Creates a new Ethereum Keystore

create_eth_keystore.js

// Usage: node create_eth_keystore.js
// Node v10+
// Dependencies
// npm i [email protected]

const Wallet = require('ethereumjs-wallet') 

const accountPassword = "" // Put here the password you want for your keystore
const key = Wallet.generate(accountPassword)
const privateKey = key._privKey
const wallet = Wallet.fromPrivateKey(privateKey)
const keystoreData = wallet.toV3String(accountPassword)

const address = "0x" + JSON.parse(keystoreData).address
console.log("Account Address:", address)

console.log("Public key:", wallet.getPublicKeyString())
console.log("Private key:", wallet.getPrivateKeyString())

console.log("Keystore:\n", JSON.stringify(JSON.parse(keystoreData), null, 2))

To get the public and private key from wallet as a String. You can also get them as a Byte[] removing String from the function

console.log("Public key:", wallet.getPublicKeyString())
console.log("Private key:", wallet.getPrivateKeyString())

Thanks! I have edited the code 😄
