Crack / Decrypt MD5 Hashes using Rainbow Table

Hello everyone, in this tutorial, i would like to give method how to crack, encrypt MD5 hashes using rainbow table.

What is Rainbow Table ?

A rainbow table is a precomputed table for reversing cryptographic hash functions, usually for cracking password hashes. Tables are usually used in recovering a password (or credit card numbers, etc.) up to a certain length consisting of a limited set of characters. It is a practical example of a space–time tradeoff, using less computer processing time and more storage than a brute-force attack which calculates a hash on every attempt, but more processing time and less storage than a simple lookup table with one entry per hash. Use of a key derivation function that employs a salt makes this attack infeasible.

so.. we can conclude what is rainbow table by this image :

Confused ? yha haha same with me, lol.
Alright, you will understand after watching this video :

Let's start

OK, after you read the explanation, watch that video... so it's time to try it.

If you use Windows, choose for Windows,

If you use Linux, choose for windows, hahah i mean Linux

In this tutorial, im using Rainbow Crack for Linux.

2. After Downloaded, unzip the Rainbow and go to that directory, see :

Not allow for execute the script ? type this command :

chmod +x rcrack rtgen rtsort

Now we have access to execute that script/program.

Waitt..... before running rtcrack script like that videos, you must have Rainbow Table first :).

Creating Rainbow Tables

Alright, before your create Rainbow Tables, you should see charset.txt, like this one :

Understand it ? must !

numeric                    = [0123456789]
alpha                        = [ABCDEFGHIJKLMNOPQRSTUVWXYZ]
alpha-numeric          = [ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789]
loweralpha                = [abcdefghijklmnopqrstuvwxyz]
loweralpha-numeric = [abcdefghijklmnopqrstuvwxyz0123456789]
mixalpha                  = [abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ]
mixalpha-numeric    = [abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789]
ascii-32-95                  = [ !"#$%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyz{|}~]
ascii-32-65-123-4            = [ !"#$%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`{|}~]
alpha-numeric-symbol32-space = [ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789!@#$%^&*()-_+=~`[]{}|\:;"'<>,.?/ ]

If you are lazy to create Rainbow table (it can take your times and make your computer hot)
you can download from my repository :

https://github.com/maxteroit/RainbowTable-alpha

or clone from my repository, use this command :

git clone https://github.com/maxteroit/RainbowTable-alpha.git 

 After cloning my repo, move all file (exc Readme.md) to directory which you save the Rainbowcrack files.

How to create Rainbow Table ?

Start creating Rainbow Table, use this command :
In here, im creating alpha charset for my rainbow table...

./rtgen md5 alpha 1 7 0 2100 8000000 all

The command means having the md5 hash type , plaintext length range 1 - 7, plaintext total 8353082582.

On process..

You can change plaintext range, plaintext total :).
If it done, you must short the rainbow table first, like this :

./rtsort .

 Ok, after that, run ./rcrack like the video, but wait, provide the md5 hash, or you can use my md5 :

ea1a3df96ef7de460929eecb5c521bad

Let's check in hashkiller.co.uk that my md5 hash :)
and the result is :

Not Found :p

Let's crack with our Rainbow Table and Rainbow Crack :D

Start cracking / decrypting MD5

Use this command :

./rcrack . -h ea1a3df96ef7de460929eecb5c521bad

Andd the result is.... CRACKEDDDD DECRYPTEDDD
