tpm_restrictsrk - restrict the ability to access the Storage Root Key

tpm_restrictsrk [OPTION]

tpm_restrictsrk reports the status of who can access the Storage Root 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 access the Storage Root Key is resticted to the owner. The command prompts for the owner password to complete the operation. The --allow and --restrict options are mutually exclusive and the last one on the command line will be carried out.
