hashcat Forum

Hi everyone,

Im getting new with hashcat... anyway Im trying to crack a DES hash with a nvidia Geforce 335M (notebook) but the speed seems to be really slow (2200 k/s). Testing with the examples included in hashcat plus and lite the speeds doesn't pass the 30000k/s. This is a "screenshot" of my try...

How I can improve this speed, drivers problem, hardware, options, sintax, any tip???

Thanks for your time!

First of all, thank you for masking your hash. Second, its not a really powerful card and DES is crazy slow.

There are two things wrong here: the first is "Nvidia", and the second is "notebook." Nvidia GPUs are slow enough as it is, let alone their mobile GPUs.

A good solution would be to get a desktop or server with an AMD GPU or four, and ssh into it from your notebook so you can crack when mobile.

:O Ok, thanks for the comments and aclaritions
