✨ NAME ✨

gnutls_x509_crl_get_extension_data2 — okay bestie, this is an API function 💖 it lives in the gnutls manual and it's your girl for pulling extension data out of a CRL. iykyk 💅

🌸 SYNOPSIS 🌸

#include <gnutls/x509.h>

int gnutls_x509_crl_get_extension_data2(gnutls_x509_crl_t crl, unsigned
indx, gnutls_datum_t * data);

like. look at her. she's gorgeous. 🫶

🎀 ARGUMENTS 🎀

  • gnutls_x509_crl_t crl — this one should contain a gnutls_x509_crl_t type, no cap. it's the whole CRL you're digging around in 💖
  • unsigned indx — Specifies which extension OID to read. Use (0) to get the first one. yes literally zero. start at zero. not one. zero 🙈
  • gnutls_datum_t * data — will contain the extension DER-encoded data. so this is where the good stuff lands ✨

💜 DESCRIPTION 💜

This function will return the requested by the index extension data in the certificate revocation list. certificate revocation list, bestie, that's the CRL, we're in CRL territory 👑

The extension data will be allocated using gnutls_malloc(). so like, she allocates for you, that's the vibe 🌈

Use gnutls_x509_crt_get_extension_info() to extract the OID. yes the CRT one. not the CRL one. that's not a typo, that's just what the docs say, so write it down 📝

⭐ RETURNS ⭐

On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error code is returned. 😭

If you have reached the last extension available GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned. so when you're at the end, she tells you. that's your sign to stop looping 💀
