Mask attack with brain

[mtnsec]

What's your whole command line?

Originally I was using:

sudo hashcat -z --brain-password <pass> --brain-client-features 1 -a 3 -m 5500 -O hash.txt maskfile.mask

But after the explanation from royce I tried:

sudo hashcat -z --brain-password <pass> --brain-client-features 2 -a 3 -m 5500 -O hash.txt maskfile.mask

Changing the client features to 2 didn't make a difference at all. 

Thanks!!
