Hands on with Boxcryptor, the Cloud Encryptor

Boxcryptor is a file encryption tool works with cloud storage services. Boxcryptor can encrypt files stored on cloud or local drive.

While all of us use cloud storage to enjoy its wider accessibility, at the same time it’s been a matter or privacy and security concern. Cloud services can be exposed to breach risks. If you encrypt your files before uploading them, and hold the decryption key, then your files could not be read even if it goes to a second party. So, encryption increases the privacy significantly. And Boxcryptor is a popular tool to assist you in this way.

To use Boxcryptor, you need to download it first. Get the appropriate software for your device from here. After installing the app, open Boxcryptor. I used Windows version on my computer. Boxcryptor is available for Windows (mobile & PC), Mac, iOS, Android and Blackberry. It also offers a Chrome browser extension. On Windows, the launching window is like this.

For an example, if I want to encrypt my Dropbox file with Boxcryptor, at first I need to run Boxcryptor app and enter into its virtual drive found in my computer hard drive.  Alternatively, the virtual drive can be opened by double clicking the Boxcryptor system tray icon.

After opening the virtual drive, I can see my Dropbox folder inside it, because it is listed in my Boxcryptor app. Opening this Dropbox folder will show the files stored in my Dropbox cloud storage. Now I need to right click on the file which I want to encrypt and hover the mouse on ‘Boxcryptor’ option. Then it shows ‘Encrypt’ button.

Clicking on the ‘Encrypt’ option will encrypt the target file. Once the encryption gets completed, the encrypted file’s name font color becomes Green.

The encrypted files can be accessed easily from the Boxcryptor virtual drive’s cloud home folder (e.g. Dropbox). But it can’t be opened from the Dropbox native drive. There you will see the file with an extra ‘.bc’ extension.

If you want to encrypt multiple files, put them inside a folder and encrypt the entire folder at once. All of the files inside that target folder will be encrypted.

The encrypted folder’s name will be modified. If you encrypt a folder named as ‘New’, after encryption, the folder name will be ‘New_encrypted’. Boxcryptor will try to delete the original file (named as ‘New’ used in this example). If it cannot delete the folder, the app will notify you.

If you put any file inside the encrypted folder, the newer files will be encrypted automatically. To decrypt any file or folder, just right click on them and select ‘Decrypt’ option.

Managing Permission

Boxcryptor lets you share your encrypted files with your friends. To use this ‘Permission’ feature, the other user will also need to be registered with Boxcryptor.

A free plan user can add only one location. That means you can encrypt only one cloud storage’s files with Boxcryptor free version. To enable more than one locations, you need to upgrade first. Adding normal folders inside the computer is also possible. In that case, the encrypted files will exist offline inside your PC.

Opt-in the update checking box to get the latest Boxcryptor. Filename encryption is a Pro feature. So you need a paid plan to use this option.

This is my hands on story with Boxcryptor. It’s time to see the pros and cons.


  • Boxcryptor enhances cloud security and privacy with local encryption and sync.
  • The client app is available on a number of platforms.
  • Boxcryptor PC app is seamless and user friendly.


  • Boxcryptor has no password recovery option. So if you forget your password, you will lose your encrypted files.
  • The app’s special context menu works only within its virtual drive. It would be great if the menu could work from any folder (e.g. Send to Boxcryptor etc.)

The Bottom Line

Thought Boxcryptor offers some limited features in its free version, yet the app can serve your core purpose. If you need its advanced features, upgrade to a pro package!
