💖 SSL_CTX_SESSIONS 💖

okay bestie, welcome to the OpenSSL manual page for SSL_CTX_sessions — yes that's a <pink>3SSL</pink> section-3 page, we're in the library docs now, very serious, very caffeinated ✨

🌸 NAME 🌸

SSL_CTX_sessions — get at that internal session cache, no cap 🫶

✨ SYNOPSIS ✨

#include <openssl/ssl.h>

LHASH_OF(SSL_SESSION) *SSL_CTX_sessions(SSL_CTX *ctx);

so it's literally one function, one include, and it hands you a pointer. slay.

🦋 DESCRIPTION 🦋

So SSL_CTX_sessions() returns a pointer to the lhash databases that contain the internal session cache for ctx. that's it. that's the whole vibe. one pointer, whole cache. iconic 💅

👑 NOTES 👑

okay so this is the part you actually need, listen up 🎀

  • the sessions in the internal session cache live inside an LHASH(3) type database. and because it's just there, you can directly access this database — like, for searching and stuff. iykyk 🔍
  • but — and this is the big one — in parallel, the sessions also form a linked list that's maintained separately from the LHASH(3) operations.
⚠️ bestie do NOT modify that database directly. like, at all. the link list and the lhash gotta stay in sync, and if you go poking at it yourself you're gonna break the whole thing 😭 you modify it by using the SSL_CTX_add_session(3) family of functions. that's the move. periodt.

🌈 RETURN VALUES 🌈

SSL_CTX_sessions() returns a pointer to the lhash of SSL_SESSION. simple. clean. obsessed. ✨
