shashank-kodiya/SecureShare ? reverse-engineered prompt

Build me a secure file sharing app where people can sign up, log in, upload files, and share them with a private link. I want the link to support an expiry time, a password if needed, and the option to only let specific email addresses open it. It should also be possible to set a download limit, including a one time link, and to revoke access later from a shared history page.

Make it feel like a real product with a clean dashboard, file list, sharing history, search and filters, and a notifications area for when a link is opened or a file is downloaded. I also want download tracking so I can see who accessed a file, when, and from where. Please keep files encrypted at rest, and make the sharing flow work end to end with MongoDB, Express, React, and Node. If you need to check current docs for anything, go ahead and look them up online.
