Thanks.
I am not aware of Java API's which let you protect files with a password.

Why dont you use the Serializable interface of Java and serialize the private key ? See this tech tip from Sun.

NAME
ajdoc -- generate HTML API documentation, including crosscutting structure SYNOPSIS
ajdoc [ -bootclasspath classpathlist ] [ -classpath classpathlist ] [-d path] [-help] [-package] [-pro- tected] [-private] [-public] [-overview overviewFile] [ -sourcepath sourcepathlist ] [-verbose] [-version] [source- files... | packages... | @file... | -argfile file... ] [ ajc options ] Description ajdoc renders HTML documentation for AspectJ constructs as well as the Java constructs that javadoc renders. In addition ajdoc displays the crosscutting nature in the form of links. That means, for example, that you can see everything affecting a method when reading the doc- umentation for the method. To run ajdoc, use one of the scripts in the AspectJ bin directory. The ajdoc implementation builds on Sun's javadoc command line tool, and you use it in the same way with many of the same options (javadoc options are not documented here; for more information on javadoc usage, see the Javadoc homepage http://java.sun.com/j2se/javadoc/) . As with ajc (but unlike javadoc), you pass ajdoc all your aspect source files and any files containing types affected by the aspects; it's often easiest to just pass all the .java and .aj files in your system. Unlike ajc, ajdoc will try to find package sources using the speci- fied sourcepath if you list packages on the command line. To provide an argfile listing the source files, you can use use the same argfile (@filename) conventions as with ajc. For example, the following documents all the source files listed in argfile.lst, sending the output to the docDir output directory. ajdoc -d docDir @argfile.lst See the ajc documentation for details on the text file format. ajdoc honours ajc options. See the ajc documentation for details on these options. ajdoc currently requires the tools.jar from J2SE 1.3 to be on the classpath. Normally the scripts set this up, assuming that your JAVA_HOME variable points to an appropriate installation of Java. You may need to provide this jar when using a different version of Java or a JRE. Examples Documenting Spacewar o Change into the examples directory. o Type mkdir doc destination directory for the documentation. o Type ajdoc -private -d doc spacewar coordination o (Use -private to get all members, since may of the interesting ones in spacewar are not public.) o Type ajdoc -private -d doc @spacewar/demo.lst to use the argfile associated with Spacewar. o To view the documentation, open the file index.html in the doc directory using a web browser. ajdoc(1)
