hashcat gui md5 problem - tori - 08-24-2012

hello,
I'm using hashcat gui cuda lite.
And I want to brute force a md5 hash.
For example hello that is no problem.
But if I write it upper case HELLO
The programm can not crack it. Exhausted
is displayed.

can anybody help me?

I guess you just ran with the default mask. To crack HELLO you need ?u?u?u?u?u. See here for a description: https://hashcat.net/wiki/doku.php?id=mask_attack

I used the mask ?u?u?u?u?u but it didn't work. I don't know why

ok thank you it works.
But if I don't know that that all upper case.
Lets say HEllo. And I don't know how many letters and if it's upper or lower case what mask sould i take?

So you don't know the password. And you did not read https://hashcat.net/wiki/doku.php?id=mask_attack

Start with a a dictionnary attack, and a bruteforce attack.

ok I've got another question.
Why is ati so much faster than nvidia in cracking with hashcat?


RE: hashcat gui md5 problem - Mem5 - 08-25-2012

It depends on your card. Each card is different. ATI are better because they have more cores.
