I think you fall for some programs that you've seen which were generating huge amounts of keys per second,
and you think this is possible,
but they were fake.
I know how and what is generated. I need this for my experiment, but at this rate it's a perversion. And my hardware is quite powerful, 72 cores and 128GB of RAM. The same keyhunt, when brute force, produces 350 million keys at maximum load. But I need exactly this algorithm, hex separately from the public key. So that when I found a public key from the list, I knew its hex.
