SpiderOak, a maker of software for secure file syncing, has released an open source application for Android.

We've dubbed SpiderOak "Dropbox for the security obsessive" for several reasons, including the fact that the company promises that it never knows a user's password or encryption keys. This should make it nearly impossible for company employees to access your data, but the downside is that losing your password means losing access to your account.

SpiderOak was a bit difficult to set up when we first looked at it, but last month the company unveiled "SpiderOak Hive." This option adds a folder to your computer's file manager, turning file syncing into a drag-and-drop process much like users get from Dropbox, Google Drive, or SkyDrive. The iOS application was updated to support Hive, and today's Android update brings Hive support as well.

The Android application can be downloaded from Google Play, and its source code is available on GitHub under the Apache License.

"SpiderOak is working on re-implementing its client applications for mobile devices as a central, platform-independent HTML5/Javascript/CSS core with native extensions to fill in the functionality gaps," the company wrote on its GitHub page. "This is intended to replace the current, platform-specific native applications. We see many potential benefits to the HTML5 approach, among them being implementation in a widely used, comprehensible (if we're careful) medium that can be very useful to others."

As for making the app code open source, SpiderOak said it's hoping to encourage collaboration with other developers. The application works on Android 2.3 and newer, but it uses "styling to make the new app match Android 4.0 and above." SpiderOak revealed BlackBerry and Windows Phone clients are in the works as well.
