💖 gnutls_hmac(3) 💖

okay bestie, sit DOWN, because this one is from the gnutls manual and it's literally the little function that does the HMAC thing. you're gonna eat this up.

✨ NAME ✨

gnutls_hmac — an API function, periodt. it's giving "one job, done well" energy 💅

🎀 SYNOPSIS 🎀

#include <gnutls/crypto.h>

int gnutls_hmac(gnutls_hmac_hd_t handle, const void * ptext, size_t
ptext_len);

look at her. three little arguments. so unbothered. so iconic. 🦋

🌸 ARGUMENTS 🌸

  • gnutls_hmac_hd_t handle — bestie this is a gnutls_hmac_hd_t type. that's the whole description. it's a handle, it holds your whole situation together 🫶
  • const void * ptext — the data to hash. the actual tea. the stuff you want mushed into a digest ☕
  • size_t ptext_len — the length of data to hash. yes ma'am, we need to know how much data, we are not out here guessing byte counts 🔥

💜 DESCRIPTION 💜

so what does she DO? she will hash the given data using the algorithm specified by the context. that's it. that's the whole vibe. the context already knows which algorithm you picked (because you picked it when you set the handle up, duh), and this function just takes your data and runs it through. no cap, that's literally all ✨

⭐ RETURNS ⭐

Zero or a negative error code on error. so: 0 means slay, anything negative means something went sideways 😭 always check her, fr fr.

🌈 SINCE 🌈

2.10.0 — she's been around since 2.10.0, an absolute veteran, a legend in these streets 👑
