Is not strange the puzzle 40 is always found in a second with subtracted keya what is your question?

With the previous version it is working correctly.
I get the right pubkeys in KEYFOUNDKEYFOUND.txt.

Is not strange the puzzle 40 is always found in a second with subtracted keya what is your question?

The pubkeys that are writed in KEYFOUNDKEYFOUND.txt are not correct in the last version. They are not in hex format and they also start by 30 instead of 02 or 03. Therefore we can't find the corresponding pubkey index in the original file in order to make the math operation to get the final PrivKey.

Ohh yes i didn't notice the bug in the publickey, Is alredy solved in this commit 1060958,

Can you update your code to check if this fix solve your issue?, BTW don't forget backup your custom file 40_xpoints.txt

please letme know if it solve the problem for you.

Yeah it is working now! The pubkeys are correct and I can find the index to do the math operation. I get the right PrivKey at the end!

Thanks for the fix!
