When I installed Ubuntu, I setup an encrypted home partition. Now I have come to an issue where I am running out of memory because I haven't setup swap. How can I setup an encrypted swap file?
A couple of times while booting I've seen some reference to cryptswap. I've also got these lines contained in
# swap was on /dev/sda6 during installation #UUID=1ba8a53b-1842-4de7-8e38-2d6c79f3a1ab none swap sw 0 0 /dev/mapper/cryptswap1 none swap sw 0 0
