tss2_pcrextend(1)	    General Commands Manual	     tss2_pcrextend(1)

NAME
       tss2_pcrextend(1) -

SYNOPSIS
       tss2_pcrextend [OPTIONS]

SEE ALSO
       fapi-config(5)  to  adjust  Fapi	parameters like	the used cryptographic
       profile and TCTI	or directories for the Fapi metadata storages.

       fapi-profile(5) to determine the	cryptographic algorithms  and  parame-
       ters for	all keys and operations	of a specific TPM interaction like the
       name hash algorithm, the	asymmetric signature algorithm,	scheme and pa-
       rameters	and PCR	bank selection.

DESCRIPTION
       tss2_pcrextend(1)  - This command extends the data into the PCR listed.
       The parameter logData is	extended into the PCR log.  If the logData  is
       NULL,  only  the	 PCR extend takes place.  All PCRs currently active in
       the TPM are extended.

OPTIONS
       These are the available options:

        -x, --pcr=INTEGER:

       The PCR to extend.

        -i, --data=FILENAME or	- (for stdin):

	 The event data	to be extended.

        -l, --logData=FILENAME	or - (for stdin):

	 Contains a JSON representation	of data	to be  written	to  the	 PCR's
	 event log.  Optional parameter.

COMMON OPTIONS
       This  collection	of options are common to all tss2 programs and provide
       information that	many users may expect.

        -h, --help [man|no-man]: Display the tools manpage.  By  default,  it
	 attempts  to  invoke  the  manpager for the tool, however, on failure
	 will output a short tool summary.  This is the	same behavior  if  the
	 "man"	option argument	is specified, however if explicit "man"	is re-
	 quested, the tool will	provide	errors from man	 on  stderr.   If  the
	 "no-man"  option  if  specified, or the manpager fails, the short op-
	 tions will be output to stdout.

	 To successfully use the manpages feature requires the manpages	to  be
	 installed or on MANPATH, See man(1) for more details.

        -v,  --version:  Display version information for this tool, supported
	 tctis and exit.

EXAMPLE
	      tss2_pcrextend --pcr=16 --data=data.file --logData=logData.file

RETURNS
       0 on success or 1 on failure.
