I know you wanted this, the Ubuntu team also knew and they've implemented it in the new version of Ubuntu, Gutsy Gibbon. Unfortunately, it's only available in the text mode installer, but that's why this guide is here, to help you install a fully encrypted Ubuntu OS on your computer. This process is completely safe and it is recommended to be used by anyone out there who wants to protect his/her sensitive data. To break it down to you: No more living in fear! Your data will NOT be stolen anymore!
What are the benefits of this encryption?
￭ Everything on that disk (including the swap space) are fully encrypted. Encrypting temporary (swap) files is important, as they can reveal important confidential data.
￭ With full disk encryption, the decision of which files to encrypt is not left up to users.
￭ Support for pre-boot authentication.
￭ Immediate data destruction! How? By simply destroying the cryptography keys. However, if security towards future attacks is a concern, file wiping or physical destruction is advised.
The only disadvantage of this encrypted installation is that it will take between 6 to 10 times longer than a normal (unencrypted) installation.
