EFS-Tools is a set of user space tools and libraries that enable encrypted file system support in Android OS. The project relies on ecryptfs Linux kernel module and aims to provide better methods for protecting end user data.

Since Android is build on top of the Linux kernel, EFS-Tools library and executables can be easily ported to any Android device independently of the AOSP version. However, there is a small demo of EFS-Tools library, which requires graphicall interface. For this to work you must download and build the Android 4.4_r1.2 (kitkat) tree.
