Hey people!
I'm using Altcrack to find 66 but it only searches consecutively through 1 or some other number. Tell me if there is a program that can search for 66 puzzles by sorting through all the range options by mask.

for example this mask (decimal): XXXXXX123456XXXXXXXX

Now I have to run Altcrack 368,935 times consecutively to check the range for this mask, but this is very long. Is there any other way?
