Already known areas of hash
So lets say i have a password: test##123

I KNOW that there are 2 #'s in the middle

how can i make it so that there will always be 2 #'s in the guesses. 

Yeah i could use a rule, but im using MASK ATTACK, and it wont let me use a rule 

So please, is there any way I can do this?
Nvm: its on the mask attack page TOWARDS THE BOTTOM (for future peeopl) just some bad seo
