✨ gnutls_hex_encode2(3) ✨

okay bestie, welcome to the gnutls manual, page for gnutls_hex_encode2 💖 this one's a lil baby function but it's iconic in its own way, trust.

🌸 NAME 🌸

gnutls_hex_encode2 — it's an API function, periodt. that's the whole name, no crumbs.

🎀 SYNOPSIS 🎀

#include <gnutls/gnutls.h>

int gnutls_hex_encode2(const gnutls_datum_t * data, gnutls_datum_t *
result);

look at her. two args, one int return. she's giving "small but mighty" energy ngl 🫶

💅 ARGUMENTS 💅

  • const gnutls_datum_t * data — this is the raw data, bestie. the actual bytes you wanna hex-ify. it's const, so like, hands off, we're just reading, no touchy 🙈
  • gnutls_datum_t * result — this is where the glow-up lands: the result, in an allocated string. note the asterisk, she's a pointer, she gets filled in for you ✨

🦋 DESCRIPTION 🦋

so what does she DO? she takes the data you handed her and converts it to printable data using the hex encoding — the exact same hex encoding used in the PSK password files. iykyk 🔥

⚠️ important lil caveat, no cap: the size of the result does NOT include the null terminator. so don't go counting that \0 in your length math, she's not in the club 💀

⭐ RETURNS ⭐

GNUTLS_E_SUCCESS on success, bestie!! 🎉 and otherwise... a negative error code 😭 so like, if you see a negative number, something went wrong and you should go check your vibe (and your inputs). the way that error handling is literally mandatory here — do not skip it fr fr.
