Speeding up bruteforce cracking time

[Leaver77]

Thanks for your reply. Im already using -1 ABCDEFGHJKMNPQRTUVWXY346789
Should the numbers be in -2 not in -1?
When im looking at the hashes it is trying, its trying everything, i dont want it to look
Through hashes with 0 or 1 or 2 or 4 or 5 or 6 or 7 or 8 numbers. Only 3.
The 3 numbers that are there could be in any position.

My masks are ?1?1?1?1?1?1?1?1
