#include <openssl/ssl.h> long SSL_CTX_set_timeout(SSL_CTX *ctx, long t); long SSL_CTX_get_timeout(SSL_CTX *ctx);
SSL_CTX_get_timeout() returns the currently set timeout value for ctx.
Due to this realization, all sessions behave according to the timeout value valid at the time of the session negotiation. Changes of the timeout value do not affect already established sessions.
The expiration time of a single session can be modified using the SSL_SESSION_get_time(3) family of functions.
The default value for session timeout is decided on a per protocol basis, see SSL_get_default_timeout(3). All currently supported protocols have the same default timeout value of 300 seconds.
This timeout value is used as the ticket lifetime hint for stateless session tickets. It is also used as the timeout value within the ticket itself.
For TLSv1.3, RFC8446 limits transmission of this value to 1 week (604800 seconds).
For TLSv1.2, tickets generated during an initial handshake use the value as specified. Tickets generated during a resumed handshake have a value of 0 for the ticket lifetime hint.
SSL_CTX_get_timeout() returns the currently set timeout value.
