Encrypted Preferences in Java

Listing 1: A simple test program. It stores a value in the preferences database in the root node for its package ("pkg"), and another value in a subnode of the root node.

// $Id$

package pkg;

import java.util.prefs.*;

public class Test
{
  static public void main( String args[] ) throws Exception {
    Preferences root = Preferences.userNodeForPackage( Test.class );

    root.put( "not", "encrypted" );

    Preferences subnode = root.node( "subnode" );
    subnode.put( "also not", "encrypted" );

    root.exportSubtree( System.out );
  }
}
