[kwlug-disc] Encrypted file systems

My father has the need to keep some files secure in case someone breaks into his home (before you think it's far fetched: He lives in Mexico City).

The computer is a "common" computer in his den used every now and then by my siblings and other people (My parents are quite social). He does not want to block access to the computer to the people that already use it occasionally.

My first thought was to set up a partition with an encrypted file system in an external drive for him to put the private files there. This way he can have logical and physical security.

This computer is dual boot: Ubuntu 8.04 LTS / Windows XP Home  and ideally he wants to be able to access the files from either OS.

What encryption method or mechanism do you think would work better for him? If there aren't any cross platform, which one would be the best to do it in Linux?

Performance or latency are not a concern, he has a new quad core. Most of the files would be smaller files.
