These processes are performed in the handshake protocol. In SSL session tickets, the client and server negotiate whether they support SSL session tickets during the handshake exchange. If the user's browser is configured to query certificate revocation lists and the CRL server is not reachable, the initial SSL handshake may take a significant time until the browser gives up waiting for the CRL. In SSL/TLS, the two communicating parties (the client and the server) generate 4 session keys at the start of any communication session, during the TLS handshake. From the OpenSSL documentation: 'SSLv23' uses a handshake compatible with SSL2. During a two-way handshake, both the client and server must present and accept each other's public certificates before a successful connection can be established. int mbedtls_ssl_ticket_parse_t(void *p_ticket, mbedtls_ssl_session *session, unsigned char *buf, size_t len). 2) or on a cipher suite. ssl_sni -m end -i sub2.

One megabyte of the cache contains about 4000 sessions. I still get the "Error: cURL ERROR: 28: SSL connection timeout. A public key and the digital signature of the SSL certificate issuer will be used to verify authenticity. In a typical SSL usage scenario, a server is configured with a certificate containing a public key as well as a matching private key. Here are the four steps involved in a TLS handshake: Indicating the TLS version which will be used for communication. EXAMPLE: If VoIP connections timeout after 60 seconds we would adjust the firewall rule for VoIP traffic and change the UDP timeout value to 60 seconds. When this is complete, the master secret, cipher suite, and certificates are stored in the session cache on the respective client and server. Alternatively PKCS12 files are also supported. Implementing SSL/TLS can significantly impact server performance, because the SSL handshake operation (a series of messages the client and server exchange to verify that the connection is trusted) is quite CPU-intensive. 0) or RFC 5246 (TLS 1.
