[Haifux] Whole disk encryption, because it costs nothing?

Hello, I suppose that by now some of you have realized that I'm working on setting up my new computer. ;) The new question is whether I should encrypt the whole hard disk, including the swap partition (minus, possibly, a read-only mounted /boot). Just so I don't need to worry in case my

I wound up setting up an encrypted partition, but only placing there things I consider sensitive (which does include the swap, mail, client's sources, my family images etc.), as well as some other automatically generated stuff (such as /var/lib/mlocate and ~/.bash_history, both via symlinks).

Please note that the next generation of Intel CPUs (starting at February!) are going to have an AES instruction built in them, making harddisk encryption (using AES) extremely efficient (we're talking at about 4 cycles/byte in stupid modes and about 0.7 cycles per byte in more useful modes). AMD

Sequential IO is very simple, relatively, so that you will hardly feel the performance impact testing it. Test random IO loads with small packets (0.5K-4K) and you will probably feel the performance impact there. Ez On Mon, Jan 11, 2010 at 7:00 PM, Eli Billauer e...@billauer.co.il wrote:
