SSL_CTX_SESSIONS(3ossl)

📦 version 3.5.0, in opensuse-leap 16.0

💅 SSL_CTX_SESSIONS(3ossl)

okay so before we even start: this is an OpenSSL manual page, bestie. buckle up 🎀

✨ NAME ✨

SSL_CTX_sessions — access internal session cache

like, it literally hands you the internal session cache. that's the whole gig. 💖

✨ SYNOPSIS ✨

#include <openssl/ssl.h>

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

one function, one pointer, zero drama. we love a low-maintenance icon. 🌸

✨ DESCRIPTION ✨

So SSL_CTX_sessions() returns a pointer to the lhash databases holding the internal session cache for ctx. that's it. that's the function. she's a getter and she knows it. ✨

🦋 NOTES 🦋

okay this is the part where you actually pay attention, bestie, because there's a trap here 👀

The sessions chillin' in the internal session cache live in an LHASH(3) type database. You can directly access this database — for searching, for example. it's right there, it's open, it's giving open-bar energy. 🍓

BUT — and this is the big but — in parallel, the sessions also form a linked list which is maintained separately from the LHASH(3) operations. so...

the database must not be modified directly, because it's hooked up to that separate linked list. instead you use the SSL_CTX_add_session(3) family of functions. periodt. modifying it by hand is not the vibe and it WILL ruin the linked list's whole day. 😭

✨ RETURN VALUES ✨

SSL_CTX_sessions() returns a pointer to the lhash of SSL_SESSION. simple. clean. iconic. 👑
