Brute Force MD5 CTF Solver

This is a simple Python solution to brute-force an MD5 hash for CTF challenges using asynchronous HTTP requests. The code sends HTTP GET requests to a target URL, testing each possible MD5 hash character (hexadecimal) and then tries to find the flag from the server.

Requirements

• Python 3.x
• httpx library
• asyncio library

Installation

1. Clone the repository:

   git clone https://github.com/kn0x0x/brute-force-md5.git

2. Install the required dependencies:

   pip install httpx

Usage

1. Update the base_url in the main() function to point to the server you are trying to solve.
2. Run the script:

   python3 solve.py

The script will brute-force the MD5 hash of the flag by sending asynchronous requests to the server. Once the MD5 hash is fully constructed, it will attempt to fetch the flag.

Notes

• This script uses the httpx library to send HTTP GET requests asynchronously to improve speed.
• It brute-forces each character of the MD5 hash and then appends the flag.txt path to retrieve the flag once the hash is fully discovered.
