Hello friends. Inspired by the table on iceland's rsz, I created code in phyton for the cases where k,k+1...k+m. Since there is no such example whose private key I know, I ask you to check it. If it works, I will publish it on github. As far as I can see, there is no such resource, we can all benefit from it. Can anyone who sees it please check it out and give their opinions?

Code:

def h(n):
return hex(n).replace("0x","")

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

N = 0xfffffffffffffffffffffffffffffffebaaedce6af48a03bbfd25e8cd0364141

print (h(((S2*m*R1 + Z1*R2 - Z2*R1) * (S1*R2 - S2*R1)^(-1)) % N))

Syntax Error: There is a syntax error in the last line of your code. The ^ operator is used for bitwise XOR in Python, but it seems you intended to use it for exponentiation. For exponentiation, you should use **.

Incorrect usage of ^: Even after fixing the syntax error, using ^ for exponentiation won't work as intended. In Python, the correct operator for exponentiation is **.

Missing division function: The division in the last line of your code should be a modular division, but it's currently missing. You'll need to implement a modular division function to ensure correctness.

code: print(h(((S2 * m * R1 + Z1 * R2 - Z2 * R1) * modinv(S1 * R2 - S2 * R1, N)) % N))
