✨ gnutls_x509_cr...ature_algorithm(3) ✨

okay bestie, gather round 💖 this one lives in the gnutls manual (yes, the big one), and it's genuinely such a useful little function. no cap.

🌸 NAME 🌸

gnutls_x509_crq_get_signature_algorithm — it's an API function, periodt.

🎀 SYNOPSIS 🎀

#include <gnutls/x509.h>

int gnutls_x509_crq_get_signature_algorithm(gnutls_x509_crq_t crq);

🦋 ARGUMENTS 🦋

  • gnutls_x509_crq_t crq — this one "should contain a gnutls_x509_cr_t type". yes literally that's what it says, i'm not making it up 🙈

💅 DESCRIPTION 💅

so this function hands you back a value from the gnutls_sign_algorithm_t enumeration — and that value is the signature algorithm that was used to sign this certificate request. that's the whole vibe. it's giving "who signed this crq and with what" 🔥

now here's the iconic part: since 3.6.0 this function never returns a negative error code. not once. error cases and unknown/unsupported signature algorithms all get mapped to GNUTLS_SIGN_UNKNOWN. so like, no sad little negative numbers coming back to ruin your day — just GNUTLS_SIGN_UNKNOWN doing its best 🫶

⭐ RETURNS ⭐

a gnutls_sign_algorithm_t value. that's it, that's the return 💜

🌈 SINCE 🌈

3.4.0 — it's been around a while, an elder icon 👑
