💅 pskc_set_key_algparm_chall_min — from the libpskc girlies

okay so bestie, welcome to pskc_set_key_algparm_chall_min(3), one of the many little gems living inside the libpskc manual. she's a setter, she's a vibe, she's here to make your ChallengeFormat behave. let's get into it 🎀

✨ NAME ✨

pskc_set_key_algparm_chall_min — literally just an API function, no cap. that's the whole name. slay.

🌸 SYNOPSIS 🌸

#include <pskc.h>

void pskc_set_key_algparm_chall_min(pskc_key_t * key, uint32_t
challmin);

that's it. that's the whole thing. two arguments, zero return value, all business. 💅

🦋 ARGUMENTS 🦋

  • pskc_key_t * key — your pskc_key_t handle, bestie. you get it from pskc_get_keypackage(), so don't just conjure one out of thin air, okay? 🫶
  • uint32_t challmin — the minimum challenge length you wanna set. that's the vibe check you're applying.

💖 DESCRIPTION 💖

so what does she actually do? she sets the PSKC KeyPackage Key AlgorithmParameters ChallengeFormat Min value. fancy name, very demure, very mindful.

here's the tea: this attribute defines the minimum size of the challenge accepted by the device for CR mode, and it MUST be included. like, mandatory mandatory. not optional. not "if you feel like it". it's giving required-field energy. 👑

and because context matters, the meaning of the number shifts depending on the Encoding attribute:

  • if Encoding is set to DECIMAL, HEXADECIMAL, or ALPHANUMERIC, then this value indicates the minimum number of digits/characters. ✨
  • if Encoding is set to BASE64 or BINARY, then this value indicates the minimum number of bytes of the unencoded value. 🔥

same number, different meaning, iykyk. don't mix them up or the math will simply not math.

⭐ SINCE ⭐

2.2.0 — she's been iconic since 2.2.0, we stan a long-running queen.
