e4crypt - ext4 filesystem encryption utility
e4crypt add_key -S [ -k keyring ] [-v] [-q] [ path ... ]
e4crypt new_session
e4crypt get_policy path ...
e4crypt set_policy policy path ...
e4crypt performs encryption management for ext4 file systems.
e4crypt add_key -S [ -k keyring ] [-v] [-q] [ path ... ]
Prompts the user for a passphrase and inserts it into the
specified keyring. If no keyring is specified, e4crypt will
use the session keyring if it exists or the user session
keyring if it does not.
If one or more directory paths are specified, e4crypt will try
to set the policy of those directories to use the key just
entered by the user.
e4crypt get_policy path ...
Print the policy for the directories specified on the command
line.
e4crypt new_session
Give the invoking process (typically a shell) a new session
keyring, discarding its old session keyring.
e4crypt set_policy policy path ...
Sets the policy for the directories specified on the command
line. All directories must be empty to set the policy; if the
directory already has a policy established, e4crypt will
validate that the policy matches what was specified. A policy
is an encryption key identifier consisting of 16 hexadecimal
characters.
