		      TPM Management - tpm_restrictpubek

NAME
       tpm_restrictpubek  - restrict the ability to display the	public portion
       of the Endorsement Key to the owner

SYNOPSIS
       tpm_restrictpubek [OPTION]

DESCRIPTION
       tpm_restrictpubek reports the status of who can display the public
       portion of the Endorsement Key.	This is	the default behavior and also
       available with the --status option.  This operation will	be in effect
       until the owner is cleared and prompts for the owner passord. With the
       --restrict option, the ability to display the public portion of the
       Endorsement Key is resticted to the owner (via the TPM_DisablePubekRead
       API).  The command prompts for the owner	password to complete the
       operation.   The	--status and --restrict	options	are mutually exclusive
       and the last one	on the command line will be carried out.

       -h, --help
	      Display command usage info.

       -v, --version
	      Display command version info.

       -l, --log [none|error|info|debug]
	      Set logging level.

       -u, --unicode
	      Use  TSS	UNICODE	 encoding  for	passwords   to	 comply	  with
	      applications using TSS popup boxes

       -s, --status
	      Display  the  status  of	who  can see the public	portion	of the
	      Endorsement Key

       -r, --restrict
	      Restrict seeing the public portion of the	Endorsement Key	to the
	      owner

       -z, --well-known
	      Authenticate using 20 bytes of  zeros  as	 owner	password  (the
	      default  TSS  Well  Known	 Secret),  instead of prompting	for an
	      owner password.
