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.
npm install secp256k1-pure
git clone git@github.com:davidmurdoch/secp256k1-pure.git
cd secp256k1-pure
npm install
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
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.
