At the time of the first post I used to hide my files (not all were porn) on a linux account called froot
and I was the only one to have that password, Dual boot even back then FTW.
Now when I leave my computer I take my keys which includes a usb fob. As soon as that fob is removed a few directories become encrypted, put the fob back still no joy till you enter 2 passwords. All files in those directories decrypt/encrypt on the fly, I barely even notice the lag except on largish files. A buddy of mine wrote the program so I know it has no backdoors.
