.SH NAME
takeown \- takes "ownership" of the TPM device
.SH SYNOPSIS

takeown <owner password> [<srk password>]

     
.SH DESCRIPTION
The \fBtakeown\fP command is used to create the owner of a TPM,
and also create the SRK (Storage Root Key).
This command can only be issued if the TPM currently has no owner.
This command should
be used with caution.
.SH ARGUMENTS
.TP 5
owner password
is any character string, up to 256 bytes long.
This password will be needed to perform a number of TPM operations
that require authorization by the TPM "owner".
.TP 5
srk password
is any character string, up to 256 bytes long.
This password will be needed to use the SRK, in particular to load
any keys created as children of the SRK.
If omitted, the SRK will be created with a flag indicating that no
authorization is required for use, and with a dummy authorization value
of all zeros.
.SH FILES
The command will also create a disk file, called \fBsrootkey.pem\fP,
which is an OpenSSL PEM format public key, and contains the public
key portion of the new SRK.
