Projects / eCryptfs


eCryptfs is an POSIX-compliant enterprise-class stacked cryptographic filesystem for Linux. It is derived from Erez Zadok's Cryptfs, implemented through the FiST framework for generating stacked filesystems. It extends Cryptfs to provide advanced key management and policy features. It stores cryptographic metadata in the header of each file written, so that encrypted files can be copied between hosts; the file will be decryptable with the proper key, and there is no need to keep track of any additional information aside from what is already in the encrypted file itself. Think of it as a sort of "gnupgfs.'' It is a native Linux filesystem, and can be built and distributed as a stand-alone kernel module for Linux 2.6.15 or higher.
