Certified Ethical Hacker (CEH) — Question 44

The network administrator for a company is setting up a website with e-commerce capabilities. Packet sniffing is a concern because credit card information will be sent electronically over the Internet. Customers visiting the site will need to encrypt the data with HTTPS. Which type of certificate is used to encrypt and decrypt the data?

Answer options

• A. Asymmetric
• B. Confidential
• C. Symmetric
• D. Non-confidential

Correct answer: A

Explanation

The correct answer is A, Asymmetric, because it involves using a pair of keys (public and private) for encryption and decryption, which is essential for secure communications over HTTPS. Options B and D are incorrect as they do not refer to any specific encryption method, and C, Symmetric, while used in some contexts, does not apply to the certificate type needed for HTTPS.
