Someone sent you a Sealed share.

Open it in four steps

1. Install Sealed. Sealed is free to download, and Sealed Pro is an optional in-app purchase. Sealed needs iOS 17.0 or later. When you first open Sealed it takes you through a few screens, asks you to make a passcode, and shows you your recovery key.
2. Open the file. Sealed registers itself as the app that opens .bbvshare files. Tap the file, and if iOS asks which app should open it, choose Sealed.
3. Add it to your vault. To open a share you unlock your vault, enter the passphrase, and the item is added to your vault.
4. If it doesn’t open, check the passphrase with the sender. A wrong passphrase, or a damaged file, shows an error and adds nothing to the vault.

What a share is

You can send someone an encrypted copy of an item that opens in Sealed with a passphrase you choose, and creating one is part of Sealed Pro.

A share is locked with a key made from its passphrase by PBKDF2-HMAC-SHA256 at 600,000 iterations, then encrypted the same way as the vault. If a share’s passphrase is lost, the share cannot be opened, and we cannot open it for you.

What Sealed enforces, and where

A share file holds the item’s name and type and its encrypted contents. The free-plan rules are applied by the Sealed app when it opens the file.

Opening a share you received is free, but on the free plan Sealed adds photos only, and only while the vault has room.
