SSL is an acronym derived from the term ‘Secure Socket Layer’. In the context of websites, it refers to a type of certificate and security protocol that plays a vital role in encryption.

This is particularly important in today’s world because we now carry out almost everything via the internet, and users must be assured that their personal data is protected, whether it be passwords or bank account numbers.

SSL helps to protect such sensitive information by providing an encrypted connection between our website, the server hosting it and the visitor, so users can be confident that their data is secure.

How does SSL work?

The way an SSL certificate works is extremely simple. When a user visits a website with this kind of setup, the SSL creates a separate channel and a unique session ID for that connection.

These two keys must always match. Once this is confirmed, the browser checks the validity of the SSL certificate on the server; if it finds it to be valid, it authorises the connection and confirms this to the server, which in turn approves the request.

This process is known as the SSL handshake, which is essential for establishing an encrypted and secure connection.

How can a website obtain an SSL certificate?

Virtually every website has the option to request and use an SSL certificate, though this does not, of course, mean that every single one will actually be granted the standard that indicates a secure and encrypted connection.

Whether you’re a prospective or existing website owner, you can always apply for an SSL certificate through your hosting provider. In many cases, all you need to do is configure it in cPanel, and then, once you’ve paid any applicable fees, you can enjoy the benefits it offers.

Most web hosting providers, of course, provide SSL certificates to their users free of charge, so website owners simply need to configure them to ensure they are up and running.

It is important to note, however, that SSL certificates are generally only valid for one or two years, so they are not indefinite. You could say they require ongoing renewal, which can be carried out in exactly the same way as when you originally applied for them.

How can you tell if a website has an SSL certificate?

Nowadays, most websites operate with an SSL certificate, i.e. with encryption. In certain cases, this is an essential requirement, particularly for an online shop or an online bank, as an encrypted connection is indispensable in such instances to protect user data.

It’s easy to spot – you just need to look at the website’s address bar. If you see that the domain name begins with https:// rather than http://, you can be sure you’re on a secure connection.

These days, SSL certificates are important from an SEO perspective too!

Last but not least, when it comes to SSL certificates, it is very important to know that their use is also extremely important from an SEO perspective. For several years now, Google has been giving higher rankings in its search results to websites that use this method of encryption.

If you’re thinking of launching an online shop, SSL will be absolutely essential, as it’s the only way to offer credit card payments, whilst also significantly boosting the trust that more discerning users place in your business or brand.
