eCryptfs: An Enterprise-class Encrypted Filesystem for Linux

eCryptfs is a cryptographic filesystem for Linux that stacks on top of existing filesystems. It provides functionality similar to that of GnuPG, except the process of encrypting and decrypting the data is done transparently from the perspective of the application. eCryptfs leverages the recently introduced Linux kernel keyring service, the kernel cryptographic API, the Linux Pluggable Authentication Modules (PAM) framework, OpenSSL/GPGME, the Trusted Platform Module (TPM), and the GnuPG keyring in order to make the process of key and authentication token management seamless to the end user.
