I was testing on 2 signatures. both created with different K nonce.

as we all know, it will not lead to the correct private key unless the same nonce is reuse. However, i extended the code to include Babai's Nearest plane algorithm to readjust the wrong private key and get it closer to the correct private key by "guiding it " to the correct pubkey coordinates and it manage to only give me the partial private key from the closest vector.

I think this is interesting and will be exploring further to recover full private key.

result from my test.

Code:

At this point, the experiment is not completed and i only consider something viable if we can recover the full private key. if anyone interested to work with me on how we can refine this experiment further, do DM me.

hi,
i send your dm reply me
thankyou

hi Cassandra. Yes I have received your dm.. thanks.

Hi, bro

You need ask questions in crypto.stackexchangr I think.This will be more productive.

Hey man. How are you. Long time no talk. Yeah... I hate that place. They hate me too. It's mutual. We argued a lot there. Coz the admins was pretty rude. So I hack one of them
This was 4 years ago. Not interested to go back there.

I am waiting for 1 week. You are not replying; check DM and write your email.

#130 puzzles were solved by someone, and I think you solved.

he won't get anywhere with this!
