hii hackers,

Today, In this Post I am going to write about what is rainbow tables and How rainbow tables create password cracking more easy?

Introduction Of Rainbow Table

Q 1. What is Rainbow Table?

Ans. As The Name Suggest, Rainbow Table Is One Type Of Pre-Computed Table Of Hash Data For Several Hash Algorithms To Reverse The Hash Algorithm Cryptography Functions. Basically, In This Concept, A User Use A Pre-Computed Hash Table To Find Real Plain Text From Hash Value. In Modern World, Rainbow Table is One The Most Popular And Extremely Successful Way To Crack Any Hash Value Within Minimum Time And Minimum Computer Processing Power.

Q 2. How Rainbow Table Works So Fast?

Ans. As I Already Described Above, Rainbow table Use Pre-Computed Hash Value To Reverse The Process Of Hash Algorithms. So, Obviously This Method is Extremely High-Speed If Compared To Other Methods Of Password Cracking. Other Methods Like Brute Force Attacks, Dictionary Attack Or Hybrid Attack. Many Modern Password Cracking Software's are Now also Supporting Rainbow Table Concept For Cracking Passwords In Minimum Times. In my Opinion If You are a Penetration Testers, Hackers or  Cracker. Then, This Concept is Really Very Interest Thing For You But If You are A normal Internet User Then This Concept Is very Important To You also because this concept can cause big problems for your privacy policy.
