Every SSL/TLS connection begins with a “handshake” – the negotiation between two parties that nails down the details of how they’ll proceed. The handshake determines what cipher suite will be used to encrypt their communications, verifies the server, and establishes that a secure connection is in place before beginning the actual Jan 31, 2020 · TLS negotiation errors occur when clients try to connect to a load balancer using a protocol or cipher that the load balancer's security policy doesn't support. To establish a TLS connection, be sure that your client supports: One or more matching ciphers; A protocol specified in the security policy Transport Layer Security (TLS), and its now-deprecated predecessor, Secure Sockets Layer (SSL), are cryptographic protocols designed to provide communications security over a computer network. Several versions of the protocols find widespread use in applications such as web browsing , email , instant messaging , and voice over IP (VoIP). A TLS handshake is the process that kicks off a communication session that uses TLS encryption. During a TLS handshake, the two communicating sides exchange messages to acknowledge each other, verify each other, establish the encryption algorithms they will use, and agree on session keys.
