Hashcat

[Terror1810]

Hey! i'm totally new to this site  so please bear with me. I'm using hashcat on windows to attempt to break a password. I am struggling to grasp the concept of the ?d?d?d? system. I KNOW the password is in ALL CAPS and contains a few numbers in it too, it's a password of 8 total, 

hashcat.exe -m 22000 -a3 hash.hc22000 ?d?d?d?d?d?d?d?d

Hey! i'm totally new to this site  so please bear with me. I'm using hashcat on windows to attempt to break a password. I am struggling to grasp the concept of the ?d?d?d? system. I KNOW the password is in ALL CAPS and contains a few numbers in it too, it's a password of 8 total, 

hashcat.exe -m 22000 -a3 hash.hc22000 ?d?d?d?d?d?d?d?d

?d => 0-9
?l => a-z
?u => A-Z
?s => a bunch of special chars
?h => 0-9a-f
?H => 0-9A-F

-1 ?l?u would be ?1 and would cover a-zA-Z

So if you know it's 8 chars consisting of uppercase and digits you would use smth like:

hashcat.exe -m 22000 -a3 hash.hc22000 -1 ?u?d ?1?1?1?1?1?1?1?1

where -1 ?u?d => ?1 => A-Z0-9
