One time download liks in php?
I am seeking for a solution for security on a link.
I would like to let the user to be able to click and get to the destinated url, but they won’t be able to read the link from the source code, or maybe to generate a time limited url each time the user lands on the page, so each time the user logs in they will see a different url and would not be able to reuse the old url.
I am not really familiar with php, but I have been doing some research on it as I am seeking the ways to keep my links secure.
I think you could generate the temporary keys to send with the URL, and when user lands on the page, the temporary key should be removed, then this current URL can’t accessed again. You will have to generate unique keys for each user.
