Hello everyone,

I am a forensic student and my final project is to find a password. I don get any help from the professor so it is difficult to do this task and I need your help! 

    • In this step, you need to use the provided wordlist.txt file.FSCS315 Final projectImage001: BitLocker encrypted image file. This file was generated from a BitLocker encrypted flash drive by FTK Imager. That means it has a password
      • FSCS315 Final projectImage.txt: A metadata file.


      • wordlist.txt: The file contains key space. (A list of all possible passwords)

      To break the encryption, two steps are needed:

      Step 1-Extract the hash: Use the bitlocker2john tool to extract the hash from the password protected BitLocker encrypted volumes.

      • That means you need to find the tool and figure out how to use the tool.
      • You must complete this step first to proceed to the next step.

      (Notes: You must put the image file in your computer's local drive. If you put the image file in One Drive, it will not work!)



      Step 2-Attack: Use the tool HashCat to attack the hash and get password

      • In this step, you need to use the provided wordlist.txt file.


     Based on this information, anyone can help me?

    Thank you!

The task is very straight forward, which part is causing difficulties for you? There are just two steps:



Run the program "bitlocker2john" on your encrypted image file to extract the hash:


Usage: ./bitlocker2john -i <Image of encrypted memory unit>


-h Show this help
-i Image path of encrypted memory unit encrypted with BitLocker



Attack the extracted hash with "hashcat" using the provided wordlist:

Read hashcat's help page to construct the command: 

hashcat --help

Find out the ID of the hashmethod to crack BitLocker: 

hashcat --help | grep -E -i bitlocker
22100 | BitLocker | Full-Disk Encryption (FDE)

Construct the command, it could be something like this:

hashcat -O -m 22100 -a 0 -w 3 extracted_hash.hash wordlist.txt -o cracked_password.txt

-O --optimized OpenCL kernels (max pwd length 32 symbols)

-m --hashmethod

-a --crack method (0 for standard dictionary, 3 for bruteforce)

-w --resource allocation (3 for high)

-o --output file


Have fun!
