		      TPM Management - tpm_takeownership

NAME
       tpm_takeownership - setup an owner on the TPM

SYNOPSIS
       tpm_takeownership [OPTION]

DESCRIPTION
       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.
