An SSL (Secure Sockets Layer) checker is a tool used by SEO and webmasters to verify proper installation of SSL certificate on the web server hosting their website. We all know that connections on the internet between website visitors and web servers are not secure. To overcome this vulnerability, SSL was designed in the 1990s to secure HTTP connections between Netscape clients and web servers. SSL was eventually used to encrypt and authenticate communications over the internet at the transport layer of the network.

In 2015 the Internet Engineering Task Force replaced SSL with TLS (Transport Layer Security). Both these protocols are not interoperable TLS is backward compatible with SSL 3.0.

How SSL works

SSL uses a combination of keys, both public and a symmetric encrypted key to secure the connection between two machines (web server and client) over a public network. SSL runs on the network and the transport layer. Both these layers are responsible for transporting and routing data over a network. A point to note here is that when client setups a connection with a server it traverses over some networks and establishes a connection. SSL ensures that the connection established is secure and data can be transferred over it.

The SSL protocol has two sub protocols which are the 'handshake' and the record protocol. The handshake protocol establishes how data will be encrypted and authenticated for transfer between the two machines. The record protocol defines how data will be prepared and transmitted between the server and client.

Once the encryption code has been accepted on how data will be exchanged during that session between both the machines. The entire session of establishing the connection and authentication is invisible to the user. The client presents its certification, and the server verifies it before the session starts. If a user looks closely at the navigation bar on the search browser and sees a padlock icon, this indicates that the session is secure.

There were some issues with the SSL protocol, and that led to the evolvement of TLS. The term SSL or SSL/TLS are still commonly used to refer to the security protocol of the internet traffic. The SSL/TLS protocol is so widely used that Google reported that more than 50 percent of pages loaded on Google Chrome were using this protocol to establish and authenticate web server and client browsers.
