Lightning Hash Cracker

.
Estuve probando el LHC de Elcomsoft.
Basicamente es un password cracker que usa tecnologia CUDA para generar hashes MD5 a los palos.

English mode on: (I'm warned you about it)

Basically the Nvidia chip is a parallel procesor for mathematical operations. And this would be used like in 386 times, when some machines had a mathematical co processor.



In the above graphic you can see that it kills a normal processor performance in math ops, thats because the chipset is specifically designed to do the same math ops at really high speed in different data simultaneously.

Ok, some guys realized they could use that processing power to do other things instead of calculating doom 3 monsters, but they needed to use the normal graphics API , and that was a pain in the ass.

But Nvidia guys created a new API, just to use the parallel processing power of the board for simulations, or in this case, to generate hashes, the API is called CUDA (Compute Unified Device Architecture).

Actually I don't know what those commies registered, but using that API, ANY math op that is applied to multiple data, can be accelerated.

Bueno ahi arriba esta algo que habia posteado hace un tiempo, 30 de octube del 2007, que copado casi un año fue...
Bue, la idea es que en ese entonces los rusos como de costumbre ya tenian toolz privadas para bruteforcear MD5, nosotros nos creemos piolas pero cuando nosotros vamos los rusos ya estan de vuelta hace rato, algun dia capaz que me pongo a hablar sobre esto...

Veamos un grafico de hashes/segundo que nos entrega la tecnologia CUDA dependiendo que placa tengamos...



Y ahora mojemosnos un poco



Aca en esta pagina se pueden bajar 4 free el LHC http://www.elcomsoft.com/lhc.html
Yo lo estube probando un rato, tengo una Nvidia 8600 GTX y camina lindo tengo un average de 70.5 M hashes con un Intel Core2Duo 8400E.
Les cuento que por mas que usa la GPU le pega un castigo considerable al CPU tambien...
