How does SSL work between client and server?
SSL works by authenticating clients and servers using digital certificates and by encrypting/decrypting communication using unique keys that are associated with authenticated clients and servers. An entity’s identity is established using a digital certificate and public and private encryption keys.
What is server handshake?
The reason it’s called a handshake is that it’s when two parties – client and server come across each other for the first time. The handshake involves a number of steps that start from validating the identity of the other party and concludes with the generation of a common key – secret key if you may call it.
What is client random TLS?
The SSL or TLS client sends the random byte string that enables both the client and the server to compute the secret key to be used for encrypting subsequent message data. The random byte string itself is encrypted with the server’s public key.
What happens in a client hello SSL handshake?
Client hello: The client sends a client hello message with the protocol version, the client random, and a list of cipher suites. Server hello: The server replies with its SSL certificate, its selected cipher suite, and the server random.
What happens at the end of a certificate handshake?
In such scenarios, the client may choose whether to send or avoid sending of the client certificate (depends on the client implementation) Finally, the server sends the Server Hello Done message indicating the end of Server Hello. After sending this message, the server will wait for a client response.
What is a TLS handshake and what does it mean?
TLS handshakes are a series of datagrams, or messages, exchanged by a client and a server. A TLS handshake involves multiple steps, as the client and server exchange the information necessary for completing the handshake and making further conversation possible.
When does the server send the Hello done message?
In such scenarios, the client may choose whether to send or avoid sending of the client certificate (depends on the client implementation) Finally, the server sends the Server Hello Done message
