Code:

from sympy import mod_inverse
import secp256k1 as ice
pub=ice.pub2upub('0433709eb11e0d4439a729f21c2c443dedb727528229713f0065721ba8fa46f00e2a1c304a39a77775d3579d077b6ee5e4d26fd3ec36f52ad674a9b47fdd999c48')
N=0xFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFEBAAEDCE6AF48A03BBFD25E8CD0364141

k=mod_inverse(2,N)
neg1=ice.point_negation(ice.scalar_multiplication(1))

def ters(Qx,Scalar):
ScalarBin = str(bin(Scalar))[2:]
le=len(ScalarBin)
for i in range (1,le+1):
if ScalarBin[le-i] == "0":
Qx=ice.point_multiplication(k,Qx)
else:
Qx=ice.point_addition(Qx,neg1)
Qx=ice.point_multiplication(k,Qx)
return ice.point_to_cpub(Qx)

for x in range(1,65536):
print(ters(pub,x))

Hey man, I wanted to try your script but error is sympy module not found or doesn't exist. Any other way to get mod inverse working?

To install the `sympy` module on Windows, type CMD in the search bar and open Command Prompt and type
pip install mpmath, first and then pip install sympy.
put ice dll and secpt256k1.py in the same folder where you have the script.
