tss2_pcrextend1

Usage

Overview

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.

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.

Examples

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

Returns

0 on success or 1 on failure.
