# BozoCrack

BozoCrack is a depressingly effective MD5 password hash cracker with almost zero CPU/GPU load. Instead of rainbow tables, dictionaries, or brute force, BozoCrack simply *finds* the plaintext password. Specifically, it googles the MD5 hash and hopes the plaintext appears somewhere on the first page of results.

It works way better than it ever should.

## How?

Basic usage:

    $ ruby bozocrack.rb my_md5_hashes.txt

The input file has no specified format. BozoCrack automatically picks up strings that look like MD5 hashes. A single line shouldn't contain more than one hash.

Example with output:

    $ ruby bozocrack.rb example.txt

    Loaded 5 unique hashes

## Why?

To show just how bad an idea it is to use plain MD5 as a password hashing mechanism. Honestly, if the passwords can be cracked with *this software*, there are no excuses.
