Explanation:
Hashing is used to prove the integrity of data to prove that it hasn’t been modified. Hashing algorithms
are used to derive a key mathematically from a message. The most common hashing standards for
cryptographic applications are the SHA and MD algorithms.
Incorrect Answers:
A: AES is not a hashing algorithm.
B: PGPis not a hashing algorithm.
E: ECDHE is not a hashing algorithm.Dulaney, Emmett and Chuck Eastton, CompTIA Security+ Study Guide, 6th Edition, Sybex, Indianapolis,
