Package Exports

@dcl/crypto
@dcl/crypto/dist/crypto
@dcl/crypto/dist/crypto.js
@dcl/crypto/dist/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 (@dcl/crypto) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

DCL Auth Crypto Lib

How to Install

  npm i @dcl/crypto

Create a new Identity using Ethers

import type { AuthChain, AuthIdentity } from 'dcl-crypto/dist/types'
import Authenticator from 'dcl-crypto/dist/Authenticator'
import { Wallet } from '@ethersproject/wallet'
import { Web3Provider, ExternalProvider } from '@ethersproject/providers'

/**
 *
 * @params provider - any ethereum provider (e.g: window.ethereum)
 * @params expiration - ttl in seconds of the identity
 */
export async function createIdentity(provider: ExternalProvider, expiration: number): Promise<AuthIdentity> {
  const signer = new Web3Provider(provider).getSigner()
  const address = await signer.getAddress()

  const wallet = Wallet.createRandom()
  const payload = {
    address: wallet.address,
    privateKey: wallet.privateKey,
    publicKey: wallet.publicKey,
  }

  const identity = await Authenticator.initializeAuthChain(
    address,
    payload,
    expiration,
    (message) => new Web3Provider(provider).getSigner().signMessage(message)
  )

  return identity
}

Create a new Identity using Web3x

import type { AuthChain, AuthIdentity } from 'dcl-crypto/dist/types'
import Authenticator from 'dcl-crypto/dist/Authenticator'
import { Eth } from 'web3x/eth'
import { Address } from 'web3x/address'
import { Account } from 'web3x/account'
import { Personal } from 'web3x/personal'
import { EthereumProvider } from 'web3x/providers'
import { bufferToHex } from 'web3x/utils/hex-buffer'

/**
 *
 * @params provider - any ethereum provider (e.g: window.ethereum)
 * @params expiration - ttl in seconds of the identity
 */
export async function createIdentity(provider: EthereumProvider, expiration: number): Promise<AuthIdentity> {
  const eth = new Eth(provider)
  const addresses = await eth.getAccounts()

  const provider = connection.provider
  const account = Account.create()
  const payload = {
    address: account.address.toString(),
    publicKey: bufferToHex(account.publicKey),
    privateKey: bufferToHex(account.privateKey),
  }

  const identity = await Authenticator.initializeAuthChain(
    addresses[0],
    payload,
    expiration,
    (message) =>
      new Personal(provider as any).sign(
        message,
        Address.fromString(address),
        ''
      )
  )

  return identity
}
