     UPDATE: Fixed a few minor bugs, and added the ability to import any changes the user may have made to a file back into the vault. UPDATE: I have updated the code to implement AES encryption (John Korejwa), and Secure Document Shredder(Steppenwolfe). Fixed a major bug that I was unaware of until I did the update. All file types should be launchable now from within the program. This code demonstrates how to use alternate data streams (ADS) to store programs, files, etc, within another file. There are three projects included in the zip. One is used to View the VaultFiles, one is a blank VaultFile, and the other is used to cleanup tempfiles created when opening a file. Compile all three to the same directory. Launch either FileVaultViewer or VaultFile and the rest should be explained as you go. I have taken extra care to thoroughly comment the code so it should be understandable by coders of any experience level. (Just make sure you understand Alternate Data Streams first.) Feedback would be much appreciated. Much of the information used to create this was obtained from the site http://www.infosecwriters.com/texts.php?op=display&id=53 Also, I used Ion Alex Ionescu's project (located at http://www.planet-source-code.com/vb/scripts/ShowCode.asp?txtCodeId=47299&lngWId=1) for debugging purposes.

Note: Due to the size or complexity of this submission, the author has submitted it as a .zip file to shorten your download time. Afterdownloading it, you will need a program like Winzip to decompress it.Virus note:All files are scanned once-a-day by Planet Source Code for viruses, but new viruses come out every day, so no prevention program can catch 100% of them. For your own safety, please:
  1. Re-scan downloaded files using your personal virus checker before using it.
  2. NEVER, EVER run compiled files (.exe's, .ocx's, .dll's etc.)--only run source code.
  3. Scan the source code with Minnow's Project Scanner

If you don't have a virus scanner, you can get one at many places on the net including:McAfee.com
