# Elliptic Curves over Finite Fields

Here you can plot the points of an elliptic curve under modular arithmetic (i.e. over $$\mathbb{F}_p$$).
Enter curve parameters and press 'Draw!' to get the plot and a tabulation of the point additions on this curve.
Interested in arbitrary curves over $$\mathbb{F}_p$$? Try this site instead.

Note: Since it depends on multiplicative inverses, EC Point addition will only work for prime moduli like 2,3,5,7,11,13,17,19,23,29,31,...,109,... ;-)

Draw the elliptic curve $$y^2 = x^3+ax+b \mod r$$, where

$$a$$: $$b$$: $$r$$:
