.SH COMMANDS
|
|
.TP
|
|
.B e4crypt add_key -S \fR[\fB -k \fIkeyring\fR ] [\fB-v\fR] [\fB-q\fR] [ \fI path\fR ... ]
|
|
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.
|
|
.IP
|
|
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.
|
|
.TP
|
|
.B e4crypt get_policy \fIpath\fR ...
|
|
Print the policy for the directories specified on the command line.
|
|
.TP
|
|
.B e4crypt new_session
|
|
Give the invoking process (typically a shell) a new session keyring,
|
|
discarding its old session keyring.
|
|
.TP
|
|
.B e4crypt set_policy \fIpolicy path\fR ...
|
|
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.
