What is the best file encryption for linux?

[William Park]

As others have said, I'm aware of 2 kinds:
    1. cryptsetup -- block layer under the filesystem
    2. ecryptfs -- kernel module mounted on top of directory
Both will be transparent while mounted, so probably the easiest to use.
If your thief steals it while turned on, then all bets are off. :-)
