@ecdsa123

I waited for a week, but there was no answer, so I misunderstood
I received the file, but I haven't tested it yet
I'm sorry for the misunderstanding.

@bjpark

check your e-mail.

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.

So your scrypts bullshit like many other scrypts

$1200 after payment i will send you my programm for re_change nonce to public for r,s,z

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

That 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.

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.

That's great.
Can we solve one more question?

It doesn't look possible because you still need the private key to compute s since s = k⁻¹(e + rd_U) mod n. where both k and d_u 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

COBRAS , in mathematcial way :

we have :

R: 3d9bc5aec4e53f59b03bc4866453a94b673e99f67bd69d2915a39964d4918a98

PubKey: 031ca4aa8c1bec706e817e9d74b356bcab13625061c541052ddd9e6352cba6911e

the question is: how to calculate new s and new z when we change:

r = 1ca4aa8c1bec706e817e9d74b356bcab13625061c541052ddd9e6352cba6911e
s = ?
z = ?

pubkey = 023d9bc5aec4e53f59b03bc4866453a94b673e99f67bd69d2915a39964d4918a98

?

you try simple replace r to pubkey ..

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

R iis like pubkey,you can bruteforce R like pubkwy
