[Context]
It is my third time installing arch and I've use it for a bit more than a year now. I want to make a secure installation by encrypting my system.
[Question]
After reading the wiki about LVM and DM-CRYPT, I must confess that I'm a bit lost with all of this and don't really know where to start and what to do. Can someone enlighten me on this topic and potentially give me a quick guide on how to do this. Ideally I would have a USB-drive with a keyfile and still a passphrase in case I lose the USB-drive and it would intervene at the boot (I'm not sure if it is really possible though)
[hardware]
I have two hard drive, a 500MB SSD and a 1TB HDD
thanks in advance for help
