💖 gnutls_tdb_set_verify_func(3) 💖

okay bestie, welcome to the gnutls manual, page gnutls_tdb_set_verify_func(3). sit down, hydrate, and let's get into it 🫶

✨ NAME ✨

gnutls_tdb_set_verify_func — API function. that's it, that's the name, short and iconic 💅

🌸 SYNOPSIS 🌸

#include <gnutls/gnutls.h>

void gnutls_tdb_set_verify_func(gnutls_tdb_t tdb, gnutls_tdb_verify_func verify);

🎀 ARGUMENTS 🎀

  • gnutls_tdb_t tdb — the trust storage. yes, the whole vibe holder 🗄️
  • gnutls_tdb_verify_func verify — the verification function. the little guy that does the actual checking ✨

🦋 DESCRIPTION 🦋

so what this function does is, it associates a retrieval function with the trust storage structure. like, you're setting up the trust storage and telling it "hey, when you need to verify something, use this function, mwah 💋".

and the function you hand over has to be in this exact form:

int gnutls_tdb_verify_func(const char* db_name, const char* host, const char* service, const gnutls_datum_t* pubkey);

okay now listen closely because this part is important, no cap 👑

your verify function should return:

  • zero on a match 🎉
  • GNUTLS_E_CERTIFICATE_KEY_MISMATCH if there is a mismatch 💀
  • any other negative error code otherwise

and bestie — the db_name is the one you use to pass any private data to this function. that's literally its whole job. iykyk 🙈
