Which version of hashing algorithm uses a mathematical formula to reduce a message to 160 bits and then hashes a digital signature to go with the message?
A) MD2
B) MD4
C) MD5
D) SHA-1

Question

Quizplus · Accepted Answer

The hashing algorithm that uses a mathematical formula to reduce a message to 160 bits and hashes a digital signature along with the message is SHA-1. It is still considered secure, although there are newer versions of SHA available. MD2, MD4, and MD5 are all older hashing algorithms that are now considered less secure and have had successful attacks against them.
