GNUTLS_SRP_SET_CLIENT_CREDENTIALS_FUNCTION(3)

✨ NAME ✨

gnutls_srp_set_client_credentials_function — an API function, bestie 💅 (this one lives in the gnutls manual, section 3, iykyk)

---

🌸 SYNOPSIS 🌸

#include <gnutls/gnutls.h>

void
gnutls_srp_set_client_credentials_function(gnutls_srp_client_credentials_t
cred, gnutls_srp_client_credentials_function * func);

---

🎀 ARGUMENTS 🎀

• gnutls_srp_client_credentials_t cred — okay so this one is a gnutls_srp_server_credentials_t type. yes, fr, that's what it says, no cap 🙈
• gnutls_srp_client_credentials_function * func — the callback function, the little main character that does the actual work 🫶

---

🦋 DESCRIPTION 🦋

So here's the tea, bestie: this function lets you set a callback that goes and fetches the username and password for client SRP authentication. Like, instead of hardcoding your creds, you hand gnutls a lil function and it'll go ask it. Iconic behavior honestly. ✨

The callback's function form is:

int (*callback)(gnutls_session_t, char** username, char**password);

The username and password must be allocated using gnutls_malloc(). yes literally, that specific one, don't get cute with plain malloc 💀

The username should be an ASCII string or UTF-8 string. In case of a UTF-8 string it is recommended to be following the PRECIS framework for usernames (rfc8265). The password can be in ASCII format, or normalized using gnutls_utf8_password_normalize(). do with that info what you will, but those are the rules 👑

The callback function will be called once per handshake before the initial hello message is sent. so like, one shot, before the convo even starts 🌈

⚠️ The callback should not return a negative error code the second time it's called, since the handshake procedure will be aborted. not me warning you twice — it's literally in the spec, don't do it 🙅♀️

The callback function should return 0 on success. -1 indicates an error.

okay that's the whole page, you ate that 🍓 This was gnutls version 3.8.13, and the original page's title was gnutls_srp_set_...ntials_function(3) (yes the header truncates it, that's just how it prints, don't come for me 😭). bye bestie, go write a fire callback 💅✨
