gnutls_x509_crt_get_pk_algorithm(3)

💖 gnutls_x509_crt_get_pk_algorithm — the gnutls manual, bestie edition 💖

okay so you're reading the gnutls manual page for gnutls_x509_crt_get_pk_algorithm(3) and honestly? iconic choice. let's get into it 🎀

---

✨ NAME ✨

gnutls_x509_crt_get_pk_algorithm — it's an API function, bestie. that's the whole name. short, sweet, slays. 💅

---

🌸 SYNOPSIS 🌸

#include <gnutls/x509.h>

int gnutls_x509_crt_get_pk_algorithm(gnutls_x509_crt_t cert, unsigned
int * bits);

like yes, she takes two args and returns an int. we love a simple signature, no notes. 🦋

---

🫶 ARGUMENTS 🫶

• gnutls_x509_crt_t cert — this one should contain a gnutls_x509_crt_t type. that's it, that's the vibe check. she's your certificate, hand her over. 🌈
• unsigned int * bits — if bits is non null it's gonna hold the size of the parameters' in bits. so like, a pointer, and if you pass it she fills it in. ✨

---

👑 DESCRIPTION 👑

so what does she actually do? this function will return the public key algorithm of an X.509 certificate. periodt. 🔥

and if bits is non null, it should have enough size to hold the parameters size in bits. important, don't skip this: for RSA the bits returned is the modulus. for DSA the bits returned are of the public exponent. different keys, different meanings, no cap. 💀

unknown/unsupported algorithms are mapped to GNUTLS_PK_UNKNOWN. she doesn't guess, she doesn't improvise — she just says "idk her" and moves on. 🙈

---

⭐ RETURNS ⭐

on success you get a member of the gnutls_pk_algorithm_t enumeration. 🎉

or, if things went sideways, a negative error code on error. so like, check your return value, bestie, don't just assume. 😭
