NAME
tss2_nvwrite(1) -
SYNOPSIS
tss2_nvwrite [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_nvwrite(1) - This command writes data to a “regular” (not pin, extend or counter) NV
index. Only the full index can be written, partial writes are not allowed. If the
provided data is smaller than the NV index’s size, then it is padded up with zero bytes at
the end.
OPTIONS
These are the available options:
• -i, --data=FILENAME or - (for stdin):
The data to write to the NV space.
• -p, --nvPath=STRING:
Identifies the NV space to write to.
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_nvwrite --nvPath=/nv/Owner/myNV --data=data.file
RETURNS
0 on success or 1 on failure.
