What potential challenges arise when trying to manipulate ownCloud calendar entries using PHP due to encryption?

When trying to manipulate ownCloud calendar entries using PHP, one potential challenge that arises due to encryption is that the data stored in the calendar may be encrypted, making it difficult to directly manipulate the entries without decrypting them first. To solve this issue, you would need to decrypt the calendar data before making any changes and then encrypt it again after the modifications are complete. 

// Assume $encryptedData contains the encrypted calendar data
$decryptedData = openssl_decrypt($encryptedData, 'AES-256-CBC', $encryptionKey, 0, $iv);

// Manipulate the decrypted data as needed

$encryptedData = openssl_encrypt($decryptedData, 'AES-256-CBC', $encryptionKey, 0, $iv);
