1 TPM Management - tpm_setownable

NAME
tpm_setownable - change whether the TPM allows tpm_takeownership operations
"SYNOPSIS"
tpm_setownable [ OPTION ]
"DESCRIPTION"

tpm_setownable reports the status of the TPM's flags regarding if the TPM can be owned. This is the default behavior and also accessible via the --status option. Requesting a report of this status prompts for the owner password. The --allow option sets the system's TPM to allow tpm_takeownership operations (via the TPM_SetOwnerInstall API). This operation requires physical presence. The --prevent option (via the TPM_SetOwnerInstall API) prevents the TPM from accepting tpm_takeownership operations. This operation requires physical presence. These operations are persistent. tpm_takeownership requires the tpm be enabled.

-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 if the TPM can be owned.
