hashcat Forum

Hello guy's !

I try to decrypt this hash :

$ethereum$s*262144*1*8*3436383737333838313035343736303637353530323430373235343034363130*8b58d9d15f579faba1cd13dd372faeb51718e7f70735de96f0bcb2ef4fb90278*8de566b919e6825a65746e266226316c1add8d8c3d15f54640902437bcffc8c3

(password=hashcat)

with the command line : hashcat64.exe -m 15700 ETH.hash MDP.dict

But i have an error !

Have an idea ?

Good night !

Try again with --scrypt-tmto 2. If it works, it's a driver error. Note that it can take some time to start. Also try -D 1 separately.

Thanks atom.
It's working with --scrypt-tmto 2 !!

But i have an other error : CL_OUT_OF_RESOURCES
I follow this tuto : https://hashcat.net/wiki/doku.php?id=timeout_patch
and now it's okay.

but ... when i try with a small dictionnaire (77 password) it's okay. and the password was found !
when i try a "big" dictionnary (19000 password), the PC freeze (about 10 min)
when i try brute force with -a 3. PC freeze.

what is your suggestion ? old driver ?? Currently i have 382.53.

Good night !

The pc does not freeze, it just looks like that. That is because the GPU is so busy with this algorithm it has no clocks left to update the screen for the monitor. The solution is to run hashcat on linux and connect to it via SSH.

"The solution is to run hashcat on linux"
Oh yes ! i know how to do !

" and connect to it via SSH. "
Euh ...

What is the objective ? Do you have a link for a tutorial please ??

or... Maybe, I should expect a stable version of hashcat?

Hashcat is stable, but you're trying to use the same GPU for compute while also driving your display. It can't do both. That's why the display freezes, it's too busy cracking passwords to push pixels. The solution is to only use the GPU for password cracking, thus SSH'ing into a headless Linux system eliminates the issue of the GPU having to push pixels.

If your motherboard has onboard video, you could try making that your primary video. Another option to try if you have an extra PCIE slot, pick up an older cheap GTX video card, and use it only to drive the display. Then your two 1070s would be solely for compute. If neither of those are options for you, then atom and epixoip have the answer above.

@tacohashcat !!

Good idea !! I will test this !!!

magimix how did you get the hash? i see all the similar stuff in the wallet but cant see how to put it all together.
