If the two values are different, Maureen knows that the message was altered, either intentionally or
unintentionally, and she discards the message…As stated in an earlier section, the goal of using a
one-way hash function is to provide a fingerprint of the message. MD5 is the newer version of MD4.
IT still produces a 128-bit hash, but the algorithm is a bit more complex to make it harder to break
than MD4. The MD5 added a fourth round of operations to be performed during the hash functions
and makes several of its mathematical operations carry steps or more complexity to provide a higher
level of security . – Shon Harris All-in-one CISSP Certification Guide pg 182-185
