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.

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.[1] It also allows for encryption to be applied selectively on a per-file or per-directory basis.


eCryptfs is derived from Erez Zadok's Cryptfs.[2]
