hashcat gui md5 problem

[tori]

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

[tori]

I read it but I don't get it

I don't know how many letters and if it's upper or lower case

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?

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