not coded by me...im copy and pasting to be helpful, and the word "I" dose not refer to me but the person how posted it.

a quick (as in i made it quickly, it's not particularly quick ;P) md5 cracking class. I made it for part of a bigger project which I am real excited about, but I can't tell you about it yet :D
I changed the charlist to a-z because it broke the frame, you can add chars to the variable 'self.charlist' inside_init_

Code

import hashlib
class crack :
    #by yipyipchompchomp
    def __init__(self) :
        self.charlist = ["a","b","c","d","e","f","g","h","i","j","k","l","m","n","o","p","q","r","s","t","u","v","w","x","y","z"];
        self.charlen = len(self.charlist);
        self.hash = {};
        self.crackedHash = "";
        self.stop = False;
    def perm(self,n) : #permutation, only called by comb
        for i in range(1,n) :
            n = n*i;
        return n;
    def comb(self,r) : #combination, gets all possible combinations
        return self.perm(self.charlen)/(self.perm(r)*self.perm(self.charlen-r));
    def crackHash(self,m,h) : # sets md5 to crack
        self.unknownHash = h;
        self.max = m-1;
        self.num = 0;
        self.crackedHash = "";
        for i in range(0,m) : # sets hash dict
            self.hash[i] = "";
        self.brute(self.max-self.num)
    def checkHash(self,h) : #only called by brute
        hashstring = "";
        for i in h:
            hashstring += h[i];
        if hashlib.md5(hashstring).hexdigest() == self.unknownHash :
            self.crackedHash = hashstring;
            self.stop=True;    
    def brute(self,n): #only called by crackHash
        if self.stop!=True :
            if n == self.max-self.num:
                for i in range(0,self.charlen):
                    self.hash[self.max-n] = self.charlist[i];
                    self.brute(n-1);
            elif n>0 :
                for i in range(0,self.charlen):
                    self.hash[self.max-n] = self.charlist[i];
                    self.brute(n-1);
            else:
                for i in range(0,self.charlen):
                    self.hash[self.max-n] = self.charlist[i];
                    self.checkHash(self.hash);
#example implementation
c = crack();
for i in range(1,8) :
    if c.crackedHash == "" :
        print i,c.comb(i);
        c.crackHash(i,"900150983cd24fb0d6963f7d28e17f72");
    else :
        print c.crackedHash;
        break;
