CompTIA Security+ (SY0-501) — Question 270

Which of the following is used to validate the integrity of data?

Answer options

• A. CBC
• B. Blowfish
• C. MD5
• D. RSA

Correct answer: C

Explanation

MD5 is a widely used hash function that produces a 128-bit hash value, which helps verify data integrity by generating a unique checksum for a given input. CBC (Cipher Block Chaining) is a mode of operation for block ciphers, Blowfish is a symmetric-key block cipher, and RSA is an asymmetric encryption algorithm, none of which are primarily focused on validating data integrity.
