✨ gnutls_x509_tlsfeatures_check_crt ✨

okay bestie, welcome to the gnutls manual — yes that's the manual name, we're in the gnutls house now 🏠💖 This one's an API function, so it's giving library-girl energy, not command-line-girl energy. Still iconic tho.

🌸 NAME 🌸

gnutls_x509_tlsfeatures_check_crt — literally just an API function, that's the whole vibe 💅

🎀 SYNOPSIS 🎀

#include <gnutls/x509.h>

unsigned gnutls_x509_tlsfeatures_check_crt(gnutls_x509_tlsfeatures_t
feat, gnutls_x509_crt_t cert);

like. she's a function. she takes two things. she returns an unsigned. no cap. 🦋

💜 ARGUMENTS 💜

  • gnutls_x509_tlsfeatures_t feat — a whole set of TLSFeatures, like a little squad of features 🫶
  • gnutls_x509_crt_t cert — the certificate that's getting checked, she's the one on trial bestie 😭

🌈 DESCRIPTION 🌈

so what this function DOES, fr fr: it takes that certificate you handed it and checks it against the TLSFeatures set living in feat, and it does that using the RFC7633 p.4.2.2 rules. (yes, an actual RFC, an actual page number, we stay precise here 👑)

and the check itself? it's checking whether the certificate contains the features in feat — or a superset of them. so like, extra features are fine, she's flexible, she just needs at least everything in feat to show up. periodt. ✨

⭐ RETURNS ⭐

  • non-zero if the certificate you provided complies 💚
  • zero otherwise 💀

that's it, that's the whole verdict. no in-between, no "it's complicated".

🦋 SINCE 🦋
