            cryptWord = crypt.crypt(word, salt)
            if (cryptWord == cryptPass or hashlib.sha512(word) == cryptPass):
                print "[+] Found Password: " + word + "\n"
                return
        print "[-] Password not found.\n"
        return

        for line in passFile.readlines():
            if ":" in line:
                user = line.split(':')[0]
                cryptPass = line.split(':')[1].strip(' ')
                print "[*] Cracking Password for: user[" + user + "]\n"
                testPass(cryptPass)
        return
    
    if __name__ == "__main__":
        main()
