both script do same but feel pollard-kangaroo-multi.py work better pollard_kangaroo.txt
Very educational scripts you shared. It's dumbed down enough for someone to follow along the different stages (preparing the tame and wild herds within two different ranges, showing how the jump table of G points is made, converting the DP mask to a difficulty etc. which I leaned doesn't have to have all bits adjacent to it.
Something that's bothering me about Jean_Luc's program though is how we stuff the kangaroo type in the distance 128-bit number but we have a separate member "kIdx" in ITEM and DP structs that can be modulus'ed by 2 to give the kangaroo type - The kangaroos in a vector alternate between wild and time, which corresponds to what these scripts are showing.
It's also sending some useless stuff over the network to Kangaroo servers, e.g "h" the hash table index, this is useless because the hash table is local to one host, but it's stuffed in the "x" 128-bit member so it's sent anyway. Same with the kangaroo type which is already embedded in the lowest by of "kIdx", it makes no sense to put it in a hash entry struct as well, hash entries aren't even sent across the network. Nitty gritty details that complicate transitioning it to unsigned 256 bit.
That script can show newbies who interest or want to know how it works just setting to show message on working
script is one file easy to read too
old script but record to try use it study, try use with low key space and low number of puzzle under 40 bits fast to found and learn how it works
and What mean Kangaroo limited 120 bits
However all Kangaroo version have limited for 120 bits only right both Jean_Luc's program have problem with limited 120 bits.
if we solve puzzle #120 already so, What next?
how can extend 120 bits
or that mean limited wide of range scan for 120 bit and for high bit like 160 bits need to split 2 keyspace or 4 keyspace and scan each method use program something like that
Do I miss understands.
