How can PHP be used to securely handle encrypted data from a database, specifically SQLite, and pass it as parameters?

To securely handle encrypted data from an SQLite database in PHP, you can use encryption functions like OpenSSL to encrypt and decrypt the data before storing and retrieving it from the database. When passing encrypted data as parameters, make sure to decrypt it before using it in your application to ensure the data remains secure. 

<?php
// Encrypt data before storing in the database
$encryption_key = "YourEncryptionKey";
$data_to_encrypt = "Sensitive data";
$encrypted_data = openssl_encrypt($data_to_encrypt, 'AES-256-CBC', $encryption_key, 0, 'YourIV');

// Store the encrypted data in SQLite database

// Retrieve encrypted data from SQLite database
// Decrypt data before using it as parameters
$decrypted_data = openssl_decrypt($encrypted_data, 'AES-256-CBC', $encryption_key, 0, 'YourIV');

// Use the decrypted data as needed
echo $decrypted_data;
?>
