mask attack with a max occurrence

[lloydXmas]

Thanks for your help. Can the maskprocessor limit the occurrence of a defined set of characters though? So let’s say I want to define a charset as such:

Code:

--custom-charset1=%#=+

And I want to generate all possibilities that contain none, one, or two occurrences of any character from that charset.
So for instance, these would be valid possibilities:

Code:

bnkrwcvt
bnk#wcvb
bnk#wcv%
bnk#wcv#
bnk++wcv

While the following would be an invalid possibility (as it contains three occurrences of charset1):

Code:

bnk#w+v%

Can I specify which characters I want to use with the --occurrence-max option?
