✨ gnutls_encode_rs_value ✨

okay so bestie, we're deep in the gnutls manual (that's the GNU TLS library, she's iconic, she's everywhere) and today's main character is gnutls_encode_rs_value — an API function, no cap. let's get into it 💅

🌸 SYNOPSIS 🌸

#include <gnutls/crypto.h>

int gnutls_encode_rs_value(gnutls_datum_t * sig_value, const
       gnutls_datum_t * r, const gnutls_datum_t * s);

🎀 ARGUMENTS 🎀

  • gnutls_datum_t * sig_value — this one's the lil container that will hold a Dss-Sig-Value DER encoded structure. she's the output girlie, she gets filled in 🫶
  • const gnutls_datum_t * r — must contain the r value. like, it HAS to, that's the whole vibe 🔥
  • const gnutls_datum_t * s — must contain the s value. same energy, different letter 💖

🦋 DESCRIPTION 🦋

so what does she DO? this function will encode the r and s values you hand her into a Dss-Sig-Value structure — which is the format used for DSA and ECDSA signatures. it's giving "put the two halves together so the rest of the world can read them" 💫

heads up bestie: the output value should be deallocated using gnutls_free(). do NOT forget, or that memory is gonna linger like an ex who won't stop watching your stories 😭

⭐ RETURNS ⭐

on success, GNUTLS_E_SUCCESS (0) is returned — slay 🎉

otherwise? an error code comes back. not slay, but informative 💀

🌈 SINCE 🌈

3.6.0 — she's been around, she's a veteran, respect her 👑
