@NotATether help me this is your post 10/10/21 i need tips and python code: https://bitcointalk.org/index.php?topic=5364939.msg58145174#msg58145174
Implement a check before you do the modulus (I assume you made your own Point class) looking something like this:
This will make your point addition much slower but it's also the only way to detect whether the addition went outside the field.
my problem for any random public key add,sub.div,multple output is unknow 3rd publickey (x,y)ok, next 3rd publickey (x,y) in get y value find even odd value is small or big range how to find any math algebra code

iknow random private key: how to find y is small range or big range atleast guess
yellow color is private key is base x value , then you find which one small range y bigrange y

1. Is it possible to know when the point addition process has gone outside of the field?
Implement a check before you do the modulus (I assume you made your own Point class) looking something like this:
Code:
x = # x point calculation
y = # y point calculation
if x > p_order:
print("X out of range: {}".format(x))
if y > p_order:
print("Y out of range: {}".format(y))
x %= p
y %= p
y = # y point calculation
if x > p_order:
print("X out of range: {}".format(x))
if y > p_order:
print("Y out of range: {}".format(y))
x %= p
y %= p
This will make your point addition much slower but it's also the only way to detect whether the addition went outside the field.
