Hi All,

I need to make an application where in from a servlet a file is to be created and stored on local pc, which contains some important info..

Now What I want is that When I create a file it should be password protected so that when anybody tries to open it directly (i.e. by double clicking on the file) it would not be accessible without password..

Is it Possible??

If not, can I have such directory..
so as to implement "vault" like mechanism.

Any ideas how you were going to do that with a Servlet? Servlets run on the server, they can't interact with the file system on the client.


Now What I want is that When I create a file it should be password protected so that when anybody tries to open it directly (i.e. by double clicking on the file) it would not be accessible without password..


Why would you allow download of a file the client (potentially) cannot open?

The best thing to do would to not allow download except for people that should see the file in the first place. Failing that, perhaps a password-protected PDF might work?

In any case, not really a Servlets question.

I am going to create that file on Server only, I want that no user of Server can access it without password..

No client side interaction or downloading is going to be done.

As Bear mentioned a password protected PDF would probably work for you.

You can also password protect zip files.
Unfortunately, Java (last I checked) can't create password protected zip files so you would need to look for a third party library to do this.

Local PC == client
