What Is SSL? (& SSL Certificate Types)

If you are making a website, you have to know all the security features that you should have when doing it. SSL is a security feature, and you need to have one on your website, especially if you are holding any information related to your site members, or vital information such as banking data. SSL stands for Secure Sockets Layer. It is a security technology that creates an encrypted link between a server and a client. A server here means a website, and the client can be a browser, a mail server, or a mail client such as Outlook. 

How Does SSL Work

How Does SSL Work?

SSL carries high importance because it provides secure transmission of sensitive information such as credit card numbers, social security numbers, and login credentials. If a website has a membership option, it means that the website carries the information of its members. So it is important that checking if the website has an SSL when signing in for a website. Yet, how can you know if a website has SSL? It is pretty easy to see. When you take a look at the address bar, you will see that it writes ‘https.’ This means that the website has SSL. If you only see ‘http,’ it means that the website does not have one. 

What happens if the website does not have SSL? The data is sent between browsers and servers in plain text. It means that the information is clearly visible. So, without a Security Sockets Layer, a malicious hacker can see the information being sent between the server and the client, get it and use it for malicious purposes.

Of course, SSL is not just a security software that protects your data on your website. It is also a security protocol. A protocol describes how the algorithms in their area should be applied. In this case, the SSL security protocol determines the encryption of both the connection and the data being transmitted. 

Why Is SSL Important?

As we have stated before, it is important because it secures the transmission of sensitive information. Every day, millions of people make online transactions without a problem, thanks to SSL. We have mentioned that it is important for banks. For example, when making a money transaction, you enter valuable information such as your credit card number, account number, etc. The same thing can be said for online shopping as well. You may not be aware of it, but if it wasn’t an SSL security protocol, your information could have ended in the wrong hands. 

All browsers are suitable to work with an SSL. However, not all servers (websites) have it. If you want your website to secure the information inside, you have to get an SSL certificate to do it.
