cowpatty & cuda?

cowpatty use GPU or will use it in future ?

Perhaps. But why? You can use pyrit to 'passthrough' the generated tables and realize huge computing gains from your GPU. Here's just one example:

pyrit -e NETGEAR -f final-wordlist.txt passthrough | cowpatty -d - -r wpa-01.cap -s NETGEAR

Perhaps. But why?

for more speed when run "cowpatty -d" with precomputed (not passthrough)hash table (here we not use gpu's power with pyrit)

You are forgetting about the time it takes to pre-compute the table. It doesnt work like that. You dont seem to understand CUDA, it doesnt just "speed" up any old application. Its not steroids for all programs.

i have read that CUDA do math pallalel calculation on GPU 5x faster than cpu, and cowpatty use math calculation for test hash, same as pyrit calculate sha-1.

right, so , you can either use pyrit and pipe the hash's into cowpatty (which is already possible) , or you can completely rewrite and patch gempk (part of cowpatty , the hash generator) to compute the hash's and the use that hash table with cowpatty.

Seems silly to re-invent the wheel

As pureh@te has said before, the real power of pyrit and CUDA is in the speedy generation of the hash tables. Using pipes to passthru the tables to cowpatty is the real gain.

pureh@te -- Congrats on 5000 posts to the forums! Looking forward to many, many more from you!

and the use that hash table with cowpatty.

i know the passtrough, but if i have to use "cowpatty -d myhash .." and if there is the possibility to have more speed with GPU's use, why not?

Wait. We're kinda going in circles now.

Let me ask you: How did you generate 'myhash' in your command above?

If you DON'T use pyrit and CUDA, it took you a long time.

If you DID use pyrit and CUDA, it took less time.

The cowpatty application takes 'myhash' as one of its INPUTS.

Pyrit and CUDA generated 'myhash' quickly, as its OUTPUT.

Ok, I'm done.

DL from rainbow or calculate with pyrit or genpmk or calculate by hand is not the problem.
i only what to know if it's possible to speed up cowpatty (when process the just made hash) using the GPU.
