💖 gnutls_x509_sp..._rsa_pss_params(3) 💖

okay bestie so you're in the gnutls manual, and this lil page is all about one very specific function that pulls RSA-PSS params out of a SubjectPublicKeyInfo. yes it's a mouthful, no you're not dumb, the page title is literally truncated with ... because it's That Long. let's get into it 🫶

✨ NAME ✨

gnutls_x509_spki_get_rsa_pss_params — it's an API function, periodt.

✨ SYNOPSIS ✨

#include <gnutls/x509.h>

int gnutls_x509_spki_get_rsa_pss_params(gnutls_x509_spki_t spki,
gnutls_digest_algorithm_t * dig, unsigned int * salt_size);

like, you gotta include the header first, obviously 💅

✨ ARGUMENTS ✨

  • gnutls_x509_spki_t spki — the SubjectPublicKeyInfo structure. this is the thing you're interrogating, she's the main character here 👑
  • gnutls_digest_algorithm_t * dig — if it's non-NULL, it will hold the digest algorithm. if it's NULL, she simply does not get filled, and that's fine 🌸
  • unsigned int * salt_size — if it's non-NULL, it will hold the salt size. same deal, NULL means she stays empty, no shade 💜

✨ DESCRIPTION ✨

so what does this do? this function will get the public key algorithm parameters of RSA-PSS type. that's it. that's the whole job. she's a getter, she gets things, and she gets them correctly ✨

✨ RETURNS ✨

  • returns zero if the parameters are present ✨
  • or a negative value on error 😭
lowkey important: zero = good news, negative = something went wrong. don't flip those around bestie, i'm begging 🙈

✨ SINCE ✨

3.6.0 — she's been here since 3.6.0, an absolute icon of longevity 💖
