💖 gnutls_x509_privkey_get_seed(3) 💖

okay bestie, sit down, we're reading a gnutls manpage together and honestly? it's giving ✨niche cryptographic lore✨. this one lives in the gnutls manual, and it's all about pulling the seed back out of a private key. yes, the literal origin story of your key. main character energy fr fr 🌱

---

🌸 NAME 🌸

gnutls_x509_privkey_get_seed — it's an API function, bestie, that's the whole vibe 💅

---

✨ SYNOPSIS ✨

#include <gnutls/x509.h>

int gnutls_x509_privkey_get_seed(gnutls_x509_privkey_t key,
gnutls_digest_algorithm_t * digest, void * seed, size_t * seed_size);

---

🎀 ARGUMENTS 🎀

• gnutls_x509_privkey_t key — this one should contain a gnutls_x509_privkey_t type. it's the key you're interrogating, the one you're asking "so... where did you come from?" 🕵️‍♀️
• gnutls_digest_algorithm_t * digest — if it's non-NULL, it will contain the digest algorithm that was used for key generation (if applicable). so like, if there's a digest to report, it goes here 🧾
• void * seed — where seed will be copied to. that's the destination, the lil home for your seed 🏠
• size_t * seed_size — originally holds the size of seed, and will be updated with the actual size. so it goes in as "here's how much room i have" and comes out as "here's how much i actually used". glow-up, honestly 💫

---

💜 DESCRIPTION 💜

this function will return the seed that was used to generate the given private key. that's it, that's the whole job — reverse-engineering the ~origin story~ of your key 🔮

but not me warning you: that function will succeed only if the key was generated as a provable key. no provable key? no seed. it's giving exclusive club, and not everyone has a membership card 🎟️

---

🔥 RETURNS 🔥

on success, GNUTLS_E_SUCCESS (0) is returned — slay, zero, we love a zero 🎉

otherwise, a negative error value. so if you see a negative number, that's the universe saying "no seed for you today" 😭
