💖 SSL_SESSION_HAS_TICKET 💖

okay bestie, welcome to SSL_SESSION_HAS_TICKET(3ossl) — the little trio of functions that spill the tea on the ticket chillin' inside your SSL session. it's giving "backstage pass peek" energy. let's go 🎟️✨

🌸 NAME 🌸

SSL_SESSION_get0_ticket, SSL_SESSION_has_ticket, SSL_SESSION_get_ticket_lifetime_hint — get the deets about the ticket that's associated with a session 🎀

✨ 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);

like, that's the whole entrance exam. three functions, one header, no cap 💅

🦋 DESCRIPTION 🦋

okay so first up:

  • SSL_SESSION_has_ticket() — returns 1 if there's a Session Ticket associated with this session, and 0 otherwise. simple as that, bestie. does it have a ticket or not, yes or no, periodt.

next:

  • SSL_SESSION_get_ticket_lifetime_hint — returns the lifetime hint, in seconds, associated with the session ticket. so like, how long is this ticket even valid for? it tells you. ⏳

and then the main character:

  • SSL_SESSION_get0_ticket — obtains a pointer to the ticket associated with a session. the length of the ticket gets written to *len. if tick is non NULL then a pointer to the ticket gets written to *tick.
🚨 okay listen, this part matters: that pointer is only valid while the connection is in use. and the session (and hence the ticket pointer) may also become invalid as a result of a call to SSL_CTX_flush_sessions(). so don't go holding onto it like it's your emotional support pointer, because it will ghost you 😭💀

👑 RETURN VALUES 👑

  • SSL_SESSION_has_ticket() returns 1 if a session ticket exists, or 0 otherwise. iconic binary behaviour, honestly 🌈
  • SSL_SESSION_get_ticket_lifetime_hint() returns the number of seconds. ⭐
