Password cracking programs reverse the hashing process to recover passwords. (True/False.)

The correct answer is B. False. Password cracking programs generally do not reverse the hashing process but rather attempt to find the original input that produces a matching hash.

Why each option

Password cracking programs generally do not reverse the hashing process but rather attempt to find the original input that produces a matching hash.

ATrue

This is incorrect because hashing functions are specifically designed to be irreversible; direct mathematical reversal of a hash to plaintext is not possible.

BFalseCorrect

Hashing is a one-way cryptographic function designed to be computationally infeasible to reverse, meaning you cannot directly derive the original plaintext password from its hash. Password cracking programs work by computing hashes of guessed passwords (e.g., from dictionaries or brute-force attempts) and then comparing those computed hashes to the target hash to find a match.
