ECDSA signing uses a random number called the nonce. A signature contains two numbers (r, S). r is generated only from the nonce and the nonce mustn't be reused. When the nonce is reused, r is the same too.

https://www.maximintegrated.com/en/design/technical-documents/tutorials/5/5767.html Eq 2 shows how r only depends on the S.

I don't know what you're referring to as Z.

  • Because I am currently collapsed and I want a solution. I lost my wallet in 2014 and I could not reach it. There are approximately 9 Bitcoins in it. I am looking for it and I could not reach it. I thought about committing suicide.
