Description

CrackerHash is a program I developed originally for the purpose of demonstrating how inefficient brute forcing can be as the number of potential combinations increases, however can be an effective tool for reverse engineering MD5 hashes. It should be noted I take no responsibility for any activity you use this application for, it has been released as a means of data recovery and as an educational tool and I do not encourage this to be used for any illegal activity.

How to Use

Windows

If you are running Windows the easiest method is to download the Windows executable and simply:

1. Open a command prompt (Start > Run > Type “cmd” (without the quotes) and press OK) and then drag and drop the file into the command prompt.
2. Once the path to the executable appears in the command prompt add the following parameters to the end: –maxlength x –hash h (replacing x with the maximum number of characters to try and h with the MD5 hash you wish to crack)
3. After completing these steps press enter and CrackerHash will begin to brute force against the hash

The alternative to this (if you have Python installed) is to follow the steps above, but instead drag crackerhash.py into the command prompt in step 1.

Other Systems

CrackerHash will also work on any other system that supports Python such as Linux and OS X, simply follow the steps in the previous section, but in step 1 using the appropriate terminal window for your operating system and putting the command “python” before the file path.
