was crystal clear on the purpose of it , but i haven't tested my method (i know its not practical) with the Db yet
So if it's not practical why do you want to conduct it? For fun?
I think there's more atoms in the Milky Way than the number of random tries you'd need to make when using a 1 billion window to find a key in Puzzle 135. Is it not a linear search, basically? But instead of having one key, you have a 1 B window? Do you think that helps?
answer me on this one question what is the probability of hitting a random number that is in range 1B of the half of the target , even thought we are taking randoms until R>2^132 or R>2^133 .
