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 com-
	     mand 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  se-
     cret 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.
