SSL_SESSION_REUSED(3ossl)

📦 version 3.5.0, in opensuse-leap 16.0

💅 SSL_SESSION_REUSED (3ossl) — the OpenSSL glow-up ✨

okay so bestie, you're poking around in the OpenSSL man pages (the 3ossl section, iconic of you) and you found this little cutie: SSL_session_reused — it's the function that tells you whether the handshake you just did was a reuse situation or a fresh new thing. 🎀

🌸 NAME

SSL_session_reused — query whether a reused session was negotiated during handshake

like literally that's the whole vibe check of this page: was this session reused or not? 🦋

✨ SYNOPSIS

#include <openssl/ssl.h>

int SSL_session_reused(const SSL *ssl);

she takes one const SSL * pointer and hands you back an int. no cap, that's it. 🫶

💖 DESCRIPTION

Query whether a reused session was negotiated during the handshake.

that's the tea, that's the assignment. you're asking your SSL object, "bestie, did we reuse a session or not?" 👑

💫 NOTES

okay so here's the lore 🌈 — during the negotiation, a client can propose to reuse a session. then the server goes and looks up that session in its cache. and if both client and server agree on the session, it will be reused, and a flag gets set that can be queried by the application. that's the flag you're checking with this function. slay, honestly. 💅

🔥 RETURN VALUES

the following return values can occur:

  • 0 — a new session was negotiated. fresh out the box, brand new, main character debut energy ✨
  • 1 — a session was reused. she's a returning icon, we've seen her before 💖
