Yes, there is Wink

Have a look at -i, --increment-min and --increment-max as described here:
Code: (https://hashcat.net/wiki/doku.php?id=hashcat#options)
 -i, --increment                |      | Enable mask increment mode                           |
     --increment-min            | Num  | Start mask incrementing at X                         | --increment-min=4
     --increment-max            | Num  | Stop mask incrementing at X                          | --increment-max=8

So, if you know the password is between 6-8 chars...

Code:
hashcat -m 22500 -a 3 multibit_hash.txt -i --increment-min=6 --increment-max=8 ?a?a?a?a?a?a?a?a

will only check the masks that have 6-8 chars in them Wink

Ah OK, thanks for that. I never really understood how --increment worked and I thought it took a mask, and then made the mask shorter as in less characters. That's what the hashcat wiki page seemed to imply at least, in the part where it talks about having an 8 character mask but the mask's length decreases. Maybe that's what happens if you use -i and --increment-max by themselves?
