NAME

       tpm_setclearable - disable TPM clear operations

SYNOPSIS

       tpm_setclearable [OPTION]

DESCRIPTION

       tpm_setclearable reports the status of the TPM's flags regarding how the TPM can be cleared.  This is the default behavior and also
       accessible via the --status option. Requesting a report of this status prompts for the owner password.  The --owner option requests that
       the TPM disable clear operations (via the TPM_DisableOwnerClear API) disabling the owner from clearing out the ownership information.  This
       operation prompts for the owner password.  This operation is in effect until the current owner is cleared.  The --force option (via the
       TPM_DisableForceClear API) disables using Phyiscal Presence to authorize a clear operation.  This operation does not require authorization
       and will skip the owner password prompt.  This operation is only in effect until a reboot.

       -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
	      Report the status of flags regarding how the TPM can be cleared.

       -o, --owner
	      Disable use of owner authorization for authorizating a clear operation until a new owner exists.

       -f, --force
	      Disable use of Physical Presence for authorizating a clear operation until a reboot has occurred.

       -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.

NAME

       tpm_setactive - change TPM active states

SYNOPSIS

       tpm_setactive [OPTION]

DESCRIPTION

       tpm_setactive reports the status of the TPM's flags regarding the active 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 --active option changes the TPM
       to the active state (via the TPM_PhysicalSetDeactivated API).  This operation requires evidence of physical presence, is persistent and
       requires a reboot to take effect. The --inactive option (via the TPM_PhysicalSetDeactivated API) changes the TPM to the inactive state.
       This operation requires evidence of physical presence, is persistent and requires a reboot to take effect.  An inactive TPM is essentially
       off but still allows for a tpm_takeownership to occur.  The --temp option causes deactivation (via the TPM_SetTempDeactivated API) to
       happen immediately but only endure for the current boot cycle.  The --status, --active, --inactive, and --temp 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
	      Report the status of flags regarding the TPM active states.

       -a, --active
	      Make the TPM active.  Operation is persistent, requires phyiscal presence to authorize, and a reboot to take effect.

       -i, --inactive
	      Make the TPM inactive.   Operation is persistent, requires phyiscal presence to authorize, and a reboot to take effect.

       -t, --temp
	      Makes the TPM inactive for the current boot cycle only.

       -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.
