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 ?

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.


1. Download RainbowCrack from https://project-rainbowcrack.com/

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
