ssl_ctx_set_timeout(3ssl) [bsd man page]

SSL_CTX_set_timeout(3SSL)					      OpenSSL						 SSL_CTX_set_timeout(3SSL)

NAME
SSL_CTX_set_timeout, SSL_CTX_get_timeout - manipulate timeout values for session caching SYNOPSIS
#include <openssl/ssl.h> long SSL_CTX_set_timeout(SSL_CTX *ctx, long t); long SSL_CTX_get_timeout(SSL_CTX *ctx); DESCRIPTION
SSL_CTX_set_timeout() sets the timeout for newly created sessions for ctx to t. The timeout value t must be given in seconds. SSL_CTX_get_timeout() returns the currently set timeout value for ctx. NOTES
Whenever a new session is created, it is assigned a maximum lifetime. This lifetime is specified by storing the creation time of the session and the timeout value valid at this time. If the actual time is later than creation time plus timeout, the session is not reused. 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. Expired sessions are removed from the internal session cache, whenever SSL_CTX_flush_sessions(3) is called, either directly by the application or automatically (see SSL_CTX_set_session_cache_mode(3)) 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. RETURN VALUES
SSL_CTX_set_timeout() returns the previously set timeout value. SSL_CTX_get_timeout() returns the currently set timeout value. SEE ALSO

SSL_SESSION_get_time(3SSL)					      OpenSSL						SSL_SESSION_get_time(3SSL)

NAME
SSL_SESSION_get_time, SSL_SESSION_set_time, SSL_SESSION_get_timeout, SSL_SESSION_set_timeout - retrieve and manipulate session time and timeout settings SYNOPSIS
#include <openssl/ssl.h> long SSL_SESSION_get_time(const SSL_SESSION *s); long SSL_SESSION_set_time(SSL_SESSION *s, long tm); long SSL_SESSION_get_timeout(const SSL_SESSION *s); long SSL_SESSION_set_timeout(SSL_SESSION *s, long tm); long SSL_get_time(const SSL_SESSION *s); long SSL_set_time(SSL_SESSION *s, long tm); long SSL_get_timeout(const SSL_SESSION *s); long SSL_set_timeout(SSL_SESSION *s, long tm); DESCRIPTION
SSL_SESSION_get_time() returns the time at which the session s was established. The time is given in seconds since the Epoch and therefore compatible to the time delivered by the time() call. SSL_SESSION_set_time() replaces the creation time of the session s with the chosen value tm. SSL_SESSION_get_timeout() returns the timeout value set for session s in seconds. SSL_SESSION_set_timeout() sets the timeout value for session s in seconds to tm. The SSL_get_time(), SSL_set_time(), SSL_get_timeout(), and SSL_set_timeout() functions are synonyms for the SSL_SESSION_*() counterparts. NOTES
Sessions are expired by examining the creation time and the timeout value. Both are set at creation time of the session to the actual time and the default timeout value at creation, respectively, as set by SSL_CTX_set_timeout(3). Using these functions it is possible to extend or shorten the lifetime of the session. RETURN VALUES
SSL_SESSION_get_time() and SSL_SESSION_get_timeout() return the currently valid values. SSL_SESSION_set_time() and SSL_SESSION_set_timeout() return 1 on success. If any of the function is passed the NULL pointer for the session s, 0 is returned. SEE ALSO
