Demonstrates how to do REST Basic authentication using secure strings.

This example requires Chilkat v9.5.0.71 or greater.

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// Imagine we've previously saved our encrypted login and password within a JSON config file
// that contains this:

//   "http_password": "jJtiI9TgErTTpqBz9JtHBw=="
