Package Exports

simple-js-ecdsa

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-ecdsa) 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-ecdsa

this project is intended as an easy to use ecdsa

creating a new identity

const identity = Identity.new()

if you would like to use a curve besides secp256k1

const ECMath = require('simple-js-ec-math')
const g = new ECMath.ModPoint(x,y)
const curve = new ECMath.Curve(<a>, <b>, <n>, <p>, g, <preprocessing>)
const identity = Identity.new(curve)

opening an existing identity using a private key

Identity.fromKey(<private number>, <curve?>)

opening a identity using a wif

Identity.fromWif(<private wif>, <curve?>)

opening a identity using sec1

Identity.fromSec1(<private wif>, <curve?>)

retrievable items in a identity

identity.key
identity.sec1Compressed
identity.sec1Uncompressed
identity.wif
identity.address
identity.compressAddress

signing a message

const signature = identity.sign(<message>)

verify a signature

identity.verify(<message>, <signature>)

signing in bip66 format

const signature = identity.signBip66(<message>)

verify bip66 signature

identity.verifyBip66(<message>, <signature>)

verify address

identity.validateAddress(<address>)

get public point

identity.publicPoint

key exchange

<identity>.keyExchange(<identity>)
