eCryptfs (Enterprise Cryptographic Filesystem) is a package of disk encryption software for Linux. It is implemented as a POSIX-compliant filesystem-level encrypted file system that has been part of the Linux Kernel since version 2.6.19. The eCryptfs package has been included in Ubuntu since version 9.04. It works similarly to Microsoft's Encrypting File System.
Filesystem-level encryption has certain advantages and disadvantages over full disk encryption. Whereas full disk encryption works at the block-level, requiring an additional file system to be mounted over the top in its own partition, filesystem-level encryption can exist within an existing partition, requiring no specific block area to be set aside for its use. It also allows for encryption to be applied selectively on a per-file or per-directory basis.
