tpm_setownable - change whether the TPM allows tpm_takeownership operations
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. -a, --allow Allow tpm_takeownership operations. -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.
