💖 gnutls_session_enable_compatibility_mode(3) — the gnutls manual, but make it make sense

okay bestie, sit down, we're reading a gnutls man page together and honestly? this one is giving "I'm about to make your TLS slightly less safe on purpose" 💅. It lives in the gnutls manual section 3, and the whole vibe is "maximum compatibility, minimum vibes".

✨ NAME ✨

gnutls_session_enable_compatibility_mode — an API function, and yeah, the name is a mouthful, we move anyway 🫶

🌸 SYNOPSIS 🌸

#include <gnutls/gnutls.h>

void gnutls_session_enable_compatibility_mode(gnutls_session_t session);

not me showing you the include first because that's just how it's done, iykyk ✨

🎀 ARGUMENTS 🎀

  • gnutls_session_t session — bestie it's a gnutls_session_t type. that's it, that's the arg, she's simple and she knows what she wants 💖

💅 DESCRIPTION 💅

so this function? it lets you disable certain (security) features in TLS so you can keep maximum compatibility with clients that are, respectfully, buggy. 💀

and because you're literally trading away security here — several trade-offs get enabled at once — the function will report them through the audit subsystem if they're required. so it's not sneaky, it's just… a lot. 🙈

normally only servers that need maximum compatibility with literally everything out there need to call this function. if that's not you, walk away, queen. 👑

⚠️ note that this function must be called after any call to gnutls_priority functions. order matters, no cap.

⭐ SINCE ⭐

2.1.4 — old money, been here since forever 🌈
