1 TPM Management - tpm_takeownership
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.
