Thread: True Crypt Tutorial

Today I would like to show you how to use truecrypt.

Note: Check your local laws, you could get up to 2 years in jail if you do not provide a password when they ask for it. So make sure you crypt what you really need to hide inside of your crypt.

Lets get started...

This website shows us how secure your password is. This should be simple enough, but I will go ahead and do an example with you all.

Lets say our password is "Ydofu83*#=" and we want to bruteforce it. That is 10 characters long and uses lower, upper, number, and symbols. So that would be 26 (lower) + 26 (upper) + 10 (numbers) + 32 (common symbols) = 96 keyspace.

Now we do 96^10 = 6.64832636 × 10E19 which means it would take more than 2 million years with a supper computer that cracks at 1,000,000 passwords a second.

For more about AES go to http://en.wikipedia....iki/Advanced...

TrueCrypt, the program we will be using, says we should use a password that is at least 20 characters long. I say you should make it 64 characters long because that would make sure that the AES encryption is not only to long, but it also makes the algorithm impossible to decipher.

If you do not believe AES is secure, you can always use Serpent. If AES, Serpent, and/or TwoFish with a 64 character password is still not secure enough for you then you can use a keyfile. TrueCrypt uses on-the-fly encryption/decryption. So this means that the decrypted data is stored in your RAM. Remember that your RAM can be accessed while your PC is on and up to 10 minutes after you turn your PC off. TrueCrypt stores your information in "blocks" which gives you an advantage. Lets say part of the encryption "messes up". Then you cannot decrypt it, well in TrueCrypt it only "messes up" that "block" so you only loose a very small amount of data.

Now let’s get to the installation:
1. Go to TrueCrypt - Free Open-Source On-The-Fly Disk Encryption Software for Windows 7/Vista/XP, Mac OS X and Linux
2. Download TrueCrypt
3. Install Truecrypt
4. Open TrueCrypt
5. Create a TrueCrypt File
6. Create hidden volume.
7. Test
Done


Here is a video demo (not done by me) so you can see exactly how to create a password protected storage using truecrypt.

Note: This is not mentioned in the video above, but if you want you encrypted storage to look and act like a img file, as you save your file add .jpg to the end of the name.
