/**
 * @name Secure Storage
 * @description
 * This plugin gets, sets and removes key,value pairs from a device's secure storage.
 *
 * Requires Cordova plugin: `cordova-plugin-secure-storage`. For more info, please see the [Cordova Secure Storage docs](https://github.com/Crypho/cordova-plugin-secure-storage).
 *
 * The browser platform is supported as a mock only. Key/values are stored unencrypted in localStorage.
 * @usage
 *
 * ```typescript
 * import { SecureStorage, SecureStorageObject } from '@awesome-cordova-plugins/secure-storage/ngx';
 *
 * constructor(private secureStorage: SecureStorage) { }
 *
 * ...
 *
 * this.secureStorage.create('my_store_name')
 *   .then((storage: SecureStorageObject) => {
 *
 *      storage.get('key')
 *        .then(
 *          data => console.log(data),
 *          error => console.log(error)
 *      );
 *
 *      storage.set('key', 'value')
 *        .then(
 *         data => console.log(data),
 *          error => console.log(error)
 *      );
 *
 *      storage.remove('key')
 *      .then(
 *          data => console.log(data),
 *          error => console.log(error)
 *      );
 *
 *   });
