How do I encrypt and decrypt a common doc file on windows

[csdjohnson2]

"According to Apple documentation and other documentation I have read about on disk lock on an iOS device, it seems that in order to take advantage of the advanced encryption of the device the user must have a passcode enabled so that when you use the NSDataWritingFileProtectionComplete attribute it will encrypt.

What if the user does not have a passcode set but I still want to ensure the files are encrypted? What options are there for this scenario and how to lock a file?"


After you install the program, you can create a "New Volume," which is the space where you'll be storing the files you wish to send. Anything you put in the volume will be encrypted. You will set a password for the volume, and then "mount" the volume. Mounting the volume basically means you're making it available to put stuff into it, and unmounting will lock the volume from any changes.

What Is Encryption?


But before we get ahead of ourselves, let's take a quick look into what encryption is and how it works. Imagine you are going to send a postcard in the mail. You go to your nearest mailbox and drop the postcard into the slot. What many of us forget is that anyone who handles the postcard on the way to its destination will be able to read exactly what you wrote. This is similar to what happens when your data is sent over an unsecure connection—anyone who intercepts the message has the ability to read it.
