config ECRYPT_FS tristate "eCrypt filesystem layer support" depends on KEYS && CRYPTO && (ENCRYPTED_KEYS || ENCRYPTED_KEYS=n) select CRYPTO_ECB select CRYPTO_CBC select CRYPTO_MD5 help Encrypted filesystem that operates on the VFS layer. See <file:Documentation/filesystems/ecryptfs.txt> to learn more about eCryptfs. Userspace components are required and can be obtained from <http://ecryptfs.sf.net>. To compile this file system support as a module, choose M here: the module will be called ecryptfs. config ECRYPT_FS_MESSAGING bool "Enable notifications for userspace key wrap/unwrap" depends on ECRYPT_FS help Enables the /dev/ecryptfs entry for use by ecryptfsd. This allows for userspace to wrap/unwrap file encryption keys by other backends, like OpenSSL.
