			TPM Management - tpm_setenable

NAME
       tpm_setenable - change TPM enable states

SYNOPSIS
       tpm_setenable [OPTION]

DESCRIPTION
       tpm_setenable reports the status	of the TPM's flags regarding the
       enable state of the TPM.	 This is the default behavior and also
       accessible via the --status option. Requesting a	report of this status
       prompts for the owner password.	The --enable option changes the
       system's	TPM to the enabled state (via the TPM_OwnerSetDisable API).
       This operation prompts for the owner password and is persistent.	The
       --disable option	(via the TPM_OwnerSetDisable API) changes the system's
       TPM to the disabled state.  This	operation prompts for the owner
       password	and is persistent.  A disabled TPM is essentially off and does
       not allow a tpm_takeownership to	occur.	The --force option overrides
       the owner password prompt and relies on physical	presence for the
       operation authorization (via the	TPM_PhysicalEnable and
       TPM_PhysicalDisable APIs).  The --enable, --disable, and	--status
       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]

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

       -s, --status
	      Report the status	of flags regarding the TPM enable states.

       -e, --enable
	      Make the TPM enabled.  Operation is persistent and  prompts  for
	      owner authorization.

       -d, --disable
	      Make the TPM disabled.   Operation is persistent and prompts for
	      owner authorization.

       -f, --force
	      Overrides	 the  prompt for owner authorization and uses physical
	      presence to authorize the	action.

       -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.
