Matt, a forensic analyst, wants to obtain the digital fingerprint for a given message. The message is 160-bits long. Which of the following hashing methods would
Matt have to use to obtain this digital fingerprint?

A.
SHA1

B.
MD2

C.
MD4

D.
MD5

Explanation:
The Secure Hash Algorithm (SHA) was designed to ensure the integrity of a message. SHA is a one-way hash that provides a hash value that can be used with an
encryption protocol. This algorithm produces a 160-bit hash value. SHA (1 or 2) is preferred over Message Digest Algorithm.
Incorrect Answers:
B: The Message Digest Algorithm (MD) also creates a hash value and uses a one-way hash. It produces a 128-bit hash.
C: MD4 is another version of the Message Digest Algorithm and produces a 128-bit hash.
D: MD5 is another version of the Message Digest Algorithm and produces a 128-bit hash.
