So i was watching hak5 and the past two episodes have had truecrypt in them. I’ve been using truecrypt for about one or two years and I have to say that I use it a lot. I’m big on encryption and protecting my files. I encrypt everything usb drives, hard drives, and container files. One thing that caught me by surprise was the fact that cold booting can be used to get the AES encryption from your systems RAM. Now I’ve known about cold booting since MIT came out about it but its interesting to see it can be used to get data. Overall truecrypt is better than nothing. Cold boot can’t work unless someone has physical access to your computer.
I’m going to show how you can make a simple container file. If you encrypt a usb/hard drive you could lose data. So here it is:
Open truecrypt…..

Next your going to select create volume……

Select create an encrypted file container and press next…..

Now the difference between standard and hidden volumes is that the standard volume is just put your password in and a keyfile if you wanted one and your in. The hidden volume is there are two passwords lets say you have sensitive data and someone forces you to open it. You can put one password in where you might have some pictures. But the other could be what opens your sensitive data. Just to learn to use truecrypt we’ll do standard and press next you should be here now….

Choose your location then press next…

Going over the encryption types will take a long time the best explanation can be found on the truecrypt website. But I feel that cascading encryption are more secure. And i personally like to use whirlpool algorithm. Cascadeing encryption would be two or three encryptions instead of just AES you would choose AES-Twofish or Serpent-Twofish-AES. Its just a little more secure because there are ways to get AES keys if you know how to. Here are my selections…..

Then press next when you finish your selection.
The next thing you need to choose is the size from kb, mb, or gb for your file. I’ll choose 512 mb just for this example. Once you choose the size press next…..
Now we’re at the password section. To have the best possible protection use a long password around 126 characters. I like the use of key files. If you choose to use a key file it can be a picture, text file, etc. Just be aware if the first few kb of the file is changed then the key file will no longer work. So its best to use something you wont be changing.
Now where at the volume format once you press next……

The reason it asks you to move your mouse around is because it uses the random points your mouse makes to make the encryption stronger. The more you move it the stronger you encrypted file will be. Once you feel ready press format….

Once completed a little pop up box saying it was successfully completed. That’s all there is to created it. In the location you chose you should have a file like this….

In order to open the file put the file location in the main window choose a drive letter and press mount.
Then you have to put you password word and a key file if you chose to…..

Once you press okay it will be mounted to you system as if it was a real hard drive. So there you go. Play around with truecrypt and have fun learning.
