How can dynamic and static salts be securely passed to the authentication process in a Zend Framework application?

Dynamic and static salts can be securely passed to the authentication process in a Zend Framework application by storing them in a secure location, such as a configuration file or environment variables, and retrieving them when needed during the authentication process. This ensures that the salts are not hard-coded in the codebase, reducing the risk of exposure. 

// Retrieve dynamic and static salts from a configuration file
$config = include 'config.php';
$dynamicSalt = $config['dynamic_salt'];
$staticSalt = $config['static_salt'];

// Use the salts in the authentication process
$hashedPassword = hash('sha256', $dynamicSalt . $password . $staticSalt);
