Data Stash is an award-winning clever little security tool that allows you to hide sensitive data files within other files. Select a large bitmap or database file (or any file you'd like to use) as a receptacle, then add the data files you'd like to hide, via an easy drag and drop mechanism. The receptacle file remains fully functional. Password protection is also provided, using Blowfish encryption. This is useful if you wish to keep out certain files from prying eyes, under the guise of a normal file. For example you can hide sensitive document files into a bitmap file, and retrieve them later. Opening the bitmap file would only show the image of the bitmap, and not the files that are stored in it. You can hide files into .exe, .com, .mpg, and so on.
