CompTIA Security+ (SY0-501) — Question 519

Which of the following is used to encrypt web application data?

Answer options

• A. MD5
• B. AES
• C. SHA
• D. DHA

Correct answer: B

Explanation

AES (Advanced Encryption Standard) is a widely used encryption algorithm that secures data, making it the correct choice for encrypting web application data. MD5 and SHA are hashing algorithms that are not suitable for encryption, as they do not allow for the original data to be retrieved. DHA is not a recognized encryption standard.
