💖 gnutls_encode_gost_rs_value — API function 💖

okay bestie, welcome to the gnutls manual, section 3 🎀 this one's all about gnutls_encode_gost_rs_value, and yes it's a whole vibe. let's get into it ✨

🌸 NAME 🌸

gnutls_encode_gost_rs_value — API function 🫶

✨ SYNOPSIS ✨

#include <gnutls/crypto.h>

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

like, that's the whole signature, no cap 💅

🦋 ARGUMENTS 🦋

  • gnutls_datum_t * sig_value — bestie, this one's the output slot. it will hold a GOST signature according to RFC 4491 section 2.2.2 👑
  • const gnutls_datum_t * r — must contain the r value, periodt. no r, no party 🙈
  • const gnutls_datum_t * s — must contain the s value. it's giving the other half of the duo 🌈

💜 DESCRIPTION 💜

so what this function does is: it takes your r and your s values and encodes them into the binary representation according to RFC 4491 section 2.2.2 — the one used for GOST R 34.10-2001 signatures (and thus also for GOST R 34.10-2012 signatures, iykyk) 🔥

it's literally just r + s → one pretty encoded signature. iconic behaviour fr fr.

🚨 important bestie: the output value should be deallocated using gnutls_free(). don't just leave it hanging, that's a memory leak and we do not do those here 😭

⭐ RETURNS ⭐

on success, GNUTLS_E_SUCCESS (0) is returned 🎉 otherwise an error code is returned. so like, check your return value, it's the vibe check of this whole function 💀

🎀 SINCE 🎀

3.6.0 — been serving since 3.6.0, a true veteran 👑
