[School of Education] Encrypting Flash Drives With TrueCrypt

This document explains how to encrypt a flash drive using TrueCrypt.

Why should you encrypt your data?

Data encryption is a method of disguising your data. Therefore, even if someone did get ahold of your flash drive that had video data on it, they wouldn't be able to see it without having a password to decrypt it. One way to encrypt your data is with a tool called TrueCrypt.

***BEFORE YOUR START: Make sure that no data is on the flash drive that you plan on encrypting since it could potentially get erased in the process of formatting or encrypting!***

1. Start by going to the TrueCrypt website. http://www.truecrypt.org

2. Under the Downloads tab, if you scroll about halfway down the page, you will see the available downloads. Find your operating system, and click the Download button beneath it.

3. Next, find where the TrueCrypt Setup File. (If you're using Chrome, it is likely in the Downlaods folderon your computer). When you find the file, double click it to begin installing the program.

4. Once you open the TrueCrypt file, you may be prompted with Do you want to allow the following program to make changes to this computer? You can click Yes in this popup. Then, the licensing terms window will open, where you can check I accept the license terms and then click Next.

5. You will then be asked if you want to Install or Extract the file. Make sure the Install bubble is filled in before clicking Next.

6. Next you will see the Setup Options window. Here you can leave everything checked and then click Install.

TrueCrypt should begin installing. This may take a few moments to complete, but when it's finished it should notify you that TrueCrypt has been  successfully installed and you can click OK.

Upon finishing the installation, it will ask you to consider making a donation, the choice is ultimately yours here, but feel free to click Finish. It will then ask you if you want to read through the Beginner's Tutorial; however, this is essentially the beginner's tutorial for you, so you can click, No.

7. Next, you'll want to launch TrueCrypt. To do this, find the program from the start menu, or it should be a shortcut on your desktop. Double click it to launch the program. The main menu window of TrueCrypt should open.

8. Before proceeding to the next step you'll want to mount your flash drive. Then click the Create Volume button just under the list of drives.

9. The TrueCrypt Volume Creation Wizard will launch. You will be asked what kind of encryption  you'd like to do. Since you are encrypting a flash drive, you'll want to choose the Encrypt a non-system partition/drive option. Then click Next. You may be prompted with a message that asks if you would like the program to make changes to the computer. Click Yes.

10. In the next window, you will be asked to choose a Volume Type. You can simply click Standard TrueCrypt Volume, and then click Next.

11. It will then ask you to choose the Volume Location. In the upper right hand portion of that window you will see the Select Device Tab, click that. All of your system hard drives should be displayed at the top, and then towards the bottom of that list you should see Removable Disk 1: and beneath that you should see  \Device\Harddisk1\Partition1\ (in this example the Drive was G:. but just know that yours may load as a different letter). Click the removable drive. It should then be highlighted in blue, as pictured. Then, click OK.

You will be returned to the Volume Location window. You should see your device displayed. Click Next.

12. The next window will ask you to choose the Volume Creation Mode. Because you will also need to format the flash drive as well as encrypt it, select the Create Encrypted Volume and Format It option, then click Next.

13. The Encryption Options window will open next. You can leave everything the same here, and click Next.

14. Next, you'll be asked to verify the size of the volume. In this example, the flash drive is an 8 GB flash drive; therefore, 7.45 GB is correct. Just know that your screen may differ depending on how large your flash drive is. Click Next.

15. You will then be prompted to create a password for the volume. The paragraph below where the password is entered provides some good tips for creating secure passwords. You're encouraged to read this through before creating your password. DO NOT FORGET YOUR PASSWORD! When you are finished, click Next.

16. It will ask you next if you intend to store files larger than 4 GB on the flash drive. Since you will be working with large video files,  you will want to select Yes here before clicking Next.

17. In the next window you will be asked to select the Format for the flash drive. For your purposes you will want to make sure that the Filesystem is NTFS. Everything else in this window you can leave as default. Then click Format. Move your mouse a lot, and as randomly as possible in this window in order to increase the strength of the encryption keys.

18. Once formatting begins, a warning window will open notifying you that any data currently stored on the device will be lost. Click Yes to proceed with formatting. Formatting will begin. It could take upwards of 15 minutes to format the drive, so be patient. Once this is done, your device should be encrypted and ready to use.
