gshsec

GSHSEC(8)						    BSD System Manager's Manual 						 GSHSEC(8)

NAME

     gshsec -- control utility for shared secret devices

SYNOPSIS

     gshsec label [-hv] name prov prov ...
     gshsec stop [-fv] name ...
     gshsec clear [-v] prov ...
     gshsec dump prov ...
     gshsec list
     gshsec status
     gshsec load
     gshsec unload

DESCRIPTION

     The gshsec utility is used for setting up a device which contains a shared secret.  The secret is shared between the given providers.  To
     collect the secret, all providers are needed.  If one of the components is missing, there is no way to get any useful data from the rest of
     them.  The first argument to gshsec indicates an action to be performed:

     label    Set up a shared secret device from the given components with the specified name.	Metadata are stored in the last sector of every
	      component.

     stop     Turn off an existing shared secret device by its name.  This command does not touch on-disk metadata!

     clear    Clear metadata on the given providers.

     dump     Dump metadata stored on the given providers.

     list     See geom(8).

     status   See geom(8).

     load     See geom(8).

     unload   See geom(8).

     Additional options:

     -f  Force the removal of the specified shared secret device.

     -h  Hardcode providers' names in metadata.

     -v  Be more verbose.

EXIT STATUS

     Exit status is 0 on success, and 1 if the command fails.

EXAMPLES

     The following example shows how to create a shared secret device.	The secret will be split between a slice on a local disk and a USB Pen
     drive.

	   gshsec label -v secret /dev/ada0s1 /dev/da0
	   newfs /dev/shsec/secret

     From now on, when the USB Pen drive is inserted, it will be automatically detected and connected, making the secret available via the
     /dev/shsec/secret device.

     The gshsec utility appeared in FreeBSD 5.4.
