I'm not sure what you mean by this but I would strongly suggest this as a starting point:

BTW, an i7 is nothing... just spend a week or so to learn Nvidia CUDA, rent a few dozen Amazon Web Services Cluster GPU instances and you will be frightened to learn how many hundreds of billions of password candidates (yes billions!) you can try in a few seconds. All at the hands of anyone with an AWS account. Makes you think at least twice about password security.
