Intro

MDCrack is a powerful and fast hash cracker. It can brute force MD5, MD4 and NTLM1 hashes. MDCrack is terminal tool but there is a GUI available. It is available for Windows and for Linux.

How to use it

MDCrack is easy to use but first we will need a hash to test, you can generate one using your Linux terminal or a website like this one. In the following example i will be using arch Linux but the commands are the same for other distros too.

To calculate and md5 hash in linux you can use the following command :

echo -n [text to hash] | md5sum

I have already used this command to generate the hash to the word 'pass' and the result is 1a1dc91c907325c69271ddf0c944bc72

To crack the password type the following command :

mdcrack -M MD5 1a1dc91c907325c69271ddf0c944bc72

For help and more options type :

mdcrack -h

And then the hash will be brute forced. The time it takes to crack it depends on the size of the password, the password we used was short ('pass') so it was cracked quickly.
