Usually, when we browse an HTTPS website, one-way SSL is being used where only our browser (client) validates the identity of the website (server). Two-way SSL is mostly used in server to server communication where both parties need to validate the identity of each other.
How does SSL handshake protocol work?
SSL Handshake
- The client sends a “client hello” message.
- The server responds with a “server hello” message.
- The client verifies the server’s SSL certificate from CA (Certificate Authority) and authenticates the server.
- The client creates a session key, encrypts it with the server’s public key and sends it to the server.
Who initiates the SSL handshake?
An HTTPS connection involves two parties: the client (the one who is initiating the connection, usually your web browser), and the server. These two parties are the ones that ‘shake hands. ‘ The purpose of the SSL/TLS handshake is to perform all the cryptographic work needed to have a secure connection.
What do you need to know about the SSL handshake?
What Is an SSL/TLS Handshake? An SSL/TLS handshake is a negotiation between two parties on a network – such as a browser and web server – to establish the details of their connection. It determines what version of SSL/TLS will be used in the session, which cipher suite will encrypt communication, verifies the server
What do you need to know about two way SSL?
Two-way SSL is mostly used in server to server communication where both parties need to validate the identity of each other. During an SSL handshake, the server and the client follow the below set of steps. 1. Client Hello The client will send the information that will be required by the server to start an HTTPS connection.
Is there a shortcut to the TLS handshake?
(Remember that asymmetric encryption is costly time- and resource-wise – using the cipher suite as a shortcut speeds up the handshake itself.) TLS specifications allow for quite a number of cipher suites, and the client and server will almost always have access to one they can both employ.
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.
