Is there anyway to like encrypt the url, I have a copy of a file that is stored somewhere else (var linkoffile = url where that file is saved) , and when a user requested for that file, I will make a copy of that url in another collection in mongodb and it has an expiration time , a time duration where that file will be available for that user, after that time , the copy of that url will be removed for that user (here I used TTL Indexes of mongodb). But Im thinking that since the url of that file is exposed in the frontend or in the client side, even if you removed the url copy in the mongodb , any user that already copied the url before it expired can still access the document, so im thinking of like encrypting the url so that user will not now where that file is coming.

Is there any way to achieve this? or is there any other solution that can also achieve what im planning to do?
