💖 gnutls_hex_decode2(3) 💖

okay bestie, welcome to the gnutls manual — this one's a little function page and it's honestly so useful. sit with me for a sec 🫶

✨ NAME ✨

gnutls_hex_decode2 — it's an API function, and its whole job is turning hex back into actual bytes. the glow-up from hex to raw data, if you will 💅

🌈 SYNOPSIS 🌈

#include <gnutls/gnutls.h>

int gnutls_hex_decode2(const gnutls_datum_t * hex_data, gnutls_datum_t *
result);

like, that's it. two args, one int coming back at you. no cap. ✨

🎀 ARGUMENTS 🎀

  • const gnutls_datum_t * hex_data — this is the encoded data, i.e. the hex string situation you're handing over. it's const, so don't even think about touching it, she's read-only 💅
  • gnutls_datum_t * result — and this is where the decoded output lands, in an allocated string. it's giving "here's your present, it's been malloc'd" 🎁

🦋 DESCRIPTION 🦋

so basically: this function decodes the encoded data you give it, using the hex encoding used by PSK password files. that's the specific flavour of hex we're talking about here, not just any hex-adjacent vibe. it decodes, it fills in your result, and it moves on with its life. iconic behaviour, truly. ✨

👑 RETURNS 👑

  • GNUTLS_E_PARSING_ERROR — this is what you get when the hex data is invalid. the vibe check failed. 💀
  • 0 — success, babe. we ate. 🔥
