Open a protected download

A download of your data that you protected with a passphrase, opened in your browser.

Note: Your file is opened on your device, by this page: it is never uploaded, and nothing about it is sent anywhere. You don’t need to sign in, so a file still opens here after the account it came from is deleted.

Open a file

With the age app

A protected download is an age file (age-encryption.org), so the age app opens it too, without Nya. It runs on macOS, Linux and Windows. In a terminal:

age -d -o nya-data-2026-10-10.json nya-data-2026-10-10.json.age

It asks for the passphrase, then writes the opened file. To install it: brew install age on a Mac with Homebrew, apt install age on Debian or Ubuntu, or winget install --id FiloSottile.age on Windows.

If it doesn’t open

  • Type the passphrase exactly as you set it: capitals, spaces and punctuation count. Nya never keeps it, so nobody can recover a lost one, and nobody can open the file without it.
  • A file that was cut short while it was saved, or changed since, doesn’t open at all rather than opening in part. Download it again.
  • Unlocking the file takes about 256 MB of memory for a few seconds, then room for what it opens. An older phone may stop the page, or say it can’t spare the memory: open the file on a computer instead.
  • Once opened, the file isn’t protected any more, so keep it somewhere safe.
