hashdog

Break MD5/SHA1/SHA256/SHA512 hashes using wordlists, password lists and string permutations.

Written in ES6/ES2015, and runs multiple forked processes for better performance. Using IPC calls in the cluster. Three different strategies are used for finding the correct hash. The first method is a english dictionary, along with a few word variations. The second path is using common passwords, while the third strategy is a bruteforce approach. The approach in this case is standard sequential recursive string permutation.

CLI

Install hashdog globally, sudo npm install hashdog -g. Root permissions needed to extract a data archive (used by the dictionary worker).

Run Hashdog in your terminal (run with no arguments for help screen):

hashdog 6d86ca3c74636711371637c2d73ec3e48dd1737a

node

Import and instantiate Hashdog (you might need to transpile the codebase from ES6 due to lack of support for modules and other features):

import {HashDog} from 'hashdog';
let hashDog = new HashDog({hash: '2655dd21148f2433763d313407d5d820', type: 'MD5', length: 8, chars: 'AaBbCcDdEeFf'});
hashDog.on('success', (data) => {
    console.log(data.hash + ':' + data.string);
});
