💖 NAME 💖

gnutls_pubkey_export_rsa_raw — bestie, it's an API function, and it's here to yank the raw RSA public key bits out of your pubkey 🦋

This is a page from the gnutls manual, and we're keeping every single detail, no cap.

✨ SYNOPSIS ✨

#include <gnutls/abstract.h>

int gnutls_pubkey_export_rsa_raw(gnutls_pubkey_t key, gnutls_datum_t *
m, gnutls_datum_t * e);

🎀 ARGUMENTS 🎀

  • gnutls_pubkey_t key — this one holds the certificate. It's the main character you're pulling the key material out of 👑
  • gnutls_datum_t * m — this is where the modulus is gonna live afterwards. Heads up: it may be NULL 🙈
  • gnutls_datum_t * e — and this one catches the public exponent. Also may be NULL 💅

🌸 DESCRIPTION 🌸

Okay so here's the vibe: this function exports the RSA public key's parameters that are chilling inside the given structure. Like, it goes in, grabs them, and hands them over.

The new parameters get allocated using gnutls_malloc() and then stored in the appropriate datum. So yes, that memory is yours now — it's giving "you own this, bestie" energy 🫶

And the iconic part: this function allows for NULL parameters since 3.4.1 ⭐ (so if you only want one of them, that's totally fine, lowkey convenient)

💜 RETURNS 💜

  • GNUTLS_E_SUCCESS on success 🎉
  • otherwise, a negative error code 😭 (iykyk — always check your return values, fr fr)

🦋 SINCE 🦋

3.3.0 — a classic, honestly. Been serving since day one 💅

Okay that's the whole page, every flag, every NULL, every copyright line, all of it — nothing skipped, periodt 💖
