React Native

import { BinData, JsonObject, Secrets } from '@chilkat/react-native'

async function chilkatExample() {
  // This example requires the Chilkat API to have been previously unlocked.
  // See Global Unlock Sample for sample code.

  // The bootstrap secret will contain the following information:

  // Azure Tenant ID
  // Azure Client ID
  // Azure Client Secret

  // See following examples for setting up a bootstrap secret in memory, 
  // or in the local manager (Windows Credentials Manager or Apple Keychain)
  // Setup Bootstrap Secret in Local Manager
  // Setup Bootstrap Secret in Memory
  const bootstrap = new Secrets();

  // Set the location of the bootstrap secret.
  // Can be "local_manager" or "memory", depending on how you setup the bootstrap secret.
  // ---------------------------------------------------------------------------------------------
  // If your operating system is NOT Windows or MacOS/iOS, then change "local_manager" to "memory"
  // You can also, if desired, use "memory" on Windows and MacOS/iOS if your bootstrap secret was previously setup in memory.
  // ---------------------------------------------------------------------------------------------
  bootstrap.location = 'local_manager';

  // Specify the bootstrap secret to be used.
  const bsId = new JsonObject();
  bsId.updateString('appName', 'azure_bs');
  bsId.updateString('service', 'Example');
  bsId.updateString('username', 'Joe');

  // ----------------------------------------------------
  const secrets = new Secrets();

  secrets.location = 'azure_key_vault';
  try {
    secrets.setBootstrapSecret(bsId, bootstrap);
  } catch {
    console.log(secrets.lastErrorText);
    return;
  }

  // Specify the secret to be fetched.
  const json = new JsonObject();
  json.updateString('appName', 'Test2');
  json.updateString('service', 'Custom');
  json.updateString('domain', 'Ocean');
  json.updateString('username', 'Starfish');

  // For Azure Key Vault, we also need to specify the name of the vault where the secret is located.
  // Replace "kvChilkat" with the name of your key vault.
  json.updateString('vaultName', 'kvChilkat');

  // Get the binary secret data.
  const bd = new BinData();
  try {
    await secrets.getSecretBdAsync(json, bd);
  } catch {
    console.log(secrets.lastErrorText);
    return;
  }

  // For our testing, the binary secret was a JPG image..
  bd.writeFile('c:/temp/qa_output/starfish.jpg');

  console.log('Success.');
