Yeah, I understood that there is a limitation until the moment. :~(
Fingers crossed to have a solution during next months...

I know mask mode very briefly, to say the true I know it exist because of
hashcat, but I don't understand it very well. I found this post and I guess
it's related:
http://www.openwall.com/lists/john-dev/2013/06/15/1
Where can I find a good documentation explaining how mask mode works,
advances in comparison with other modes, etc?
Thanks.
