💖 gnutls_cipher_add_auth(3) 💖

okay bestie, so this one lives in the gnutls manual section — it's an API function, and yes it's exactly as niche and exactly as powerful as it sounds 🫶

✨ NAME ✨

gnutls_cipher_add_auth — API function, aka the little guy who does the "authenticate this please" job 🔥

🌸 SYNOPSIS 🌸

#include <gnutls/crypto.h>

int gnutls_cipher_add_auth(gnutls_cipher_hd_t handle, const void *
ptext, size_t ptext_size);

🎀 ARGUMENTS 🎀

  • gnutls_cipher_hd_t handle — it's a gnutls_cipher_hd_t type. that's the whole vibe. your handle, your main character 👑
  • const void * ptext — the data to be authenticated. the actual content getting the vibe check 💅
  • size_t ptext_size — the length of the data. how many bytes we're talking about, fr fr 📏

💫 DESCRIPTION 💫

So here's the tea: this function operates on authenticated encryption with associated data (AEAD) ciphers, and it authenticates the input data. that's it. that's the job. no encryption happening here, just authentication ✨

⚠️ bestie, listen — this function can only be called once, and it has to happen before any encryption operations. once. before. that's the rule and it's not negotiable 😭

🌈 RETURNS 🌈

Zero, or a negative error code on error. that's it. zero = slay, negative = something went wrong 💀

⭐ SINCE ⭐

3.0 — she's been around, she's a legacy icon 👑
