💖 gnutls_x509_crq_get_subject_alt_othername_oid(3) 💖

okay bestie, welcome to the gnutls manual, section 3 🎀. This one's a whole function deep-dive and honestly it's giving "certificate request archaeology" and I'm obsessed.

✨ NAME ✨

gnutls_x509_crq_get_subject_alt_othername_oid — it's an API function, bestie. That's the whole name, no notes. 💅

🌸 SYNOPSIS 🌸

okay so first you gotta pull in the header, like this:

#include <gnutls/x509.h>

and then the actual call, look at her:

int gnutls_x509_crq_get_subject_alt_othername_oid(gnutls_x509_crq_t crq,
unsigned int seq, void * ret, size_t * ret_size);

four args, one int coming back. she's tidy. she's iconic. 🦋

💜 ARGUMENTS 💜

  • gnutls_x509_crq_t crq — should contain a gnutls_x509_crq_t type. that's the certificate request you're digging through, no cap.
  • unsigned int seq — specifies the sequence number of the alt name (0 for the first one, 1 for the second etc.). zero-indexed, like a real one 💅.
  • void * ret — is the place where the otherName OID will be copied to. it's the destination, the lil landing spot, the home for your OID 🏠✨
  • size_t * ret_size — holds the size of ret. so like, how much room your destination has. important. do not skip her. 🫶

🎀 DESCRIPTION 🎀

This function will extract the type OID of an otherName Subject Alternative Name, contained in the given certificate, and return the type as an enumerated element.

lowkey important: This function is only useful if gnutls_x509_crq_get_subject_alt_name() returned GNUTLS_SAN_OTHERNAME. like, if it didn't, you're knocking on the wrong door bestie 😭

🔥 RETURNS 🔥

the alternative subject name type on success, one of the enumerated gnutls_x509_subject_alt_name_t. ⭐

For supported OIDs, it will return one of the virtual (GNUTLS_SAN_OTHERNAME_*) types, e.g. GNUTLS_SAN_OTHERNAME_XMPP, and GNUTLS_SAN_OTHERNAME for unknown OIDs. so like, if she knows the OID she'll give you the fancy specific name, and if she doesn't she just goes GNUTLS_SAN_OTHERNAME and shrugs 🤷♀️

It will return GNUTLS_E_SHORT_MEMORY_BUFFER if ret_size is not large enough to hold the value. In that case ret_size will be updated with the required size. so she's not gonna just fail silently — she tells you exactly how much room you should've given her. queen behaviour 👑

If the certificate does not have an Alternative name with the specified sequence number and with the otherName type then GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE is returned. it's just not there, babe. 💀

🦋 SINCE 🦋

2.8.0 — she's been around since 2.8.0, an elder. respect her. 🙇♀️
