Package Exports
- secp256k1-pure
- secp256k1-pure/elliptic.js
- secp256k1-pure/index.js
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 (secp256k1-pure) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
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 git@github.com:davidmurdoch/secp256k1-pure.git
cd secp256k1-pure
npm installUsage
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.
