npm i @rsksmart/rif-id-ethr-did

Features

• Manage DID v1.0 compliant identifiers for RSK BIP-44 schema
• Derive RSK DID identifiers from private keys
• Use it with a uPort ethr-did compatible interface

Usage

Factory implementation for RSK DID using ethr-did and private keys.

Get an RSK DID using a private key:

import { rskDIDFromPrivateKey } from '@rsksmart/rif-id-ethr-did'

const privateKey = 'c9000722b8ead4ad9d7ea7ef49f2f3c1d82110238822b7191152fbc4849e1891'
const rskDID = rskDIDFromPrivateKey()(privateKey)
rskDID.did
// did:ethr:0x8f4438b78c56B48d9f47c6Ca1be9B69B6fAF9dDa

Use a it with a custom provider:

import Web3 from 'web3'
import { rskDIDFromPrivateKey } from '@rsksmart/rif-id-ethr-did'

let rskDIDFactory

const rpcUrl = 'http://localhost:4444'
rskDIDFactory = rskDIDFromPrivateKey({ rpcUrl })

const web3 = new Web3(rpcUrl)
rskDIDFactory = rskDIDFromPrivateKey({ web3 })

const provider = web3.currentProvider
rskDIDFactory = rskDIDFromPrivateKey({ provider })

Todo

• Use ethr:rsk method

Extend

• Support address recovery using other signers than private keys

Test

From base repo directory run npm test or any of the described test script variants.
