NAME

       gfsec-split - Split a file into shares and dispatch them

SYNOPSIS

       gfsec-split [-h|--help] [-v|--version] [-n|--threshold N] [-c|--config file]
                   [-i|--interactive] [-k|--keep] [-o|--output file] [-r|--restore-cmd command]
                   [-d|--destroy-cmd command] [-l|--list-supports] file URI...

DESCRIPTION

       gfsec-split splits a file into a number of shares and dispatches the resulting shares onto
       external storage supports.

       The split file can then be temporarily reconstructed using the accompanying program gfsec-
       use(1).

OPTIONS

       -h, --help
              Display the help message.

       -v, --version
              Display the version message.

       -n, --threshold N
              Specify  the  minimal  number  of  shares  required  to re-assemble the split file.
              Default is 2.

       -c, --config file
              Write the configuration file (allowing to reconstruct the secret with  gfsec-use(1)
              )   to  the  specified  file.  Default  is  the  basename  of  the  split  file  in
              $XDG_CONFIG_HOME/gfsecret.  If FILE is a  single  filename  without  extension  and
              without    a    directory    part,    the   file   will   be   placed   under   the
              $XDG_CONFIG_HOME/gfsecret directory with a .conf extension.

       -i, --interactive
              Present the user with an interactive menu to specify the shares to create.

       -k, --keep
              By default, gfsec-split will delete the original file once it has been successfully
              split.  Use  this  option  to  prevent  the  file to be deleted.  -o, --output file
              Specify the location where gfsec-use  will  write  the  reconstructed  secret.  The
              default  is  to  use  the original location. If set to an empty string, no location
              will be written in the configuration file.  -r, --restore-cmd command  Specify  the
              command  that gfsec-use will call to restore the secret.  -d, --destroy-cmd command
              Specify the command that gfsec-use will call to destroy the secret when  it  is  no
              longer  needed.  The same command will also be called by gfsec-split to destroy the
              secret once it has been split, unless the -k option has been used.

       -l, --list-supports
              List all the currently available supports which can be used to store  shares,  then
              quit.

SHARE URIs

       Shares  are described using a URI-like syntax. For each share, the URI indicates a storage
       device and a pathname on that device.

       Supported URI schemes are:

       file:///
              Indicates a file on the local filesystem.

       uuid://uuid/
              Indicates a file on the external volume identified by the specified UUID.

       label://label/
              Indicates a file on the external volume identified by the specified label.

       mtp://serial/
              Indicates a file on the MTP device identified by the specified serial number.

       http://host/
              Indicates a file on a web server identified by its hostname.

       https://host/
              Same as the previous one, but the web server is to be  accessed  through  a  secure
              connection.

EXAMPLE INVOCATION

       gfsec-split \
         /home/alice/mysecret \
         file:///home/alice/.local/share/gfsecret/mysecret \
         label://USBSTICK/mysecret \
         mtp://RF2GB6X704P/Documents/mysecret \

       The  above  example will split the file /home/alice/mysecret into three shares: one on the
       local filesystem, one on the USB mass storage device with the label USBSTICK, and  one  on
       the  MTP-compliant  device  with  the  serial  RF2GB6X704P.   A configuration file will be
       written in $XDG_CONFIG_HOME/gfsecret/mysecret allowing to  automatically  reconstruct  the
       file with gfsec-use(1) provided at least one of the two removable supports are present.
