hashlib collision generator

To learn how to use hashlib in python, I made a little collision generator for brute forcing password hashes with a dictionary. If you really want a good brute-force tool go download john... but if you're interested in playing with python and hashlib, this was pretty fun.

import hashlib
import sys

dict = open(sys.argv[1], 'r')
hashfile = open(sys.argv[2], 'r')

hashes = hashfile.readlines()

for line in dict:
        h = hashlib.new('md5')
        h.update(line)
        test = h.hexdigest()
        print test
        for i in hashes:
                if i.rstrip() == test:
                        print 'match: ' + test + ' :: ' + line

The script takes two textfiles as arguments, the first being a list of words to use a dictionary, the second being a list of hashes to try to crack.
