NAME
SYNOPSIS
tss2_nvextend [OPTIONS]
SEE ALSO
fapi-config(5) to adjust Fapi parameters like the used cryptographic profile and TCTI or directories for the Fapi metadata storages.

DESCRIPTION
tss2_nvextend(1) - This command performs an extend operation on an NV index (i.e. an NV index that behaves similar to a PCR).
OPTIONS
These are the available options:
- •
- -i, --data=FILENAME or - (for stdin):
The data to be extended into the NV space.
- •
- -p, --nvPath=STRING:
Identifies the NV space to write.
- •
- -l, --logData=FILENAME or - (for stdin):
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_nvextend --nvPath=/nv/Owner/NvExtend --data=data.file --logData=logData.file
RETURNS
0 on success or 1 on failure.
