1 TPM Management - tpm_restrictpubek
tpm_restrictpubek reports the status of who can display the public portion of the Endorsement Key. This is the default behavior and also available with the --status option. This operation will be in effect until the owner is cleared and prompts for the owner passord. With the --restrict option, the ability to display the public portion of the Endorsement Key is resticted to the owner (via the TPM_DisablePubekRead API). The command prompts for the owner password to complete the operation. The --status and --restrict options are mutually exclusive and the last one on the command line will be carried out.

-v, --version Display command version info.
-l, --log [none|error|info|debug] Set logging level.
