💅 SSL_SESSION_HAS_TICKET — bestie, let's talk tickets ✨

okay so this is a page from the OpenSSL manual, section 3SSL, and it's all about peeking at the Session Ticket that's chilling inside your SSL session. no cap, it's a short one, but it's giving "tiny but essential" energy. 🎀

🌸 NAME 🌸

SSL_SESSION_get0_ticket, SSL_SESSION_has_ticket, SSL_SESSION_get_ticket_lifetime_hint — literally just "get details about the ticket associated with a session". that's the whole vibe. 🎫✨

✨ SYNOPSIS ✨

#include <openssl/ssl.h>

int SSL_SESSION_has_ticket(const SSL_SESSION *s);
unsigned long SSL_SESSION_get_ticket_lifetime_hint(const SSL_SESSION *s);
void SSL_SESSION_get0_ticket(const SSL_SESSION *s, const unsigned char **tick,
                             size_t *len);

look at those signatures. clean. three little functions. precious. 🫶

💖 DESCRIPTION 💖

so here's the tea on each one:

  • SSL_SESSION_has_ticket() — returns 1 if there's a Session Ticket associated with this session, and 0 otherwise. it's literally just the vibe check: does the ticket exist or not. ✅ / ❌
  • SSL_SESSION_get_ticket_lifetime_hint — returns the lifetime hint, in seconds, associated with the session ticket. (yes bestie, the manpage really does write it without the () at the end here. iconic of it. we're keeping it exactly as written. 💀)
  • SSL_SESSION_get0_ticket — this one obtains a pointer to the ticket associated with a session. the length of the ticket gets written to *len. and if tick is non-NULL, then a pointer to the ticket is written to *tick.

now listen, this part is important so I need you paying attention 👀 — that pointer is only valid while the connection is in use. do not go stashing it in your backpack and walking away with it. and the session (and hence the ticket pointer) may also become invalid as a result of a call to SSL_CTX_flush_sessions(). so like... use it while you're in the room, or it's gone. periodt. 💀

🔥 RETURN VALUES 🔥

  • SSL_SESSION_has_ticket() returns 1 if session ticket exists, or 0 otherwise. yes or no. no in-between. slay. 👑
  • SSL_SESSION_get_ticket_lifetime_hint() returns the number of seconds. that's it, that's the return value. ⏱️
