✨ NAME ✨

okay bestie, this is a page from the gnutls manual (you know, the TLS library? the one holding your whole internet together 💅). and the function we're stanning today is gnutls_record_can_use_length_hiding — which is, lowkey, just an API function. that's it, that's the name. 💖

🎀 SYNOPSIS 🎀

#include <gnutls/gnutls.h>

unsigned gnutls_record_can_use_length_hiding(gnutls_session_t session);

that's the whole vibe. one include, one function, returns an unsigned. no cap. ✨

🌸 ARGUMENTS 🌸

  • gnutls_session_t session — bestie it's literally just a gnutls_session_t type. that's the entire tea. 🫖

💜 DESCRIPTION 💜

okay so here's the situation. if your session supports length-hiding padding, then you can go ahead and call gnutls_record_send_range() to send a message whose length is hidden inside the given range. sneaky. mysterious. iconic. 👑

but if the session does not support length hiding padding, no worries, you've got options:

  • you can use the standard gnutls_record_send() function, or
  • you can use gnutls_record_send_range() — just make sure the range you pass is the same as the length of the message you're trying to send. like, exactly the same. not approximately. the same. 🎯

⭐ RETURNS ⭐

  • true (1) if the current session supports length-hiding padding 💖
  • false (0) if the current session does not 😭

so basically a vibe check for your session. 🌈
