secp256k1 secp256r1 sm2p256v1 keytools by js use sha256 for sign

Usage

const keyTools- = require('eckey.js');

newKeyPair

'use strict'
const assert = require("assert");
const keyTools- = require('eckey.js');

const key = keyTools.newKeyPair()
console.log(key)
assert(keyTools.privateKeyToPublicKey(key.priKey) == key.pubKey)

sign

'use strict'
const assert = require("assert");
const keyTools- = require('eckey.js');

let data = Buffer.from("Hello World!");

// keyTools.eck1 or keyTools.ecr1 or keyTools.ecsm2 (default)
const key = keyTools.newKeyPair()
console.log(key)
assert(keyTools.privateKeyToPublicKey(key.priKey) == key.pubKey)

//sign will sha256 of data
const sigStr = keyTools.sign(data, key.priKey);
console.log(sigStr)

//recover will sha256 of data
const recoverKey = keyTools.recover(data, sigStr)
console.log('recoverKey: ' + recoverKey)
assert(recoverKey == key.pubKey)
