💖 SSL_CTX_SESSIONS 💖

okay so bestie, welcome to SSL_CTX_SESSIONS(3ossl) — it's an OpenSSL page and it's lowkey short but she is important, so let's get into it 🫶

✨ NAME ✨

SSL_CTX_sessions — your all-access pass to the internal session cache, no cap 🔑

🌸 SYNOPSIS 🌸

#include <openssl/ssl.h>

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

🦋 DESCRIPTION 🦋

okay so SSL_CTX_sessions() hands you back a pointer to the lhash databases that hold the internal session cache for ctx. that's it. that's the whole function. she's a one-trick pony and she ate 💅

🎀 NOTES 🎀

so the sessions chilling in the internal session cache live inside an LHASH(3) type database. and yeah, you can go straight into that database, like for searching and stuff. it's right there, it's giving open-door policy ✨

BUT. and this is the part where you need to pay attention bestie 😭 — in parallel, those same sessions also form a linked list, and that linked list is maintained completely separately from the LHASH(3) operations.

🚨 so the database must not be modified directly!! like, at all!! if you want to touch it you go through the SSL_CTX_add_session(3) family of functions, periodt. doing it by hand is not it, i'm literally begging you 🙈

⭐ RETURN VALUES ⭐

SSL_CTX_sessions() returns a pointer to the lhash of SSL_SESSION. iconic. 💖

okay that's the whole page bestie, you're basically an OpenSSL session cache expert now 🧚✨ this was OpenSSL 3.5.9, dated 2026-09-29, and it lives at SSL_CTX_SESSIONS(3ossl). go forth and do NOT modify that lhash directly, i'm watching 👀💜
