This is just something like scientific interest. I previously spent a lot of time and resources trying to solve puzzle 120 and I'm still curious about its key.
I understand what you wrote, but I don't understand the real interest. Let's assume this is the real key for the 120bit puzzle 9C15FC66A182003BB1BE5D1DF12CAB
what did you gain from this insight other than the satisfaction of pure curiosity ?
