Encryption in Transit and At Rest

19 05 2017

There is an app for that.

It’s Boxcryptor by the German Secomba GmbH and it’s easy to use with a perfect design. Nothing is saved on Secomba’s servers without being encrypted by the user’s password, a zero-knowledge relationship between the user and the company behind Boxcryptor.


Here’s a short guide for backup freaks enabling them to even access their sensitive information in the worst case (iPhone died or was stolen). The good news is that they can even do it with their 💯$ Windows 10 backup phone.

Let’s get ready to rumble …

If a note contains sensitive information it can be locked with iOS’s built-in encryption capabilities. As an option it’s either stored locally on the iOS device or on iCloud.

It’s intended to

  • store an encrypted backup on a further cloud storage like Dropbox, Box, OneDrive, Google Drive, etc
  • ensure access to encrypted files from a device running on a different OS, e.g. a mobile phone running on Windows 10

Here is the workaround to transfer files from Apple Notes on an iPhone to Dropbox as a strongly encrypted PDF.

  1. Write a note.
  2. Tap on the Action Menu (top right).
  3. Choose PRINT.
  4. In PRINT PREVIEW force press on page 1.
  5. Tap on the Action Menu (bottom left).
  6. Choose BOXCRYPTOR.
  7. In BOXCRYPTOR choose UPLOAD.

Note …
A zero-knowledge service provider will always store any private and sensitive information in an encrypted form protected by the user’s password – which is never transferred to the provider. Passwords, password keys, and file keys never leave the users’ devices and are never transferred anywhere or to anyone.

Handle with care! Zero-knowledge means that Secomba cannot help you if you forgot your password. You’ll lose access to all encrypted files.

Benefits …

Your are safe and so you are. If you buy a new device you mustn’t take care of the OS. Boxcryptor runs on Windows, Windows Mobile, macOS, Android, iOS, Blackberry, and Chrome. 28 clouds are supported including Apple iCloud. You can share files with non-Boxcryptor users (Dropbox, OneDrive, Google Drive only as of May 2017).
