is there any way to change that r will be pubkey , and pubkey will be R ?
I mean nonce is pubkey , pubkey is nonce?

Copy Paste not work for you ? ![Cheesy](https://bitcointalk.org/Smileys/default/cheesy.gif) R iis like pubkey,you can bruteforce R like pubkwy

COBRAS , in mathematcial way :
we have :
R: 3d9bc5aec4e53f59b03bc4866453a94b673e99f67bd69d2915a39964d4918a98 S: 28637de6101936def68c0cfd831c7a73227b8ba7ef1c70ddba6e69d2e628775a Z: f3612c362cf925c4dc902957353454bf04bdcc3e874372800a8e69f6daa7a19f PubKey: 031ca4aa8c1bec706e817e9d74b356bcab13625061c541052ddd9e6352cba6911e
the question is: how to calculate new s and new z when we change:
r = 1ca4aa8c1bec706e817e9d74b356bcab13625061c541052ddd9e6352cba6911e s = ? z = ?

you try simple replace r to pubkey ..

It doesn't look possible because you still need the private key to compute s since s = k−1(e + rdU) mod n. where both k and du here would be the private key which you don't have.

Hello no possible but cannot reach the desired result. Let me show you the possible result. r = 1ca4aa8c1bec706e817e9d74b356bcab13625061c541052ddd9e6352cba6911e s = 95acfc5533fc1693918a0ac0f03c62a2b0b1d30289d8769c66b37c2e85abbcbd z = 4bc17560a03e004105d48f22ecb8d7b620f0ba85d6619abcffad00a839216e9a pubkey = 023d9bc5aec4e53f59b03bc4866453a94b673e99f67bd69d2915a39964d4918a98 thank you.

Oh, that's amazing. Much research has been done on the rsz formula. I developed a calculator. for better calculation I want to buy your program I'd like to look into it. https://youtu.be/9i6cQOTYAkUthank you

Don't tell me you were actually trying to buy a signature breaker from him, were you? There is a free breaker that you can download here: https://github.com/Ledger-Donjon/whitebox_ECDSA_attack_tool

Don't tell me you were actually trying to buy a signature breaker from him, were you? There is a free breaker that you can download here: https://github.com/Ledger-Donjon/whitebox_ECDSA_attack_toolThat repository is totally useless for what people in this forum want, since it involves messing with the CPU while it does the original signing process. It can't be used for any already existing signatures.

@bjpark check your e-mail. ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) sorry for delay. to rest and to NOTaTether: yes he buy from me the script for changing nonce to privkey and privkey to nonce in transaction from r,s,z. and this script is working. ahh NotaTether: you wrote: "Don't tell me you were actually trying to buy a signature breaker from him, were you" -> signature breaker -> what do you mean? you mean "breaking ecdsa" ? sorry this script is not breaking anything. only rechanging signatures. nothing more. So NotAtether you are to fast to "description" other people you think you are "Legendary", but you are not. I hope you will understand that never say anything about people which you does'nt know.
