Question 22
Which of the following is NOT a commonly used cryptographic hashing algorithm?
- A AES-256
- B SHA-512
- C MD5
- D SHA-256
Reveal correct answer
Correct answer: A
Explanation
AES-256 (Advanced Encryption Standard, 256-bit) is an encryption algorithm, not a hashing algorithm. In contrast, MD5, SHA-256, and SHA-512 are cryptographic hashing algorithms used to generate fixed-length hash values from input data. Hash functions are commonly used for integrity verification and password hashing, whereas AES is used for encrypting data.Discussion
