Everybody's got something they want to hide. Whether it's that photo of you with a lampshade on your head that you don't want the kids to see, or the business plan for your next killer startup, it's nice to be able to encrypt files to keep your stuff to yourself. So how do you plan to go about that?
JavaEncryptor is a tool that pretty much tells you everything you need to know in its name. It's a Java app, so it will run on Linux, Mac, Windows, or just about any other system that has a current Java runtime installed. And the "encryptor" part means that you will take your original source file and turn it into encrypted gobbledegook, making it impossible for any mere mortal to see what's in that file. It's got a simple interface—just click the Encrypt button—and you can browse to the file you want to work on, enter a password, and go. While it encrypts your file, it's also compressing it, a handy added bonus.
JavaEncryptor is a free download.
