NAME
tpm_changeownerauth - change the authorization data associated with the owner or SRK
SYNOPSIS
tpm_changeownerauth [ OPTION ]
DESCRIPTION
tpm_changeownerauth
allows for changing the authorization data for the TPM owner
or the TPM’s Storage Root Key (via the
TPM_ChangeAuthOwner API). This operation prompts for current
password, followed by the new password and a confirmation of
the new password. The
--owner
option changes the TPM
owner password and
--srk
option changes the
TPM’s SRK password. The
--well-known
option is
used when SRK or owner passwords need to be changed and
current owner password is a secret of zeros,
--set-well-known
option changes current password to a
secret of zeros, both options do not work by themselves,
they must be used with
--owner
and
--srk
options to indicate which of these passwords will be
changed.
