Information!!!!
As per above discussion and blam on developers unfair
They provide you best freeware
Only mindset at public they want ready to eat
They don't have ability to create such app not able to apply math, nor able to apply brain
How they can use such app
Let me give u 1 more tip
Don't use start to end full bit range
Example
134bit to 135bit don't use
What to use
Split 135bit in parts of 70bit to 100 bits for run kangaroo in between, depand your gpu power
Or
Generate random number in 135 bit range and to set +100 bit for adjust range for checking key
A = 135 random generator
B = a+ 100bit range
Adjust a and b in your kangaroo command
Hope above small tips help you for use kangaroo and such app,
It's also help your mindset of kangaroo 125bit max etc
Enjoy!!!

Somewhat this approach can work (I was thinking about it too), but kangaroo is a probability algorithm, meaning it never finishes a range. You can never rule out a range. The only thing you can do is to search for a while and if you think you searched enough you try to search another range.

Don't fall for that guy, first he tells us to use our brain, than he offers the most idiotic advice in the Universe, splitting the range.

Ops needed if range split in N parts: N * sqrt(rangeSize)
Ops needed if range not split: sqrt(N * rangeSize) == sqrt(N) * sqrt(rangeSize)
Runtime increase if range is split: N / sqrt(N) == sqrt(N)

If 135 range is split into parts of 100, then it's 185363 times slower than if the 135 range is searched without splitting.

Dear
Without experiment speak is unfair,
First I explain for problem inside kangaroo where 125bit ...
Ihow to use.. for those who really want use kangaroo
2nd question
Rule out of range
For your test experiment
Generate 41 bit range public key
Set kangaroo command in between 39 to 40 bit range
You will found 41 bit range key out of range

Here in my view when you set command as per my said example above message
You set command is small portion of between 134bit to 135 bit and her your 125 bit problem will solve also your out of range is still under 134 to 135bit,
Don't worry you are not jumping out of 135bit range
Think again or get experience advice from senior developers those have these kind of tests
Don't be judged to quick
