What are MD4 and MD5?
A.
Symmetric encryption algorithms
B.
Digital certificates
C.
Hashing algorithms
D.
Asymmetric encryption algorithms
Explanation:
The correct answer is “Hashing algorithms”. Answers “Symmetric encryption algorithms” and
“Asymmetric encryption algorithms” are incorrect because they are general types of encryption
systems, and answer “Digital certificates” is incorrect because hashing algorithms are not digital
certificates.
