GISF: GIAC Information Security Fundamentals

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?

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.
