tss2_nvwrite(1) General Commands Manual tss2_nvwrite(1) 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 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_nvwrite(1) - This command writes data to a "regular" (not pin, ex- tend 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 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_nvwrite --nvPath=/nv/Owner/myNV --data=data.file RETURNS 0 on success or 1 on failure.
