Cracking Weak Passwords with Python: Building a Simple Brute Force Tool
Requirements: Kali Linux or Termux or any other linux
follow the below commands:

nano hash_cracker.py

paste the below code in that file

pip install hashlib

Install module like this if there is any module not found error

python pass_cracker.py

and then run the above script like this..
