Tool to generate rainbow tables which utilise GPU

[Si1eNce]

I am wishing to generate rainbow tables for various hashing algorithms, NTLM and MS Cache in particular. I am fully aware that the MS Cache hashes are salted with the username and therefore wish to create a rainbow table for general usernames such as Administrator.

I benchmarked my CPU to do a full character set for passwords which have a length of 1-8 characters which resulted in about 2000 years. Unfortunately, I do not have this amount of time to spare. I have therefore embarked upon attempting to use CUDA to solve this problem, are there any existing tools which can generate tables utilising the algorithms mentioned above which utilise the GPU or am I going to have to attempt to port code to CUDA?

Cheers for any help received.

Let me google that for you
Purehate did a good how to about all apps that work in pentesting using CUDA
