Custom charset help

[gpunerd]

Hi guys,

I'm trying to bruteforce a pdf hash, I know which characters are used in password, but do not know password. I have tried multiple commands but none of them is working. Here are the cmds:

Code:

hashcat -m 10500 -a 3 hash -1 WNRCEOIDLHwnrceoidlh0123456789

error: If you specify a custom charset, you must also specify a mask.

Code:

hashcat -m 10500 -a 3 hash --increment --increment-min=6 --increment-max=14 --custom-charset1 WNRCEOIDLHwnrceoidlh ?d

error: Invalid mask

Code:

hashcat -m 10500 -a 3 hash --custom-charset1 WNRCEOIDLHwnrceoidlh ?d

error: The wordlist or mask that you are using is too small.
