Jack Hash Finder

Quick lookup for the original value of an hash

DEPRECATED

This repository is deprecated, go for the new version of jhf: https://github.com/jackrendor/jhf

Purpose

I was tired of looking up for common hashes values by hand. During CTFs you will eventually encounter some hashes. Instead of cracking them on your local machine or fire up a browser and look it up, the script does it for you. It tries some services to see if it's a common and known hash.

Supported hashes

Video Demonstration

Configure

Based on your distro, you should install first some dependencies.

Debian / Ubuntu

sudo apt install python3 python3-virtualenv

Fedora / RedHat

sudo dnf install python3 python3-virtualenv

Then simply execute the configure.sh file

bash configure.sh

or

./configure

Then you're ready to go. Simply execute the jhf file. You can pass the hash as argument:

./jhf 21232f297a57a5a743894a0e4a801fc3

You can specify more than one hash

./jhf b3ddbc502e307665f346cbd6e52cc10d 0bc11f2f3279555c317be9cf9e52645a

Or you can read from file by using -f or --file

./jhf -f report/hashes.txt
./jhf --file report/hashes.txt

No virtualenv

In case you don't want to use a virtual environment (which I discourage), install the python dependencies as user:

pip3 install --user -r ./requirements.txt

and DO NOT USE the jhf script. Just use the Python one:

python3 jhf.py
