I find myself often having to transfer a random files from another person’s device to mine. Existing file sharing solutions aren’t exactly ideal because they either require me to remember a very long URL (file shares), or requiring me to log in on others’ device (cloud). I’m wondering if there’s a program where anyone can upload files, but can only be viewed and downloaded from the server by authenticated users. I understand it’s not wise to accept files from unauthenticated users, but it would be so damn convenient. If there isn’t one, I suppose that would be my next project.
You may be surprised but a private (self-hosted) torrent tracker is how I did this when I had crappy internet and had to send over a bunch of pictures and video to family.
You can encrypt the data before sending, although it still should be fairly safe, speeds don’t matter much, there’s no storage to pay for or risk leaking.
