Password Conversion

Description

This project is about creating a program that converts passwords hashed in MD5 to plaintext, and then hashes them back to SHA256. To do this, it uses a wordlist to brute-force the MD5 hashes.

This is used to migrate the password format of an application from MD5 to SHA256, increasing security without requiring all users to re-enter the password.

Prerequisites

• rockyou.txt wordlist (download)
• passwords.txt md5 hashes list, passwords_example.txt is provided

Usage

1. Run python ./password_conversion.py
2. Wait until plain.txt is created
3. Wait until new_passwords.txt is created
4. Be patient pls, it may take some minutes :)
