EncFS

EncFS provides an encrypted filesystem in user-space. It runs without any special permissions and uses the FUSE library and Linux kernel module to provide the filesystem interface. You can find links to source and binary releases below. As with most encrypted filesystems, Encfs is meant to provide security against off-line attacks; ie your notebook is stolen, your backups are stolen, etc. The way Encfs works is different from the loopback encrypted filesystem support built into the Linux kernel because it works on files at a time, not an entire block device. This is a big advantage in some ways, but does not come without a cost. http://arg0.net/users/vgough/encfs.html
