The ideia is: you can run the system but you cannot access the sources 
inside it, what is very interesting when you work with PHP, for example.

So, when machine is off nobody can read data from it because it is encrypted.

When you turn the machine on it automatically enter a passphase or key 
witch are hidden somewhere that we cannot detect! Amazing!

My guess is that the keys/passphrase are compiled inside the kernel, so 
it´s quite impossible to access it, but at the same time you can use the

I used the system without internet access and it mounted the partition 
ok! That´s why I think that the "magic" is in the kernel! 

Any ideas how it´s done?
