I am trying to reuse SSL_SESSION as below, it works fine when I use TLSv1_2_client_method() to create context. However, it does not work when I use TLS_client_method().
if (!SSL_set_session(ssl, ssl_session)) { //code never reaches here so SSL_set_session is successful } if (SSL_connect(ssl) != 1) { return -1; } int reused = SSL_session_reused(ssl); <-- always returns zero for TLS_client_method(). ssl_session = SSL_get1_session(ssl); // for future connections Above code works fine with TLSv1_2_client_method() and SSL_session_reused() returns 1, handshake time is also reduced considerably. However, if I use TLS_client_method(), reuse does not work and SSL_session_reused() returns zero. Any idea what is wrong? OpenSSL version is 1.1.1.g
