💖 gnutls_encode_ber_digest_info ✨

okay bestie, welcome to the gnutls manual, page gnutls_encode_ber_digest_info(3) 🎀. this one's a lil crypto snack and it's honestly so useful, let's get into it 🫶

🌸 NAME 🌸

gnutls_encode_ber_digest_info — an API function, and yes she's the one who turns your digest into a proper RSA PKCS1 1.5 DigestInfo situation 💅

✨ SYNOPSIS ✨

#include <gnutls/crypto.h>

int gnutls_encode_ber_digest_info(gnutls_digest_algorithm_t hash, const
gnutls_datum_t * digest, gnutls_datum_t * output);

🎀 ARGUMENTS 🎀

  • gnutls_digest_algorithm_t hash — the hash algorithm that was used to get the digest, like, which flavor of hash we're working with 🔍
  • const gnutls_datum_t * digest — must contain the digest data. it literally has to have it, no empty vibes allowed 🙈
  • gnutls_datum_t * output — will contain the allocated DigestInfo BER encoded data. she's giving allocated, she's giving BER encoded, main character energy fr fr 👑

🦋 DESCRIPTION 🦋

so what this function does is: it takes the digest data you handed it, plus its algorithm, and encodes them both into an RSA PKCS1 1.5 DigestInfo structure. that's it, that's the whole glow-up ✨ no cap.

💖 RETURNS 💖

on success, GNUTLS_E_SUCCESS (0) is returned 🎉 otherwise an error code comes back instead, and you'll be like 😭 but that's just how it goes.

⭐ SINCE ⭐

3.5.0 — she's been iconic for a minute, iykyk 💅
