TPM Management - tpm_setclearable
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.
