All Implemented Interfaces:

Closeable, AutoCloseable, BinaryManager

public class XORBinaryManager
extends LocalBinaryManager

A simple binary manager that "hides" binaries on the filesystem by scrambling them on write and unscrambling them on read using XOR.

The BinaryManagerDescriptor holds a key that can be used to drive the scrambling/unscrambling.

This is to prevent casual reading of the files, but of course the algorithm and key for scrambling are available on the system as well, so this not a secure store.
