Dear All,
Openssl version used is 3.0.2 and TLS is 1.2
Currently in our product we are using "SSL_SESSION_get_id(SSL_get0_session((SSL
*) m_pSsl), nullptr)" to get the SSL Session ID(session is getting created
successfully).
But the session ID is coming as NULL(00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00).
Our server has been enabled with session caching using
"SSL_set_not_resumable_session_callback".
Please provide us inputs on do we need to use any other flavor of the like
SSL_SESSION_get0_id_context() instead of SSL_SESSION_get_id()
Regards,
Sethu V

Successful handshakes need not issue a non-empty session id. The server may
not support resumption, or may support only ticket-based resumption and have no
session cache.
Absence of a session id is NOT a failure, and your code must not require one.

Don't require a session id.
