A silly & effective MD5 cracker in Python

PyBozoCrack

PyBozoCrack is a depressingly effective MD5 password hash cracker with almost zero CPU/GPU load written in Python. Instead of rainbow tables, dictionaries, or brute force, PyBozoCrack 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. Go ahead and try.

How?

Basic usage:

$ pybozocrack -f my_md5_hashes.txt

Or:

$ pybozocrack -s fcf1eed8596699624167416a1e7e122e

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:

$ pybozocrack -f 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.
