Create Identity Wallet for Isabella


How to Create Identity Wallet for Isabella at MagnetoCorp?



Once Isabella gets a copy of the private key and the certificate that represents her identity,, on the PaperNet, she needs to put them in a local wallet.

Whenever Isabella runs an application, it will open the wallet and use her identify to initialize the connection gateway.

1. View the addToWallet.js script that copies private key and certificate into wallet:

(isabella)$ cd ~/hyperledger-binaries/fabric-samples
(isabella)$ cd commercial-paper/organization/magnetocorp/application

(isabella)$ addToWallet.js 
/* SPDX-License-Identifier: Apache-2.0
'use strict';

// Bring key classes into scope, most importantly Fabric SDK network class
const fs = require('fs');
const { FileSystemWallet, X509WalletMixin } = require('fabric-network');
const path = require('path');

const fixtures = path.resolve(__dirname, '../../../../basic-network');

// A wallet stores a collection of identities
const wallet = new FileSystemWallet('../identity/user/isabella/wallet');

async function main() {
    // Main try/catch block
    try {
        // Identity to credentials to be stored in the wallet
        const credPath = path.join(fixtures, '/crypto-config/peerOrganizations/');
        const cert = fs.readFileSync(path.join(credPath, '/msp/signcerts/')).toString();
        const key = fs.readFileSync(path.join(credPath, '/msp/keystore/c75bd6911aca808941c3557ee7c97e90f3952e379497dc55eb903f31b50abc83_sk')).toString();

        // Load credentials into wallet
        const identityLabel = '';
        const identity = X509WalletMixin.createIdentity('Org1MSP', cert, key);

        await wallet.import(identityLabel, identity);

    } catch (error) {
        console.log(`Error adding to wallet. ${error}`);

main().then(() => {
}).catch((e) => {

2. Run the addToWallet.js script:

(isabella)$ node addToWallet.js

3. Verify wallet:

(isabella)$ ls ../identity/user/isabella/wallet/
