Package Exports

simple-js-ec-math

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (simple-js-ec-math) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

simple-js-ec-math

this project is intended to make easier and faster crytography projects. it is intended to be very lightweight and thus will not have many dependencies

to create a new curve to do math on:

const g = new ModPoint(
    bigInt('16'),
    bigInt('5')
)
const curve = new Curve(
    bigInt('9'),
    bigInt('17'),
    bigInt('23'),
    bigInt('23'),
    g,
)

g is your starting point on the curve with g you can do abstract math instead of 1 + 2 you would add g + 2g as an example

adding two points:

curve.add(g, g)

subtracting two points:

curve.subtract(g, g)

multiplication:

curve.multiply(g, 100)

doubling:

curve.double(g)

note division is not possible in elliptic curves. this is knows as the "elliptic curve discrete logarithm problem" (ECDLP) and is useful for security practices because it creates 1 way mathematics that are insolvable

to verify a point is actually a viable solution to the curve the verify function has been provided.

const point = curve.multiply(g, 100)
curve.verify(point)
