Encrypting Your Stuff – Create a TrueCrypt container for DropBox

In our last post we talked about containers. If you think about a container as a large box that you put things in, you’ll have the right idea. Today, let’s lock that box up tight using TrueCrypt.

We’ve written about TrueCrypt before but it’s certainly worth another post. First, it’s free and, second, it’s the easiest encryption tool we’ve ever used. Download it here: TrueCrypt

Point A. TrueCrypt can be installed on your computer or you can run it from a folder on your desktop (or anywhere else for that matter). It’s self-contained, in other words, able to run without being installed on your computer.

Tip: You can carry a copy of TrueCrypt around on a flash drive with your container. You would use TrueCrypt to open the container, interact with the contents then lock it up again.

Point B. Basically, you will create a folder, name it, encrypt it and use a password to lock it. TrueCrypt is very simple to use but we’ll run through the steps using screen captures, just so you don’t screw things up. In reality, the only thing you have to worry about is forgetting your password. If you do, everything in the encrypted folder is lost for good. That’s how powerful TrueCrypt is.

Here we go:

1.

The TrueCrypt opening menu. You want to click on ‘Create Volume’.

 

2. TrueCrypt has a few options to choose from but we want to do the simplest set-up here.

Choose the first one, ‘Create an encrypted file container.’

 

3. Again, stick with the simplest volume (container):

We just want a Standard TrueCrypt volume here, nothing fancy.

4. The next menu is a bit confusing. Take a look:

This is the most confusing part. Read our description of this menu.

This menu seems to be asking you to choose a file/container, as if you have already created one. You haven’t created one yet but you will now. Don’t type anything in the space, just click the ‘Select File’ button. When the file menu opens, navigate to your Desktop. You can put the new file anywhere but we find it easier if it’s right in front of us, right there on our desktop. Read the warning! Do not choose an existing file. TrueCrypt will delete it and create a new file using the same name. Repeat, do NOT choose an existing file. Read step 5. 

5. After you have navigated to your desktop, your next job is to type a name  in the slot. You could name your new file Mary, Joe, Sparky, whatever you want. You can simply use a name or a number or an obscure combination of letters and numbers, it doesn’t matter. We would suggest, however, using a name and a file type. Why? We want a file type because someone who is looking for a hidden file would probably not look for a photo or video file, right? That’s why we named our file, ‘summertime.avi’. It’s not really an ‘avi’ file, though. It can’t be opened by any program other than TrueCrypt.

We chose to use ‘avi’ as the file type but you can use .txt or .docx or .dll, whatever.

5. Once you click Save, TrueCrypt knows that the file it creates will be named, in our case, summertime.avi. Next, TrueCrypt will ask you what kind of encryption algorithm you want to use. Go with the defaults here unless you know what you’re doing.

Go with the flow, use the default settings here.

6. How big should your container be? Only you know that. For our example, we set it to 1 gigabyte in size.

Don’t make it too small, use a decent size.

7. Next comes the password. Use a good one. Make sure you don’t forget it. Read the tips that TrueCrypt gives here. You can always change the password later on, no worries.

A good password is vital.

8. If your password is too short, TrueCrypt warns you about it.

Danger Will Robinson!

9. Now comes the fun part. You’ll never see this anywhere else. You are now creating the encryption key as you move your mouse over this menu box. Take your time and do what the instructions tell you. Once you’re bored of darting back and forth, click Format and TrueCrypt will create the volume/container for you.

Move your mouse up and down, around and around, back and forth.

10. This is what you should see next:

Photo of TrueCrypt Container   10
Success! If you don’t see this, you screwed up somewhere but we think you’ll be fine.

11. OK, you’ve created the container. It’s sitting on your desktop waiting to be used. How do you open it?

Photo of TrueCrypt Container   11
There is our ‘summertime.avi’ file on the desktop.

Well, you won’t open that file with anything but TrueCrypt.

12. Using the same technique as before, navigate to the file on your desktop. What you want to do now is to tell TrueCrypt to ‘mount’ the container you just created. (Container, volume, file, all the same thing.)

Photo of TrueCrypt Container   12
When you get to the file, click Mount to open it.

13. TrueCrypt will ask for your password. Again, don’t forget it.

Photo of TrueCrypt Container   13
Don’t ‘Cache passwords and keyfiles in memory’ OK?

14. Click OK and the file is shown in the TrueCrypt window:

 

Photo of TrueCrypt Container   14
There is ‘summertime’avi’ waiting to be opened. Double click on it now.

15. You’ve managed to create an encrypted container that is locked with a strong password. Now it’s time to fill it with your stuff:

Drag and drop files into this folder/container/volume up to the limit of room it has in it.

16. When you have finished adding files, make sure you click Dismount All before  you close TrueCrypt. You mount the volume, enter the password, add or look at the files in it, then close the folder then dismount it in TrueCrypt. Don’t forget the last part.

 

This is a long post, next time we’ll explain the DropBox part of it. Thanks for sticking with us so far!

 

 

 

Protect Your Privacy with TrueCrypt – Part 3



In our last post, we created an encrypted volume using Truecrypt. This volume could be thought of as a folder but it’s a bit more than that. If you think of this thing that you created as a separate drive on your computer, you will have a better picture of what it really is. When you add a new hard drive to your computer, you have to mount it before you can use it. Before you can use your newly created folder, you also have to mount it. Using Truecrypt, we’ll show you how to mount the new volume in order to make use of it. 1. The new volume (folder) should be on your desktop. It may or may not have a three digit file-type  designation, depending on how you chose to name it. If you didn’t use a three letter name, such as .avi or .mp3, Windows will not use an icon to give you an idea of what it thinks it is. Here’s what our volume looks like:

Windows knows there is something there, it just doesn’t know what.

Just a simple, generic page icon. Windows does not associate a program with this volume/folder. You can’t double-click it to open it, right? Don’t forget that. Open Truecrypt now.   2. When Truecrypt is open, you’ll see this screen:

Photo of Truecrypt   opening menu
You are looking for ‘Select File’ then ‘Mount’.

This is a standard Windows dialogue/menu, nothing different from most other programs. You open the program first, then use it to open a file that it can handle. Click on Select File, find the volume that you created then click Open to go back to the menu shown below.   3. Here is what you should see next :

Photo of Truecrypt  menu
The path to the file is there in the window and a drive letter may or may not be highlighted in blue.

You will see a number of drive letters in this menu, everything from G to Z. Choose a letter that isn’t currently being used by your computer. You’re pretty safe with anything past O or P. We have chosen T for this drive. Click on the word ‘Mount’ on the lower left of the menu.   4. Make sure you have the password that you used to create this volume. Truecrypt will prompt you for the password:

Photo of Truecrypt password menu.
Type in the password that you used to create this volume.

If you forget your password, there is nothing that you can do to retrieve it. Whatever volume you created is lost for good. Don’t lose your password. You’ve been warned.   5. Once you enter the correct password, Truecrypt will mount the volume. In other words, it will allow you to access it. It’s not open yet but it is accessible. This is what you should have on your screen now:

Photo of mounted Truecrypt   drive.
There it is by the letter T. Note the size difference of the folder.

This drive is now accessible in two different ways. You can either double-click it now on the Truecrypt  menu or navigate to it through Windows Explorer. In our case, it is listed as ‘Local Disk T’. Once you open the drive/volume/folder, drag and drop something into it. We chose to keep our encrypted text password document in ours. In this way, our passwords are protected by two walls, one through Notepad ++’s encryption and the other through Truecrypt ‘s. TIP: After you put the files into this volume/folder/drive, make sure that you dismount it before you close down Truecrypt. The process is this: Mount the drive, add or subtract files into it, dismount it. You can’t open the volume without mounting it and you should not close it without dismounting it. This is the only way that Truecrypt can guarantee to keep its contents safe. Two long and fairly convoluted posts, right? Keeping your data safe isn’t simple but we feel that using Truecrypt doesn’t require much tech savvy. If you follow our simple step-by-step instructions, you’ll be fine. What’s next? Moving this folder around inside of Dropbox. One more post on this topic and we’re done. Thanks for reading!
