I'm trying to install Debian in my Dell inspiron 8GB ram + 500GB HD. Althought I could install it without any problems with the regular install and even with a few modifications, I'm trying to maximize my computers security, and therefore I would like to have the / folder encrypted.
Not only that, I would also like that the passphrase for it's encryption was asked before the login screen loaded. The computer will have only one user, and root permissions run trough
sudo. So, the question is:
How do I get to install Debian with a passphrase for encrypted / asked before the login screen?
This is my initial idea to assure security, but I'm open to new ideas and other devices I can use for that purpose.
