Hi,
Though this is feasible and as far as provide script for this I can develop but this is all computational. It require huge computation / process power and even after that how many years it can match a single address by chance, is absolutely a luck.
I am trying to break a gambling game that use 12 alpha/numeric random characters server seed and even that; is computed to take 3226266762397900000000 permutation and require 3226266762397900 days with good 8 core server to generate 1 million hash per day and require 35211270322 TB Storage Capacity to store all hash.
The permutation for 64 characters PVK is 36 to Power 64
5164973859965250000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000.00
which is almost impossible to generate and at the same time match x 2 efforts for even using complete amazon cloud computing to do so.
However if you want this for fun and try for luck, i can create the script.
Thanks & Regards
