/**
 * Simple Authorization using JWT with Shared Secret + MLE (Message Level Encryption).
 *
 * <p>This sample demonstrates the primary benefit of migrating from HTTP Signature
 * to JWT with Shared Secret: <b>MLE support</b>. MLE encrypts the request payload
 * at the application level before it is sent over the network, providing an
 * additional layer of security beyond TLS.</p>
 *
 * <h2>Key Difference from HTTP Signature</h2>
 * <p>HTTP Signature does not support MLE. By switching to JWT with Shared Secret,
 * you gain MLE capability using the <b>same credentials</b> you already have.</p>
 *
 * <h2>MLE Certificate</h2>
 * <p>When using {@code jwtKeyType=SHARED_SECRET}, the MLE public certificate must
 * be provided via the {@code mleForRequestPublicCertPath} property. Download it from
 * the CyberSource Business Center:</p>
 * <ul>
 *   <li>Test: <a href="https://businesscentertest.cybersource.com/ebc2">businesscentertest.cybersource.com/ebc2</a></li>
 *   <li>Production: <a href="https://businesscenter.cybersource.com/ebc2">businesscenter.cybersource.com/ebc2</a></li>
 * </ul>
 *
 * <p>See {@link Data.JwtSharedSecretConfiguration#getMerchantDetailsWithMLE()} for the
 * full configuration.</p>
