NAME
tpm_takeownership - setup an owner on the TPM
SYNOPSIS
tpm_takeownership [OPTION]
DESCRIPTION
tpm_takeownership setup an owner on the system's TPM (via the TPM_TakeOwnership API). This operation requires the TPM to be enabled and
can be restricted by tpm_setownable. The command will prompt for owner and SRK passwords and confirmations of these if executed without
either of the -well-known options, otherwise, a secret of all zeros is set for the requested password. After the second confirmation, be
patient as the command may take awhile.

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.

-p, --prevent
Prevent tpm_takeownership operations.
-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.
