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.
