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 parameters for all keys  and
       operations  of  a  specific  TPM  interaction like the name hash algorithm, the asymmetric
       signature algorithm, scheme and parameters 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  requested,  the tool will provide errors from man on stderr.  If the “no-man”
         option if specified, or the manpager fails, the short options 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.
