=head1 NAME
|
|
SSL_SESSION_get0_ticket,
|
SSL_SESSION_has_ticket, SSL_SESSION_get_ticket_lifetime_hint
|
- get details about the ticket associated with a session
|
|
=head1 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);
|
|
=head1 DESCRIPTION
|
|
SSL_SESSION_has_ticket() returns 1 if there is a Session Ticket associated with
|
this session, and 0 otherwise.
|
|
SSL_SESSION_get_ticket_lifetime_hint returns the lifetime hint in seconds
|
associated with the session ticket.
|
|
SSL_SESSION_get0_ticket obtains a pointer to the ticket associated with a
|
session. The length of the ticket is written to B<*len>. If B<tick> is non
|
NULL then a pointer to the ticket is written to B<*tick>. 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().
|
|
=head1 RETURN VALUES
|
|
SSL_SESSION_has_ticket() returns 1 if session ticket exists or 0 otherwise.
|
|
SSL_SESSION_get_ticket_lifetime_hint() returns the number of seconds.
