💖 NAME 💖

nvreadlock — Runs TPM2_NV_ReadLock

okay so bestie, welcome to the nvreadlock(1) page, living in the User Commands section of your manual, and it is exactly one job: it runs TPM2_NV_ReadLock. that's the whole vibe. 💅

🎀 DESCRIPTION 🎀

no cap, the description section here is giving "raw output, no filter," so let's just look at it together and I'll walk you through every crumb. 🍓

--version-string=v1045 is not a valid option

nvreadlock

Runs TPM2_NV_ReadLock

       [-hia hierarchy authorization (o, p)(default index
       authorization)] -ha NV index handle -pwdn password for NV index
       (default empty)

-se[0-2] session handle / attributes (default PWAP)

       01 continue

not me reading this like a text from my bestie — let's decode the parts one by one, fr fr:

  • nvreadlock — the command itself, and it Runs TPM2_NV_ReadLock. that's it. that's the job. main character energy. 👑
  • -hia — hierarchy authorization. it takes (o, p), and the default is index authorization. 🌸
  • -ha — the NV index handle. you gotta tell it which handle, bestie.
  • -pwdn — password for NV index, and the default is empty. 🫶
  • -se[0-2] — session handle / attributes, and the default is PWAP.
  • 01 continue — literally that, 01 continue. 💀

and then — because the universe loves a plot twist — the page says it again, with one tiny difference:

--version is not a valid option

nvreadlock

Runs TPM2_NV_ReadLock

       [-hia hierarchy authorization (o, p)(default index
       authorization)] -ha NV index handle -pwdn password for NV index
       (default empty)

-se[0-2] session handle / attributes (default PWAP)

       01 continue

so yeah: --version-string=v1045 is not a valid option shows up in the first pass, and --version is not a valid option shows up in the second. both of those lines are straight-up telling you those flags are not valid options, no notes, periodt. 🙈

heads up bestie — those two "not a valid option" lines are literally in the page, so don't come for me, I'm just the messenger 💖

okay and that's a wrap! this whole thing came from the nvreadlock page, dated July 2017, sitting pretty under NVREADLOCK(1). bye bestie, slay your TPM reads 💜🦋🌸
