gnutls_privkey_verify_seed(3)

💖 gnutls_privkey_verify_seed 💖

okay bestie, sit down, hydrate, and let me tell you about a little function from the gnutls manual (that's the manual name btw, we're in the gnutls section of the docs, page 3, the library-call girlies 🎀).

---

✨ NAME ✨

gnutls_privkey_verify_seed — it's an API function, and its whole personality is "prove it" 💅

---

🌸 SYNOPSIS 🌸

#include <gnutls/abstract.h>

int gnutls_privkey_verify_seed(gnutls_privkey_t key,
gnutls_digest_algorithm_t digest, const void * seed, size_t seed_size);

literally just one include and one call, no cap 🫶

---

🦋 ARGUMENTS 🦋

• gnutls_privkey_t key — should contain a gnutls_privkey_t type. it's the key we're interrogating, main character energy 👑
• gnutls_digest_algorithm_t digest — it contains the digest algorithm used for key generation (if applicable). note the "(if applicable)" bestie, we don't gatekeep 🎀
• const void * seed — the seed of the key to be checked with 🌱
• size_t seed_size — holds the size of seed. gotta know how big the seed is, it's giving measurements 📏

---

🔥 DESCRIPTION 🔥

This function will verify that the given private key was generated from the provided seed. that's it, that's the vibe check: was this key actually born from this seed, or is it lying to you 😭

---

⭐ RETURNS ⭐

In case of a verification failure GNUTLS_E_PRIVKEY_VERIFICATION_ERROR is returned, and zero or positive code on success. so like: zero-or-positive = we ate 💅, that specific error = not me getting caught lacking 🙈

---

🎀 SINCE 🎀

3.5.0 — vintage, but in a cute way 💜
