💖 gnutls_x509_crt_get_issuer 💖

okay bestie, this is a page from the gnutls manual, and it's about getting the issuer out of a certificate. yes, like, the who signed this of it all. let's go 🦋

✨ NAME ✨

gnutls_x509_crt_get_issuer — literally an API function, that's the whole name, slay

🌸 SYNOPSIS 🌸

#include <gnutls/x509.h>

int gnutls_x509_crt_get_issuer(gnutls_x509_crt_t cert, gnutls_x509_dn_t
*dn);

🎀 ARGUMENTS 🎀

  • gnutls_x509_crt_t cert — bestie this one should contain a gnutls_x509_crt_t type. that's it, that's the vibe.
  • gnutls_x509_dn_t * dn — this is your output variable, and it holds a pointer to a uint8_t DN. it's giving "results go here" 💅

👑 DESCRIPTION 👑

So what it does: it returns the Certificate's Issuer DN as a gnutls_x509_dn_t data type, which you can then decode using gnutls_x509_dn_get_rdn_ava(). adorable, right? 🫶

⚠️ okay IMPORTANT though: dn should be treated as constant. because it points into the cert object, you should not use dn after cert is deallocated. like, don't. that's undefined-ish chaos and we don't do that here 💀

🌈 RETURNS 🌈

Returns 0 on success, or an error code. that's the whole story, no notes ✨
