🌸 NAME 🌸

okay bestie, this is the SSL_SESSION_HAS_TICKET(3ossl) manual page, and we're folding that whole manual-name moment in right at the top so we can get to the cute stuff 💅

the little function squad is:

  • SSL_SESSION_get0_ticket
  • SSL_SESSION_has_ticket
  • SSL_SESSION_get_ticket_lifetime_hint

and their collective mission? get details about the ticket associated with a session. periodt. ✨

✨ SYNOPSIS ✨

okay, here's the include and the exact signatures — copy these character-for-character, no improv:

#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);

🎀 DESCRIPTION 🎀

SSL_SESSION_has_ticket() — returns 1 if there is a Session Ticket associated with this session, and 0 otherwise. It's literally a vibe check for "ticket or no ticket" 💖

SSL_SESSION_get_ticket_lifetime_hint — returns the lifetime hint in seconds associated with the session ticket. The unit is seconds, bestie, keep that in mind.

SSL_SESSION_get0_ticket — obtains a pointer to the ticket associated with a session. The length of the ticket is written to *len. If tick is non NULL, then a pointer to the ticket is written to *tick.

🚨 okay important: the pointer is only valid while the connection is in use. The session (and hence the ticket pointer) may also become invalid as a result of a call to SSL_CTX_flush_sessions(). So do not go saving that pointer like it's a forever screenshotted text, because it is not.

💖 RETURN VALUES 💖

  • SSL_SESSION_has_ticket() — returns 1 if a session ticket exists, or 0 otherwise. It's giving binary, no cap.
  • SSL_SESSION_get_ticket_lifetime_hint() — returns the number of seconds. that's the whole return value, bestie.
