This dcrypt calcs incorrect for your rsz in code and for my rsz too ...

Try it

Example, find signing secret.

My RSZ, K , Private Key is correct

Code:

r = 0xA0006BD73C2E587208D8A2BFDD3E650DC0307C6B6AFBFADA5A8434FBDF7FB6BE
z = 0x262316F1036B81F49DD1CA1891F1511C413E979FE87228E16D7F92CFF1E2619F
s = 0x302F58A8EE90236BE885CA8599666CA901097B7CAF1BF5D035B38EC06EB63AB8

The following are k and private keys, which can match the same group of rsz above

pvk = 0x0000000000000000000000000000000000011111111111111111111111111111
k = 0x6F66F604CDDE541F77A221AD403624084DCFED9D4E207CDDA1936511E1556933

k = 0xAFEDFACCD5489DBE4CDEA4BFEECAEC51D472169F5F86E59100B4182664BB584E

Here are your options.

Code:

def extended_gcd(aa, bb):
lastremainder, remainder = abs(aa), abs(bb)
x, lastx, y, lasty = 0, 1, 1, 0
while remainder:
lastremainder, (quotient, remainder) = remainder, divmod(lastremainder, remainder)
x, lastx = lastx - quotient*x, x
y, lasty = lasty - quotient*y, y
return lastremainder, lastx * (-1 if aa < 0 else 1), lasty * (-1 if bb < 0 else 1)

def modinv(a, m):
g, x, y = extended_gcd(a, m)
if g != 1:
raise ValueError
return x % m

I am sure more mathematically minded people can offer alternate arrangements.

Then @Krashfire find his nonce in 6 month, looks like he find I like in my calcs, but then he put small finded i to firmukas with z,s, modinv of s,z yes he get a nonce 256 bit, maybe I not right but finding 256 bit in 6 monts is imposible...

Tank you all for yours formulas,
I think formulas of k without point is , maybe interesting if replace x to 1 and see what's is going on....

Any more ideas ?

Now I not use original s and z , s= 1 because calcs of modular invercion give me error then modinv(0) and noot need edit all code for remove s and z from formulas:

nonce = 6

Someone understand how to find k from rsz+ pubkey +...... ?

find k must know rsz + private key

pvk = (inv(r) * ( (k*s)-z ) ) % N
k = (inv(s) * ( z + r * pvk ) ) % N
s = (inv(k) * ( z + r * pvk) ) % N
r = (inv(pvk) * ((k * s) - z ) ) % N

if r,s,z is the same, private key and k can be any combination ( 2^256 * 2^256 )

Code:

r = 0xA0006BD73C2E587208D8A2BFDD3E650DC0307C6B6AFBFADA5A8434FBDF7FB6BE
z = 0x262316F1036B81F49DD1CA1891F1511C413E979FE87228E16D7F92CFF1E2619F
s = 0x302F58A8EE90236BE885CA8599666CA901097B7CAF1BF5D035B38EC06EB63AB8

The following are k and private keys, which can match the same group of r s z above

pvk = 0x0000000000000000000000000000000000011111111111111111111111111111

There are 2^256 * 2^256 possibilities

You data with incorrect nonce, because you have different nonce with one r. For correct nonce k * G = P(r, y ).
This is a example for nonce, I not need d and z for finding nonce. Ttry too, calculate nonce with s= 1 and z = 0 ? Do you have same result for k ?

My next 3 messages will be a examples of my calcs. Ecamples with some of my technical result, need read first example , then next 2veill be simple for readings.

I am sure more mathematically minded people can offer alternate arrangements.

Nonce r from rsz is a X coodinate of publickbkey with privkey = nonce(k), is exact is a privkey of nonce pubkey R.

Nonce pubkey is calculatevin sage

R =E.Lift_x(r)

R / k = G

Question, what is a formula of r from rsz ?

Someone understand how to find k from rsz+ pubkey +...... ?

One of way for finding k , I think is disassemble a Lift_x function. IF this function not a simple calculation of seco256k1 formula of point coordinates with given X maybe has a way to solve
