  • Advanced options: External (Import Key material)

  1. Click the Next button to go through the configuration of the labels, administrative and usage permissions, to finally click the Finish button at the end of the process.

  2. Select your Key spec and Wrapping algorithm or leave the default settings and click the Download wrapping public key and import token button. It will download a zip file with ImportToken.bin, README.txt and WrappingPublicKey.bin files in it.

BonneVoyager / restoreAccountFromWeb3SignedMessage.js
Last active November 16, 2022 15:46
Sign a message within web3 and then verify the signed message on the backend as a proof that the user doesn't impersonate for someone.
// First sign a 'message' on the frontend:
const web3 = new Web3(Web3.givenProvider)
const __message__ = 'abc'
web3.eth.requestAccounts()
.then((accounts) =>
web3.eth.personal.sign(__message__, accounts[0]) // this will return a 'signature'
)
// ... and then pass the message and the signature to the backend to recover public address of the signer:
const ethUtil = require('ethereumjs-util')
