💖 HMAC(1) 💖

Bestie, welcome to the hmac manual page. She lives in section 1, the User Commands girlies, and her name is hmac ✨ (the header yells HMAC in all caps, the command is lowercase hmac — she contains multitudes, it's giving duality 💅).

🌸 NAME 🌸

hmac — Runs TPM2_Hmac 🎀

🦋 DESCRIPTION 🦋

Okay so. First line of the description. Sit down, hydrate, breathe:

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

That's it. That's the opener. Not a valid option, bestie. She said it once, she'll say it again later, we love a consistent queen 💀

Then, simply:

hmac

Runs TPM2_HMAC. That's the whole vibe. Short, sweet, iconic, no notes. 👑

Here's everything she takes, exactly as she says it:

  • -hk — key handle 🔑
  • -pwdk — password for key (default empty)
  • [-halg (sha1, sha256, sha384) (default sha256)] — the hash algorithm, defaulting to sha256 ✨
  • -if — input file to be HMACed
  • -ic — data string to be HMACed
  • [-os hmac file name (default do not save)] — hmac file name, and if you don't pass it, bestie, she does not save 🫶
  • -se[0-2] — session handle / attributes (default PWAP)
    • 01 — continue

🙈 and then… she says it AGAIN 🙈

No literally, the whole thing repeats. I'm not editing her, I'm not judging her, I'm just reporting the facts fr fr:

--version is not a valid option
hmac

Runs TPM2_HMAC

  • -hk — key handle 🔑
  • -pwdk — password for key (default empty)
  • [-halg (sha1, sha256, sha384) (default sha256)] — again with the sha256 default 💖
  • -if — input file to be HMACed
  • -ic — data string to be HMACed
  • [-os hmac file name (default do not save)] — again, no name = no save
  • -se[0-2] — session handle / attributes (default PWAP)
    • 01 — continue

Same energy, second act, she's committed to the bit and honestly? We respect it. 🌈
