Point P (x)

Point Q (x)

On an elliptic curve y² = x³ + ax + b, you "add" two points with a geometric rule: draw the line through P and Q, find where it meets the curve again, and reflect that point over the x-axis. Repeating this addition is easy, but reversing it — the elliptic-curve discrete log — is brutally hard, which is what makes ECC secure with far smaller keys than RSA.

Governing equation

y^{2} = x^{3} - 1.0 x + 1.0, λ = \frac{y _{2} - y _{1}}{x _{2} - x _{1}} = - 0.14

Reading this result: The secant through P and Q meets the curve at a third point; reflecting it across the x-axis gives P+Q. Repeating this is easy, but undoing it (the discrete log) is what secures ECC.

About this simulation

The full Elliptic Curve tool models a salt-and-hash with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.
