eCryptfs - an enterprise-class cryptographic filesystem for linux mount -t ecryptfs [SRC DIR] [DST DIR] -o [OPTIONS] eCryptfs is a 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. eCryptfs extends Cryptfs to provide advanced key management and policy features. eCryptfs 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 eCryptfs as a sort of "gnupgfs."

STANDARD OPTIONS
Specify the type of key to be used when mounting eCryptfs. Specify the symmetric cipher to be used on a per file basis Specify the keysize to be used with the selected cipher. If the cipher only has one keysize the keysize does not need to be specified. Allows for non-eCryptfs files to be read and written from within an eCryptfs mount. This option is turned off by default.

KEY OPTIONS
The actual password is password. Since the password is visible to utilities (like ’ps’ under Unix) this form should only be used where security is not important. The password should be specified in a file with passwd=(passphrase). It is highly reccomended that the file be stored on a secure medium such as a personal usb key. The password is specified through the specified file descriptor. The user types their passphrase in through stdin. The salt should be specified as a 16 digit hex value. The filename should be the filename of a file containing an RSA SSL key. mount(8) Do not run eCryptfs in higher verbosity levels unless you are doing so for the sole purpose of development, since secret values will be written out to the system log in that case. Please send bug reports to the lead developer, an eCryptfs mailing list hosted from SourceForge, or to the SourceForge bug tracker for the eCryptfs project. For kernel bugs, please follow the procedure detailed in Documentation/oops-tracing.txt to help us figure out what is happening.
