React Native

import { BinData, Http, 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.

  const secrets = new Secrets();

  // On Windows, this is the Windows Credentials Manager
  // On MacOS/iOS, it is the Apple Keychain
  secrets.location = 'local_manager';

  // Specify the name of the secret.
  // service and username are required.
  // appName and domain are optional.
  // Note: The values are arbitrary and can be anything you want.
  const json = new JsonObject();
  json.updateString('appName', 'Test2');
  json.updateString('service', 'Custom');
  json.updateString('domain', 'Ocean');
  json.updateString('username', 'Starfish20');

  // The purpose of this example is to show how arbitrary binary data
  // can be stored as a secret.

  // We'll use a small JPG image that is approximately 2KB in size.
  // You can test using this same JPG at this URL:
  const url = 'https://chilkatdownload.com/sample_data/starfish20.jpg';
  const http = new Http();
  const bd = new BinData();
  try {
    await http.downloadBdAsync(url, bd);
  } catch {
    console.log(http.lastErrorText);
    return;
  }

  // Create or update the binary secret.
  try {
    await secrets.updateSecretBdAsync(json, bd);
  } catch {
    console.log(secrets.lastErrorText);
    return;
  }

  console.log('Success.');
