What is SSL certificates?

SSL stands for Secure Sockets Layer, 

It refers to a protocol for encrypting and securing communications that take place on the Internet.

SSL was replaced by an updated protocol called TLS (Transport Layer Security) 

The main use case for SSL/TLS is securing communications between a client and a server, but it can also secure email, VoIP, and other communications over unsecured networks.

TLS vs SSL

Both TLS and SSL are protocols. help in securely authenticate and transport data on the Internet. 

TLS, short for Transport Layer Security, and SSL, short for Secure Socket Layers, are both cryptographic protocols that encrypt data and authenticate a connection when moving data on the Internet.

The main difference between Secure Socket Layer and Transport Layer Security is that, in SSL (Secure Socket Layer), the Message digest is used to create a master secret and It provides the basic security services which are Authentication and confidentiality. while In TLS (Transport Layer Security), a Pseudo-random function is used to create a master secret. 

 TLS is actually just a more recent version of SSL. It fixes some security vulnerabilities in the earlier SSL protocols.

How Do TLS and SSL Work to Secure Data?

Here’s the high-level process for how both SSL and TLS work.

When you install an SSL/TLS certificate on your web server (often just called an “SSL certificate), it includes a public key and a private key that authenticate your server and let your server encrypt and decrypt data.

When a visitor goes to your site, their web browser will look for your site’s SSL/TLS certificate. Then, the browser will perform a “handshake” to check the validity of your certificate and authenticate your server. If the SSL certificate is not valid, your users may be faced with the “your connection is not private” error, which could cause them to leave your website.

Once a visitor’s browser determines that your certificate is valid and authenticates your server, it essentially creates an encrypted link between it and your server to securely transport data.

This is also where HTTPS comes in (HTTPS stands for “HTTP over SSL/TLS”).

HTTP, and the more recent HTTP/2, are application protocols that play an essential role in transferring information over the Internet.

With plain HTTP, that information is vulnerable to attacks. But when you use HTTP over SSL or TLS (HTTPS), you encrypt and authenticate that data during transport, which makes it secure.

This is why you can safely process credit card details over HTTPS but not over HTTP, and also why Google Chrome is pushing so hard for HTTPS adoption..
