When we come to online, security comes first — either for you as a webmaster or visitors. For that SSL is the new security standard for protecting information by using advanced encryption.

In this article, we’ll learn what SSL is, what are it’s benefits and how to get an SSL certificate.
What is an SSL Certificate and How Does It Work?

How to install Free SSL?


Before we start the question “why do I need an SSL certificate” we should cover what it is. SSL stands for Secure Socket Layer — a protocol that is used to establish a secure connection.
It sets up a channel for data communication that applies encryption. Encryption is a practice for making information only readable to authorized users.
A website with an SSL certificate enabled will have always a URL that starts with https:// which is secure instead of http:// which is not secure. Depending on your browser, you’ll see a padlock icon at the left of web address in the address bar.


Having this padlock icon indicates that all processes on your website, from visitor input to server replies, will use a safe connection. That means it can prevent confidential data theft and misuse.
Breaching a connection secured with SSL is almost impossible because it applies both symmetric and asymmetric encryption. When applying asymmetric encryption, a public key is used to encrypt a message while a private key is used for decrypting it. On the other hand, asymmetric encryption uses only public keys for both procedures.
SSL certificates use those two cryptographic keys to validate data like the domain and server name, location, etc.

How does it work?

First off, a server will send a copy of its asymmetric public key. Once received, the
browser will generate a symmetric session key and encrypt it with the public key. After that, the server will decrypt the message using its private key. Having the same symmetric session key, the data transfer can take place.

Why is this secure?

As its name suggests, a session key is only valid for one session. That being said, for
another request, a new session key will be created.

Does My Website Really Need an SSL Certificate?

If your website is for private use, you may take the importance of an SSL certificate lightly. While, for a website expecting many visitors, it is critical.
Protecting visitor data is a must — especially when dealing with citizens of the European Union. Since GDPR took effect on May 25th, 2018, those who fail to protect customer data security will be penalized for up to €20 million.
If you run an online store and collect payment from your customers, you must safeguard the data transfer process. No customer will hand over their credit card information to an unsecured site. That means no transaction can take place.
This is why most ecommerce platforms like Big Commerce and Shopify are all SSL protected. All websites that collect visitor information must have SSL certificates enabled.
To sum up, if you run a website it’s a good practice to have an active SSL certificate as it is not expensive, but it will put your visitors at ease and make you look more trustworthy and professional.
