What is Hypervault?

  • Hypervault is a file encryption app meant to provide data-at-rest encryption.
  • Hypervault is entirely contained in a single .html file. As such, you can save the Hypervault page, and you will have a complete working copy of Hypervault which you can run offline.
  • Hypervault outputs another single .html file which contains both the encrypted file data, and a copy of itself.

What Hypervault is NOT?

  • Hypervault does NOT provide data-in-transit security. So if you want to transfer a Hypervault, make sure you transfer it over a secured mechanism (like SSL-encrypted email).

Supported browsers?

  • It seems to work in most modern desktop browsers
  • iOS support is coming soon
  • Android is not yet tested

How do I use Hypervault?

  1. Drag files you want to encrypt into it
  2. Choose a password with which to lock the hypervault (encrypt the files).
  3. Click "Lock vault"
  4. A "locked hypervault" will download to your computer containing your encrypted file data. This can be stored

What is a locked vault?

  • A locked vault is a self-contained HTML file which contains both a copy of the Hypervault software and your encrypted file data.
  • You can simply open a locked vault in a browser and enter your password to decrypt and recover your files.

What's awesome about Hypervault?

  • Secure
    • Hypervault uses the Triplesec library, which uses 3 strong encryption algorithms (AES, Salsa20, and Blowfish), so you can rest assured that your data is safe, even if a couple of the ciphers are compromised.
    • Since Hypervault runs in a browser (which is sandboxed), you never have to worry that it doing anything nefarious on your computer.
    • Zero-knowledge: Hypervault encryption is all client-side, so even if Hypervault's servers are compromised, your data is still safe.
  • Easy
    • No installations necessary, just run in the browser.
  • Offline
    • Since Hypervault is a self-contained HTML file, you save it to your desktop and run it offline.
  • Always usable
    • Since Hypervault packages itself with your encrypted data (in the form of a "locked_vault.html" file, you can always decrypt your data, even if Hypervault goes away.
