REST Basic Auth with Secure Strings

Demonstrates how to do REST Basic authentication using secure strings.

This example requires Chilkat v9.5.0.71 or greater.

// Important: Don't forget to include the call to System.loadLibrary
// as shown at the bottom of this code sample.

  // Called when the activity is first created.

    boolean success = false;

    //  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_login": "mCrOmA7mBA7Au9RuJGb9hw==",
    //    "http_password": "jJtiI9TgErTTpqBz9JtHBw=="

    crypt.put_CryptAlgorithm("aes");

    CkSecureString ssLogin = new CkSecureString();
    CkSecureString ssPassword = new CkSecureString();

    //  Decrypt to the secure string.  (the strings will still held in memory encrypted, but are now encrypted using
    //  a randomly generated session key.)
    crypt.DecryptSecureENC(json.stringOf("http_login"),ssLogin);
    crypt.DecryptSecureENC(json.stringOf("http_password"),ssPassword);
