tpm_restrictsrk - restrict the ability to access the Storage Root Key
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. -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 -a, --allow Allow SRK read access using SRK auth -s, --status Display the status of who can access the Storage Root Key -r, --restrict Restrict SRK read to owner 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.
