SSL (Secure Sockets Layer) and TLS (Transport Layer Security) are two different protocols used by web browsers and web servers to communicate securely. They are both used to protect data during transmission, ensuring that information sent between the browser and server is secure and cannot be intercepted by a third-party.
SSL is the older of the two protocols, having first been introduced in 1994. It works by using a secure connection to encrypt data. This is done by establishing a “handshake” between the browser and the server, which involves the server sending a “public key” to the browser. The browser then verifies the key with the server and creates a session key, which is used to encrypt any data sent between the two. This process is known as “SSL handshake” and is performed every time a secure connection is established between the two.
TLS is the newer of the two protocols, having been introduced in 1999. It works in a similar fashion to SSL, but is more secure because it uses a stronger encryption method and is more resistant to attacks. TLS also includes additional features, such as session resumption, which allows the server to resume a secure connection without having to go through the entire SSL handshake process again. Both protocols are important for keeping data safe when browsing the web.
Websites that use SSL or TLS are often identified by a padlock icon in the browser, which indicates that a secure connection is being used. It is important to make sure that any website you visit is using a secure connection, as this will help protect your data from being accessed by malicious actors.
SSL and TLS are both essential protocols that are used to keep data safe when browsing the web. Although TLS is more secure than SSL, both protocols are necessary for ensuring a secure connection between a browser and server. By making sure that websites you visit are using a secure connection, you can help protect your data from potential threats.
