Encrypt filesystems with EncFS and LoopAES

Encrypted filesystems may be overkill for family photos or your r?sum?, but they make sense for network accessible servers that hold sensitive business documents, databases that contain credit card information, offline backups, and laptops. EncFS and LoopAES, which are both released under the GNU General Public License (GPL), are two approaches to encrypting Linux filesystems. I'll compare the two and then look at other alternatives.

EncFS provides an encrypted filesystem in userspace and runs without any special permissions. In fact, it's not so much a filesystem as a program that translates requests (encrypting or decrypting them as appropriate) and passes them to the underlying filesystem. It uses the Filesystem in Userspace (FUSE) library and kernel module to provide the filesystem interface, and it uses a pass-through filesystem as opposed to an encrypted block device.
