How does the end-to-end encryption work?

Available in: PRO

With end-to-end encryption (also referred to as “E2E encryption”), your files are fully encrypted in the browser before they are uploaded and are then transmitted in this form to the recipients. A secret key (a kind of password) is generated, which the recipients must specify when downloading in order to decrypt the files.

End-to-end encryption is only available for sending files.

Creating an encrypted transfer

  1. Log in to File Express using your e-mail address and password.
  2. In the transfer form, switch from “Standard” to the “Encrypted” option.

  3. Upload the files or folders you want to send.
  4. Configure the settings for your transfer (availability, download limit, language, etc.).
  5. Click “Create transfer”. 
    → Once the transfer has been created, a confirmation page with the link and the password appears.

  6. Decide whether you want to send the link and password separately or include the password in the link.

    For security reasons, we recommend that you always send the link and password separately. Don’t forget to copy the password on the confirmation page, as it will not be possible to view or change it afterwards.

  7. You can now copy the link and the password, share them via WhatsApp or use File Express directly to send them to the recipients via e-mail.

You will receive an e-mail to confirm the created transfer. You can also track the transfer in your account under “Transfers”.
