The sender enabled client-side encryption for this file. To decrypt and download it in the browser, please open this link using the Chrome desktop browser.
We're currently building the PhotonFile desktop and mobile apps, so you won't need a specific browser in the future.
As a stopgap, we will soon be releasing a thin desktop client for uploading and downloading that will also support the client encryption feature. We will update this notice and the website when that is available.
This feature is too important to have held up waiting for the full desktop application to be finished. Thank you for your understanding!
