Etar - why are you even loading the hashtable into memory? It's wasted time. What if you have 100 GB of DP data?
@kTimesG? thanks for the competition, it was interesting.
I didn't write any additional tools for this puzzle. I used what was already on hand.
If we were talking about tens of thousands of dollars, then of course i would have to work.
The only thing I changed JLP Kangaroo v1.7 so that it would only produce wild kangaroos.
Hash table with DP=20 weighs about 7GB, and loading time is 36s.
LoadWork: [HashTable 7449.0/9315.7MB] [34s]
My transformation steps:
03a61fc84b6429f07fc0edf25265ef7a0ced3cd9a0edea85e9f58b50b5d73f66e7 - minrange = 03634641685eca3f8284bcd4ddf233dac92a551bb5ff74a0b3fd587d4da7c13eea
03634641685eca3f8284bcd4ddf233dac92a551bb5ff74a0b3fd587d4da7c13eea / (2^361) = 0334a20e64c9a70138783b125ad81196c76585403905dda56a644ac83ac9620045
0334a20e64c9a70138783b125ad81196c76585403905dda56a644ac83ac9620045 in range 1..2^80
The private key from the kangaroo was 0x2d56cbf370cbeef9e80a
(0x2d56cbf370cbeef9e80a * (2^361) + minrange)%N = 0xb40e7d34265ab9533a64622bd1a188fb8abb8829af545169abad49b46be5fe56
