Subject: Mask mode for GPU

Hello ,

I read about the mask mode from here:

The mask mode explained above is I guess slightly different from what we 
need for GPU. Alexander mentioned before we need to take into account 
the keys generated on cpu. Then use the mask to multiply the keys in GPU.

To implement mask mode what are the parameters that we need to take from 
user? e.g keyspace size, mask etc ?

How do we apply the mask on the keyspace ? For example: when I get a key 
say 'abcdefgh'(generated on cpu)  and a mask say '?d?d' at what position 
in the key are we supposed to apply the mask ? Do we append the mask or 
replace the charters at those positions ?

Please discuss these issues.
