Vault

Even we can't open it

Vault drops are end-to-end encrypted. Use them for contracts, IDs, medical records, source code or anything that should only be seen by the person you send it to.

  1. 1

    Your browser makes a key

    A random 256-bit key is created on your device when you choose Vault.

  2. 2

    Files are encrypted before upload

    Each file, its name and its type are encrypted in chunks with AES-256-GCM. We receive only ciphertext.

  3. 3

    The key travels in the link

    It sits after the # in the URL. Browsers never send that part to a server, so it never reaches us.

  4. 4

    The recipient's browser decrypts

    Opening the link decrypts the files locally. Comments on Vault drops are encrypted the same way.

The part after # never reaches our servers. We store ciphertext we can't read.

Security & Vault

Private by default. Unreadable when it matters.

Passcodes, invite-only links, watermarks and expiry come free. Vault drops are end-to-end encrypted with AES-256-GCM in your browser, so not even Slingdrop can open them.

  • Malware scanning on every upload
  • Burn after reading
  • Dynamic watermarks with viewer email
  • Isolated content domain
  • Audit logs for teams
  • GDPR export and deletion

Good to know

  • Anyone with the full link can open the drop, so share it the way you'd share a key. Add a passcode to wrap the key for extra protection.
  • If you lose the link, we can't recover the files. That's the point.
  • Previews are generated in the recipient's browser, so very large files open more slowly than normal drops.
  • AI features, server-side previews and malware scanning don't run on Vault drops, because we can't read them.
  • Vault needs a free account with a verified email.
