What are the potential pitfalls of storing sensitive data in a file within a password-protected directory?

Storing sensitive data in a file within a password-protected directory can still be risky as the password may be compromised, leading to unauthorized access to the data. To mitigate this risk, it is recommended to encrypt the sensitive data before storing it in the file. This way, even if the password is compromised, the data will still be secure. 

<?php
// Encrypt sensitive data before storing in a file
$sensitiveData = "This is sensitive data";
$key = "my_secret_key";
$encryptedData = openssl_encrypt($sensitiveData, 'AES-256-CBC', $key, 0, 'my_secret_iv');

// Store the encrypted data in a file within a password-protected directory
file_put_contents('/path/to/password-protected-directory/sensitive_data.txt', $encryptedData);
?>
