Yes, you are correct, it was meant to expand the search range, like you said, be able to solve 160.

However, I am pretty sure it had bugs or speed was lost. I'm not sure it he has tinkered with it any more since his original post.

Check out Etar's kangaroo version; it is same as JLPs (but trailing DPs; zeros at the end) but can solve up to 192 bit range.

Hi WanderingPhilospher, thanks for the quick answer

Actually the 256 version is not working, i cloned the code from the Ripo and build it with CUDA 12.3 & sm_86 and tested it with the same example from JeanLucPons
This one

Code:

49dccfd96dc5df56487436f5a1b18c4f5d34f65ddb48cb5effffffffffffffff

The original JeanLucPons Kangaroo took 1:30 to find both minute while this 256 version didn't find anything even after 20 min ... therefore i think its not helpful.

Regarding the Etar's kangaroo .. you mean this one https://github.com/Etayson/Etarkangaroo ?
I wonder why there is no source code

what do you mean with this "trailing DPs; zeros at the end" can you explain more please

Regards

The source code is there. It's built with PureBasic. Nice, simple, clean code.

DPs can be at the beginning, middle, end.

JLPs DPs (Zeros) are leading, meaning they are at the beginning. I believe Etar's are trailing, at the end.

So JLP DP 20 = 00000xxxxxxx
Etar's DP 20 = xxxxxxx00000

It doesn't matter if they are trailing or leading. Both are good and work.

Test Etar's version out.
