@chainx/keystore

@chainx/keystore encode private key to json format data with passphrase and decode json data to private key with passphrase.

How to use

import KeyStore from '@chainx/keystore'

const privateKey = '0xa3fd913a9606bb71b04e74ee6afe69b4154782cfc47c9076d041c7a4ab11cf9e'
const passphrase = '123456'

const json = KeyStore.encrypt(privateKey, passphrase)
const decodedPrivateKey = KeyStore.decrypt(json, passphrase) // equal to privateKey

The json format is as follows
