							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. -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 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.
