okay so you're on the SSL_SESSION_IS_RESUMABLE(3ossl) page, bestie — aka the manual page for SSL_SESSION_is_resumable. It’s giving tiny function, big “can I reuse this session?” energy. 💅

🌸 NAME 🌸

SSL_SESSION_is_resumable — determine whether an SSL_SESSION object can be used for resumption. Literally that’s the whole name vibe. ✨

🎀 SYNOPSIS 🎀

#include <openssl/ssl.h>

int SSL_SESSION_is_resumable(const SSL_SESSION *s);

🦋 DESCRIPTION 🦋

SSL_SESSION_is_resumable() determines whether an SSL_SESSION object can be used to resume a session or not. Returns 1 if it can or 0 if not. Note that attempting to resume with a non-resumable session will result in a full handshake.

So yeah: non-resumable session = full handshake, no shortcut, periodt. 😭

✨ RETURN VALUES ✨

SSL_SESSION_is_resumable() returns 1 if the session is resumable or 0 otherwise. That’s it, bestie — binary slay. 💖
