@nomachine - for another puzzle, do I need to change anything in the script other than keyrange and pubkey? Why am I asking you? Because, in order to test, I put the public key from #64 and a very small keyrange, between f7051f26b09112d4 and f7051f2ab09112d4 and it is obvious that the search is done outside the keyrange, in decimal, from 10000000000000000000 to 29999999999999999999
