The size to search in (and the keys which can be cracked) is determined by (end range - start range), second - first line.

Any range bigger than 125 bits currently isn't possible. The range variable itself has 126 bits free but there is some operation I can't recall right now that's done on it which limits the range to 125 bits.

I'm working on a patch to fix this. I have no ETA for it though, but I would like to get it ready within a week or two.

Yes (if for loop iteration counts as simultaneous Only the GPU truly cracks the keys simultaneously up to a certain number at once)


Yeah that looks about right, if it doesn't work, pad them with zeros on the left until they are 64 characters long each.



  That's very cool, first time I saw one interested in discrete log solvers.
