TOTP based file-sharing

A webserver allowing to share files with dynamic URLs.

The files are associated with a TOTP token allowing people that knows this token to guess the URL.

The advantage here is that the URL is only working for a small amount of time.

As soon as your connection is secure against man-in-the-middle attacks, you can consider that it’s a protection against an history replaying.
