💅 pskc_set_key_algparm_chall_max(3) — a libpskc moment

okay bestie, so this one lives in libpskc, and it's genuinely just a little setter function. nothing scary. let's get into it 🫶

✨ NAME ✨

pskc_set_key_algparm_chall_max — it's an API function, that's the whole vibe 💖

🌸 SYNOPSIS 🌸

#include <pskc.h>

void pskc_set_key_algparm_chall_max(pskc_key_t * key, uint32_t
challmax);

like, literally two things in, nothing out — void, she returns nothing, she's lowkey humble about it 👑

🎀 ARGUMENTS 🎀

  • pskc_key_t * key — a pskc_key_t handle, and you get it from pskc_get_keypackage(). that's the plug, that's where it comes from 🔌
  • uint32_t challmax — the maximum challenge length to set. the number you're handing over, cute and unsigned ✨

💜 DESCRIPTION 💜

so what this actually does: it sets the PSKC KeyPackage Key AlgorithmParameters ChallengeFormat Max value. yes that's a mouthful, no I did not make it up 😭

this attribute defines the maximum size of the challenge accepted by the device for CR mode — and bestie, it MUST be included. not optional. mandatory main character requirement, periodt 💅

and here's the part where it depends on the Encoding attribute, so pay attention:

  • if Encoding is set to DECIMAL, HEXADECIMAL, or ALPHANUMERIC, this value indicates the maximum number of digits/characters 🔢
  • if Encoding is set to BASE64 or BINARY, this value indicates the maximum number of bytes of the unencoded value 🧊

same field, different unit depending on encoding — it's giving "context is everything" ngl 🦋

⭐ SINCE ⭐

2.2.0 — she's been around a minute, an icon of her era 👑
