Question

Quizplus · Accepted Answer

SHA-1 is no longer considered secure due to the development of faster computing machines and new methods of attack. In 2005, an attack was demonstrated that showed the possibility of finding collisions (two different inputs having the same hash output) in less time than was previously thought. As a result, experts have recommended the use of stronger hash algorithms such as SHA-256 or SHA-3.
