Certified Ethical Hacker (CEH v10) — Question 94

What is the difference between the AES and RSA algorithms?

Answer options

• A. Both are symmetric algorithms, but AES uses 256-bit keys
• B. AES is asymmetric, which is used to create a public/private key pair; RSA is symmetric, which is used to encrypt data
• C. Both are asymmetric algorithms, but RSA uses 1024-bit keys
• D. RSA is asymmetric, which is used to create a public/private key pair; AES is symmetric, which is used to encrypt data

Correct answer: D

Explanation

The correct answer is D because RSA is indeed an asymmetric algorithm used for creating public/private key pairs, while AES is a symmetric algorithm used for data encryption. Options A and B incorrectly classify AES or RSA's nature, and option C incorrectly states that both algorithms are asymmetric.
