encfs

Userspace Encrypted File System

EncFS provides an encrypted file system, layered on top of a normal directory tree and encrypts individual files which are stored in the hosting directory tree. This has several advantages over the loopback encryption which provided by the Linux kernel: - No space is and has to be reserved, encrypted files only take the space that they really occupy - Backups: encrypted files can be individually backed-up on the host filesystem - Layering: Since it's hosted on a normal filesystem, encfs can be used on filesystems which normally have no support encryption, like NFS or other userspace filesystems. EncFS is implemented as a userspace filesystem in an unprivileged application using fuse (FUSE (Filesystem in USErspace)).
