How can data received from a form be securely transmitted to a remote PHP script without exposing sensitive information like passwords?

When transmitting data from a form to a remote PHP script, sensitive information like passwords should be encrypted before sending it over the network. One way to achieve this is by using HTTPS to ensure secure communication between the client and server. Additionally, the PHP script should decrypt the encrypted data upon receiving it to access the original information securely. 

// Encrypt sensitive data before sending it
$encryptedPassword = openssl_encrypt($password, 'AES-256-CBC', 'secret_key', 0, '16_character_iv');

// Send encrypted data to remote PHP script using HTTPS

// Decrypt the encrypted data in the remote PHP script
$decryptedPassword = openssl_decrypt($encryptedPassword, 'AES-256-CBC', 'secret_key', 0, '16_character_iv');
