    Hi guys,
    [align=center]Edited[/align]
    A simple tool for cracking MD5 passwords.
    you need a dictionary file with this script.
    Password dictionaries

    #!/usr/bin/python

    about = \"\"\"
    ##########                       ##########

    \"\"\"

    import hashlib, sys

    def cracking() :
      
      encrypted = str(sys.argv[0])
      count = 0
      
      try :
        dict = open(sys.argv[1], \"rb\")
        buffer = dict.read().splitlines()
      except :
        print \"\n\t[-]Sorry, it can't open dictionary file\"

      if len(encrypted) == 32 :
        out = \"\n\t[+]MD5 --->\"
      else :
        print \"\n\t[-]Sorry, this is not md5 hash\"

      try :    
        while True :
          md5 = hashlib.md5(buffer[count])

          if md5.hexdigest().lower() == encrypted.lower() :
            cracked = buffer[count]
            print \"\n\t\t\tCracked!\n\"
            print out, encrypted, \"\n\n\t[+]Cracked --->\", cracked
            break

          else :
            count += 1

      except :
        print \"\n\t[-]Sorry, it can't crack this hash\"


    print about
    while True :
      cracking()


    Enjoy :)

    you've already imported sys, why not use argv statements instead of prompting?


    encrypted = raw_input("\nEnter MD5 encrypted for cracking >> ")


    replace this line with the following line so they can input the hash from the command line instead of being prompted for it:

    encrypted = str(sys.argv[0])

    also this line:


    dict = open("dict.txt", "rb")


    can be replaced with this line:

    dict = open(sys.argv[1], \"rb\")


    then the usage would look like:
    Usage: py md5crack.py hash dictionary

    That way the user isn't prompted to input both in separate instances, and they can just put all required info from command line.
    while( !(succeed = try() ) );

    Also just a note here, you may wanna add some usage messages. Like so:

    if len(sys.argv) != 3:
        print(\"Usage: %s <hash> <dictionary file>\" % sys.argv[0])
        sys.exit()

    Also another option would be to use the optparser module which would look like so:

    md5cracker.py -p hash -d dictionary file

    Thanks men :)

    That is a test version but full version coming soon.[hr]
    Main problem was :

    if md5.hexdigest() == encrypted :
      ...
      ...


    Edited to :

    if md5.hexdigest().lower() == encrypted.lower() :
      ...
      ...

    Thanks Xinapse, your welcome :)

    I didn't consider the speed on it because it's dictionary attack.
