       See SSL_CTX_set_session_id_context(3) for further details on session ID contexts.

       SSL_SESSION_get0_id_context() returns the ID context associated with the SSL/TLS session s. The length of
       the ID context is written to *len if len is not NULL.

       The value returned is a pointer to an object maintained within s and should not be released.

       SSL_SESSION_set1_id_context() takes a copy of the provided ID context given in sid_ctx and associates it
       with the session s. The length of the ID context is given by sid_ctx_len which must not exceed
       SSL_MAX_SID_CTX_LENGTH bytes.

       The SSL_SESSION_get0_id_context() function was added in OpenSSL 1.1.0.
