Overview

The IBM Cloud Key Protect Node.js SDK allows developers to programmatically interact with the following IBM Cloud services:

Key protect Service

Prerequisites

• An IBM Cloud account.

• A Key Protect service instance.

• An IBM Cloud API key that allows the SDK to access your account.

• Node.js version 14 or above.

  This SDK is tested with Node versions 14 and up. The SDK may work on previous versions, but this is not supported officially.

Installation

npm install @ibm-cloud/ibm-key-protect

Authentication

Key Protect uses token-based Identity and Access Management (IAM) authentication. With IAM authentication, you supply an API key that is used to generate an access token.

Authentication for this SDK is accomplished by using IAM authenticators.

To learn more about IAM authenticators and how to use them in your Node.js application, see the IBM Node.js SDK Core documentation.

Using the SDK

Basic usage

• All methods return a Promise that either resolves with the response from the service or rejects with an Error. The response contains the body, the headers, the status code, and the status text.

• Use the serviceUrl parameter to set the endpoint URL that is specific to your Key Protect service instance. The endpoint can be either public or private, for example:

  serviceUrl: 'https://us-south.kms.cloud.ibm.com'
  

  or

  serviceUrl: 'https://private.us-south.kms.cloud.ibm.com'
  

Examples

const KeyProtectV2 = require('@ibm-cloud/ibm-key-protect/ibm-key-protect-api/v2');
const { IamAuthenticator } = require('@ibm-cloud/ibm-key-protect/auth');

// env vars, using external configuration in this example
const envConfigs = {
  apiKey: process.env.IBMCLOUD_API_KEY,
  iamAuthUrl: process.env.IAM_AUTH_URL,
  serviceUrl: process.env.KP_SERVICE_URL,
  bluemixInstance: process.env.KP_INSTANCE_ID,
};

async function keyProtectSdkExample() {
  let response;

  // Create an IAM authenticator.
  const authenticator = new IamAuthenticator({
    apikey: envConfigs.apiKey,
    url: envConfigs.iamAuthUrl,
  });

  // Construct the service client.
  const keyProtectClient = new KeyProtectV2({
    authenticator,
    serviceUrl: envConfigs.serviceUrl,
  });

  // Create a key
  const body = {
    metadata: {
      collectionType: 'application/vnd.ibm.kms.key+json',
      collectionTotal: 1,
    },
    resources: [
      {
        type: 'application/vnd.ibm.kms.key+json',
        name: 'nodejsKey',
        extractable: false,
      },
    ],
  };
  const createParams = Object.assign({}, envConfigs);
  createParams.body = body;
  response = await keyProtectClient.createKey(createParams);
  const keyId = response.result.resources[0].id;
  console.log('Key created, id is: ' + keyId);

  // Get the key
  const getKeyParams = Object.assign({}, envConfigs);
  getKeyParams.id = keyId;
  response = await keyProtectClient.getKey(getKeyParams);
  console.log('Get key result: ');
  console.log(response.result.resources[0]);

  // Get list of keys associated to the instance
  response = await keyProtectClient.getKeys(envConfigs);
  console.log('Get keys result:');
  for(let resource of response.result.resources){
     console.log(resource);
  }

  // Wrap and unwrap key
  const samplePlaintext = 'dGhpcyBpcyBhIGJhc2U2NCBzdHJpbmcK'; // base64 encoded plaintext

  const wrapKeyParams = Object.assign({}, envConfigs);
  wrapKeyParams.id = keyId;
  wrapKeyParams.keyActionWrapBody = {
    plaintext: samplePlaintext,
  };
  response = await keyProtectClient.wrapKey(wrapKeyParams);
  console.log('Wrap key response status: ' + response.status);
  const ciphertextResult = response.result.ciphertext;

  const unwrapKeyParams = Object.assign({}, envConfigs);
  unwrapKeyParams.id = keyId;
  unwrapKeyParams.keyActionUnwrapBody = {
    ciphertext: ciphertextResult, // from wrap key response
  };
  response = await keyProtectClient.unwrapKey(unwrapKeyParams);
  console.log('Key plain text is: ' + response.result.plaintext);   //should be the same as 'samplePlaintext' above

  // Delete key
  const deleteKeyParams = Object.assign({}, envConfigs);
  deleteKeyParams.id = keyId;
  deleteKeyParams.prefer = 'return=representation';
  response = await keyProtectClient.deleteKey(deleteKeyParams);
  console.log('Delete key response status: ' + response.status);
}

Tests

This project includes unit tests test/unit and integration tests test/integration.

The integration tests require the auth.js file with proper configuration values to be added under test/resources, use auth.example.js under the same directory as example to create the auth.js file.

To run the tests:

npm run test
npm run test-unit
npm run test-integration

Questions

If you are having difficulties using this SDK or have a question about the IBM Cloud services, please ask a question at Stack Overflow.

You can also check out the Key Protect documentation and API reference for more information about the service.
