TrueCrypt 5 finally got what I ever looked for

Yes, finally TrueCrypt offers you encryption of your whole hard drives. That feature I was looking for for ages. I was noticed about the new TrueCrypt-Version by Thomas from Glorf-IT, later on I read the article on heise.

I immediately downloaded the new version and started installing it. On my laptop. Not on my PC. On my laptop is only data that is stored on my pc's drives so there is no actual loss if something is messed up up afterwards.

The Installation process starts as usual, installing the new TrueCrypt on your computer. Then after starting I recognized this nice menu entry Encrypt System Partition/Drive... Well, that's is the killer feature.

Now, guess, what the first action was I did with the new version. I just clicked on it. In the following process TrueCrypt asks you for several things; do you want to encrypt only the windows system partition or the whole disk drive? Is it a single boot or multi boot-system? Next question is: What encryption algorithm do you want? If you cannot decide, you can benchmark your system and select the fastest one. After choosing one you have to specify the password. And this password should a a) safe (letters, numbers, special characters, randomly mixed) and b) unique (don't use a password you used anywhere else).
After that you find yourself inside the matrix. TrueCrypt pops up a dialog that tracks your mouse movement above this dialogue. The generated data are used for encryption. So, the longer and the more randomly you move, the better the encryption will be.

After this, the actual keys are calculated. The next step convinced me that everything I'm doing is well planned and even for common users no big deal at all. TrueCrypt wants me to save a TrueCrypt Rescue Disc.
What is a True Crypt Rescue Disc? Quite simple. It is a disk with three parts that will help regain your data if anything goes wrong during the encryption process or later on using your encrypted drive. With the TRD four things can be done. These are:
  • Information is stored to restore your TrueCrypt boot loader, your master key, or other critical data.
  • The TRD itself is bootable and loads afterwards the system that is stored inside your encrypted volume.
  • If your system gets damaged, the TRD can decrypt the volume for external access.
  • The TRD contains a backup of the first drive cylinder. That cylinder usually contains the system boot loader., so the original statecan be restored.
After saving this ISO-file, you have to burn it. TrueCrypt stops working until it has verified the data on the CD. That means, you are forced to burn the CD. Well, from my point of view this is a very smart way to prevent data loss. And TrueCrypt also provides you two tools for burning it. What a service. Kudos to the TrueCrypt-Team. This is just a amazing piece of software with many detailed thoughts went into.

So, next step. When the CD is verified, you can choose if and how often your hard drive shall be wiped before the actual encrypted data is stored. Because of the time consumption and the data I have on my laptop, I decided not to wipe my drive. While nearing completion TrueCrypt now does a testboot with the boot loader installed and where you have to enter your password. If this test boot is ok, you can press the red button and start encrypting your drive.

In résumé there is just to say that TrueCrypt 5 is a leap forward in free cryptography and personal securirty. And this whole thing is presented in an easy to use way. Everyone out there who never thought about personally securing his data, just give it a try. And wish me luck. 49 minutes remianing until my drive is finished :)
