 * UTILITY SCRIPT: Generate a Client Secret using your TLS certificates.
 * 
 * Run this ONCE when setting up the project or if you lose your secret.
 * 
 * Requirements:
 * 1. You have the `client_id` (Found in Developer Portal -> App Settings URL or Overview).
 * 2. You have the TLS certificates (.pem/.key) authorized by the bank.
 *    - Prod: You sent CSR to bank, they enabled integration and sent .cer back.
 *    - Sandbox: You downloaded them from the email/portal.
