A few days back, a reader sent me an email about how to use MicroSoft Private Folder. I made a post about MS Private Folder long time back but didn't mention how to use it.
Recently I found TrueCrypt which is an open source encryption software made 'for experienced users'. Well, I am not very experienced with encryption except that I worked with hashing in PHP recently on a pet project. But TrueCrypt seemed easy and very much intuitive. Here is how I am using it to protect my files from unwanted access.
Download and Install
First things first. Download TrueCrypt from here. You can install TrueCrypt in two diff ways: a complete install and a portable installation. I preferred a portable installation, since that won't be affected even if I mess up with Windows registries (which often happens to me!).
Choose extract when the installation mode dialog box comes up.
Next, select the folder where you want to put the extracted files in, and hit extract.
Using it
Open up the folder where you have just extracted the files and find out TrueCrypt.exe file.
Double click on it to start TrueCrypt.exe

Now, a little about TrueCrypt's working principles. TrueCrypt creates encrypted folders of fixed or dynamic sizes. These folders are only accessible with TrueCrypt, of course, with a password. The folders can be accessed in virtual disks mounted by TrueCrypt.

Next, we would create a volume (which I just called an encrypted folder) by clicking on the create volume button.
Create a file container.
Hit "Next" and in the next step, select "Standard TrueCrypt Volume".
Hit "Next". Now, you are to select the location where you want to create this "volume" (i.e. the file container). Click select file.
I chose my desktop and named it "volume1".
Hit "Next" and in the next step choose the encryption algorithm. Keep the default AES, if you are not sure about what you are doing.
Hit "Next" and in the next step, specify the size of the "volume" (i.e. file container)
In the next step, specify your password.
Hit "Next" and in the next dialog box, click format. (You can play around with the filesystem formats. I prefer FAT though.)
And the volume will be created. (The next dialog box again will ask you to create a volume. Just dismiss it by clicking "Cancel".)

Now, we are to mount this volume.
To do that, select any of the drive letters available there. Don't select any drive letter that is already there, e.g. C: . Here in the screenshot, I selected T

Now, click on "Select file" and in the dialog box, select the volume file we have created.
Next, click on "Mount" to mount the volume. Then comes the password dialog box. Enter your password to mount it.
And voila, it is mounted. Check your My Computer to find the new drive. (T: drive in my case.)
And that's all! :)
