Method#2 – Using John The Ripper

John the Ripper is the quick and robust password cracker, designed basically to crack Unix passwords. Along with Unix encrypted passwords, it further supports hashes on Windows LM with its open-source contributed patches. Windows user passwords are usually stored in SAM registry. The password is encrypted with NTLM hash in the SAM file. Then, SAM file is encrypted through SysKey. When Windows boots, the SAM file hashes are decrypted with SysKey and hashes can be loaded to the registry and used for the purpose of authentication. Both SAM and system files are not available to standard regedit programs when Windows run.

For encrypting passwords, NTLM has is too week. Here is the NTLM encryption algorithm and how it works –

  • Converts ASCII password to uppercaseNull padding is done until 14bytes
  • Then, it is split into two arrays of 7bytes
  • Making 64 bits (8-byte) by padding both to create DES key
  • The string “[email protected]#$%” is DES-encrypted with array for each 7 bytes and results in 8-byte stream
  • NTLM hash (16-byte) is formed with two cipertexts

As you see, the hashes are still not readable. So, it’s time to crack them with the help of John the Ripper software. It is one of the most widely used tools for Windows password cracking as well as for Mac OS X and Linux. All you need to download John the Ripper for Windows and extract it.

Go to Command Prompt and go to John the Ripper’s directory and type the following command –

john --format=LM d:\hash.txt
