Can the decryption process be handled effectively with the exec function in PHP on Windows systems?

The exec function in PHP on Windows systems may not be the most secure or reliable way to handle decryption processes. It is recommended to use more secure methods, such as PHP's built-in encryption functions or third-party libraries.

// Example of a more secure way to decrypt data using PHP's openssl_decrypt function
$encryptedData = "encrypted_data_here";
$decryptedData = openssl_decrypt($encryptedData, 'AES-256-CBC', 'encryption_key_here', 0, 'iv_here');
echo $decryptedData;
