tss2_nvextend(1)

🦋 NAME 🦋

okay so welcome to the General Commands Manual page for tss2_nvextend(1) — yes, the NAME line is literally tss2_nvextend(1) -, and this is the command we’re talking about, bestie. 💅

✨ SYNOPSIS ✨

tss2_nvextend [OPTIONS]

🔭 SEE ALSO 🔭

• fapi-config(5) — use this to adjust Fapi parameters like the used cryptographic profile and TCTI or directories for the Fapi metadata storages. 🫶
• fapi-profile(5) — use this 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_nvextend(1) performs an extend operation on an NV index — and yes, that means an NV index that behaves similar to a PCR. It’s giving “PCR energy, but make it NV.” ✨

🎀 OPTIONS 🎀

These are the available options, bestie:

• -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 tool’s 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 is 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. No cap. ✅
