

In Unity, which namespace contains encryption classes?

A UnityEditor

B UnityEngine.UI

C System.IO

D System.Security.Cryptography

Encryption classes like Aes and RSA are in System.Security.Cryptography.

Why should game data be encrypted?

A To protect data from unauthorized access

B To make the game run faster

C To increase file size

D To change game graphics

Encryption keeps game data safe from being stolen or changed.

Which of these is NOT a purpose of encryption?

A Protecting privacy

B Making data readable by everyone

C Preventing data tampering

D Securing communication

Encryption makes data unreadable to unauthorized people, not readable by everyone.

Explain in your own words what data encryption is and why it matters in game development.

Think about how you keep your personal info safe.

Describe the difference between symmetric and asymmetric encryption with simple examples.

Imagine locking a box with one key or two different keys.
