Also encryption done well should not rely on some particular hardware being closed or the algorithm secrete, like this system does, but only on the secrete that the user know, the password or other authentication methods. Like disk encryption with Linux, you select a robust password, or you can store a key in whatever way you want, you enter your password on boot and unlock the disk, if you PC broke, fine remove the disk from the computer and put it in another. The security lies only in the password you choose, not your particular PC having some kind of closed hardware in which somewhere lies the key (of course).
