Question

Quizplus · Accepted Answer

Knowledge of the hashing algorithm does not give any knowledge of the original password. Hashing is a one-way function that generates a fixed-length string of characters from the input. It is designed in a way that it is difficult to reverse engineer and determine the original input. The purpose of hashing is to provide a secure way of storing passwords in a system. When a user enters their password, the system hashes the input and compares it to the hashed value stored in the database. If the hashed values match, the user is authenticated, but the original password is never retrieved or revealed.
