secp256k1-node

Version

cryptocoinjs/secp256k1-node's browser implementation (uses 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-pure

from git

git clone [email protected]:davidmurdoch/secp256k1-pure.git
cd secp256k1-pure
npm install

Usage

• API Reference (v3.x)

const { randomBytes } = require('crypto')
const secp256k1 = require('secp256k1')
//   if you want to use pure js implementation in node

// generate message to sign
const msg = randomBytes(32)

// generate privKey
let privKey
do {
  privKey = randomBytes(32)
} while (!secp256k1.privateKeyVerify(privKey))

// get the public key in a compressed format
const pubKey = secp256k1.publicKeyCreate(privKey)

// sign the message
const sigObj = secp256k1.sign(msg, privKey)

// verify the signature
console.log(secp256k1.verify(msg, sigObj.signature, pubKey))
// => true

* .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.
