TPM Management - tpm_setclearableNAMEtpm_setclearable - disable TPM clear operations
SYNOPSIStpm_setclearable [OPTION]
DESCRIPTIONtpm_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.
