Encrypt Dropbox Files - BoxCryptor

Maintaining Dropbox Convenience with Enhanced Security

While Dropbox offers a user-friendly experience, its past security performance hasn't always inspired confidence.

Although we've explored various encrypted alternatives to Dropbox previously, its ease of use remains a significant draw for many users.

The desire for robust encryption often clashes with the simplicity of Dropbox; however, BoxCryptor provides a solution for those unwilling to compromise.

How BoxCryptor Works

BoxCryptor functions as an encryption layer applied directly to your existing Dropbox account, allowing you to retain the familiar interface and accessibility.

Essentially, it automates the process of file encryption, mimicking the security of manual encryption without the associated complexities.

Cross-Platform Accessibility

A key advantage of BoxCryptor is its broad platform support.

  • It is compatible with Windows, Mac, and Linux operating systems.
  • Mobile access is enabled through applications for iOS and Android devices.

This widespread compatibility ensures you can securely access your encrypted data from a wide range of devices and locations.

Beyond Dropbox: Versatile Cloud Compatibility

The utility of BoxCryptor extends beyond just Dropbox.

It can also be utilized with other popular cloud storage platforms, such as Microsoft’s SkyDrive, offering a consistent encryption solution across multiple services.

This flexibility makes BoxCryptor a valuable tool for individuals who utilize a variety of cloud storage options.

Acquiring BoxCryptor

The complimentary version of BoxCryptor is available for download directly from the official BoxCryptor website.

This free edition of BoxCryptor allows for the encryption of up to 2 GB of data. This capacity aligns perfectly with the initial storage allocation provided to new Dropbox users.

Encryption Limits and Practical Usage

Should your Dropbox storage exceed 2 GB, encrypting all files would necessitate a paid subscription. However, a more practical approach involves selectively encrypting only those files containing sensitive information.

Unimportant files can remain unencrypted within the primary Dropbox directory, optimizing both security and cost-effectiveness.

BoxCryptor provides a focused security solution, allowing users to prioritize the protection of their most valuable data.

Initial Configuration

Upon installation of BoxCryptor, users are guided through the process of establishing a new encrypted folder.

The 'Browse' function allows you to designate a specific location for these protected files. For those utilizing Dropbox with standard configurations, directing BoxCryptor to a folder within the “C:\Users\[Name]\Dropbox” directory is recommended.

A new, virtual drive is generated by BoxCryptor, presenting your encrypted files in a readily accessible, unencrypted state. By default, drive Z: is assigned, though this drive letter can be altered to suit your preferences.

The creation of a strong password represents the most critical step in the BoxCryptor setup. Your files are secured through encryption utilizing the password you define at this stage.

It is strongly advised by BoxCryptor to record this password and maintain it in a secure, easily retrievable location. Loss of this password results in permanent inaccessibility to your encrypted files.

Furthermore, BoxCryptor suggests backing up its configuration file, which resides within the BoxCryptor directory you previously selected. This backup is essential for recovery should the primary configuration file become corrupted or deleted.

Without this backup, data loss is inevitable and irreversible.

Maintaining this configuration file backup ensures continued access to your encrypted data.

Employing BoxCryptor

After the initial configuration of BoxCryptor is complete, its operation is remarkably straightforward. The BoxCryptor drive will be readily accessible within your Computer window.

To secure your data, simply transfer any confidential files you wish to encrypt into this designated BoxCryptor drive for cloud storage.

Upon adding files to the drive, BoxCryptor automatically encrypts them. The resulting encrypted files are then placed within a folder located inside your existing Dropbox directory.

The synchronization process with Dropbox proceeds as usual. From Dropbox’s perspective, these are standard files requiring no special handling.

To gain access to your encrypted files on a different machine, install BoxCryptor and choose the “Open an Existing Folder” function.

Mobile App

Certain restrictions apply to the complimentary mobile app version; for instance, file reading is the only supported function, and navigation is limited to a maximum of two directory levels.

However, it provides a convenient method for accessing your encrypted Dropbox files while traveling.

App Functionality

BoxCryptor’s mobile application operates independently and does not necessitate the presence of the Dropbox application on your device.

Upon installation, you will be guided through the process of logging into your Dropbox account.

Accessing Encrypted Files

Following successful login, you can choose your encrypted BoxCryptor folder.

The application will then request the password you initially established for encryption.

Password Verification and File Display

Inputting the correct password will reveal the decrypted versions of your files.

Conversely, if you were using the standard Dropbox mobile app, you would only encounter the obfuscated, encrypted file formats.

Final Thoughts

In essence, BoxCryptor mirrors the straightforward approach of Dropbox, avoiding a complex interface laden with numerous settings. It functions as an ideal complement to Dropbox's functionality.

For those utilizing a Linux operating system, EncFS presents an alternative method for encrypting files stored within Dropbox. While EncFS circumvents the 2 GB file size restriction, BoxCryptor generally offers a more intuitive user experience.
