That is not a 130-bit test, it's a 26-bit range, so the search is for a 26-bit private key that starts from some 130-bit offset (which size's is irrelevant).

26 bit is crackable in less than a second even if using slow-as-shit Python script, which is thousands of times slower than some native fast code.

It only takes around 5000 or so point additions to find the key.

this same test

Kangaroo 2.2 (JeanLucPons) : found the key in 15 seconds
Kangaroo 2.3 (256-bit) : 0.2 seconds
Etar-Kangaroo : no result
Rotor-Cuda: found key in 15 seconds - like Kangaroo 2.2


I am not sure if I am starting those tools with the correct options
