How is my transfer encrypted with Send?

Every file you send is encrypted before it ever leaves your browser.

When you use Send, your files are encrypted on your device before anything is uploaded. That means:

  • No one (not even Hivenet) can read your file contents

  • Files stay encrypted while stored across the distributed network

  • The only way to decrypt the file is with the unique download link

This is called end-to-end encryption and it’s baked into every transfer by default. You don’t need to turn it on. You can’t turn it off. It’s just how Send works.

What kind of encryption does Send use?

We use AES-256 encryption to secure each chunk of your file. It’s a strong, industry-standard algorithm used for everything from cloud storage to banking systems.

In simple terms: Your file is locked with a key only your link can unlock — and that key is never shared with us.

What if I add a password?

Adding a password gives your transfer an extra layer of encryption. Even if someone gets the download link:

  • They won’t be able to open the file

  • They’ll be prompted to enter the correct password first

  • We never store or recover your password. It’s all handled in the browser

You’ll need to share the password separately (e.g. over chat or in person).

What about metadata?

We don’t collect or store:

  • File names

  • File contents

  • User messages

  • Recipient info (since you share the link yourself)

We only keep temporary logs for performance and security — and only for as long as needed to deliver your file.
