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.
