secp256k1-node
This module provides native bindings to bitcoin-core/secp256k1. In browser elliptic will be used.
This library is experimental, so use at your own risk. Works on node version 4.0.0 or greater.
Installation
from npm
npm install secp256k1
from git
git clone git@github.com:cryptocoinjs/secp256k1-node.git
cd secp256k1-node
git submodule update --init
npm install
Windows
The easiest way to build the package on windows is to install windows-build-tools.
Or install the following software:
And run commands:
npm config set msvs_version 2015 --global
npm install npm@next -g
Based on:
Usage
const { randomBytes } = require('crypto')
const secp256k1 = require('secp256k1')
const msg = randomBytes(32)
let privKey
do {
privKey = randomBytes(32)
} while (!secp256k1.privateKeyVerify(privKey))
const pubKey = secp256k1.publicKeyCreate(privKey)
const sigObj = secp256k1.sign(msg, privKey)
console.log(secp256k1.verify(msg, sigObj.signature, pubKey))
* .verify return false for high signatures
Second pure js implementation
Project has yet one secp256k1 implementation based on elliptic and bn.js. The main purpose of this smaller size, high performance and easy code audit. This implementation is super experimental, use it at your own risk.
