Question

You are the Security Consultant and have been contacted by a client about its encryption and hashing algorithms. Their in-house network administrator says that the current hashing algorithm is an older algorithm with known weaknesses and lacks collision resistance. Which hashing algorithm are they most likely using?

A PKI
B MD5
C SHA
D Kerberos

Explanation

MD5 is a legacy hash algorithm for which collisions can be generated, so it no longer provides the collision resistance required of a secure cryptographic hash function. The U.S. National Vulnerability Database specifically identifies MD5 as not collision resistant.
