If your key was reused then it's possible to recover it. Then the time complexity is only 2⁴⁰, which is doable in 15 minutes on a V100 GPU.

Reused key means you sent coins from it, and know the public key.
Or if you signed anything and have the signature.

hi!  
How to run this tool ?
What a version of java need install?

[MixMAx123]

It should run with any Java version. https://java.com/de/download/

It is then started with a double click on the .jar file.   https://github.com/MrMaxweII/repairPrivKey/releases/download/V1.3.1/repairPrivKey.jar
