Are you wondering what an SSL certificate is and why you need one, well, In this article, you will learn what is an SSL certificate and how it works.

SSL certificates are security essential to the World Wide Web. They benefit both website owners and internet surfers.

Consumers can feel safe shopping online or accessing private information without the worry of having their credentials stolen by hackers over a wireless network.

Website owners enjoy added protection from hackers as well as a boost in credibility with consumers.

An SSL certificate is a form of digital identification that allows secure connections between websites and browsers,

encrypting communications sent across networks such as WiFi hotspots or cellular data networks.

The SSL technology is now recommended worldwide by all major web browsers,

including Google Chrome, Microsoft Internet Explorer, Mozilla Firefox, Apple Safari, Opera browser and others.

It was previously known as Secure Sockets Layer but has now evolved into Transport Layer Security or TSL.

SSL technology is a means of security for data sent from a browser to a web server.

It establishes an encrypted link between them,

which in turn ensures that all data sent remains private and under the sole control of the website owner controlling the webserver.

It also verifies that website owners are who they claim to be.

SSL certificates also add an extra layer of security that prevents e-commerce fraud such as credit card theft or identity theft.

The encrypted link makes it extremely difficult for hackers to intercept data being sent between the web server and browser because,

without the SSL technology, all data is sent in plain text using a numerical code system which can very easily be intercepted by electronic eavesdroppers.

Without SSL certificates, any online business transactions are impossible to ensure true privacy during transmission.

SSL certificates give website owners an opportunity to improve consumer confidence and increase business.

With SSL certificates it is easier to gain trust, which means more sales and greater revenue.

What is an SSL Certificate?

explanation of an ssl certificate

An SSL certificate is a file hosted in the origin of a web server that attaches a cryptographic key to a website/organization’s details.

The main purpose of the SSL certificate is to provide a secure connection between a web server and a user’s browser.

What is SSL?

SSL (Secure Sockets Layer) is a security technology that enables encrypted communication between a browser and a server.

It is used to decrease the risk of losing sensitive information (like usernames, passwords, credit/debit card numbers, etc.) to hackers.

How many times have you been on the internet and clicked “I agree” to the terms of the use of a website?

Well, you are making it extremely easy for hackers to get into your computer. How do they do that?

What is ssl

When you know what an SSL certificate is then you will be able to understand how important it is to keep your computer secure from hackers.

An SSL stands for Secure Sockets Layer. It offers end-to-end encryption through HTTPS protocol.

To put it simply, when you type in a URL, for example, the letters at the beginning of that (https) is an SSL certificate.

When someone wants to record any personal data such as passwords and credit card information – this is where an SSL certificate is used.

When you are sending your data to a particular website, for example, there is a chance that this could be intercepted by someone who can see all the traffic going over the public network – the internet.

With SSL certificates, there will be an encrypted connection between your web browser and the server hosting the website.

This process involves a third-party digital certificate authority so the two parties can trust each other to share data securely, whether it’s your personal info or even credit card details.

So there you have it.

The use of SSL certificates is vital for any business, especially if they are involved in the financial industry, to protect their customer’s personal information.

The use of SSL certificates can also make users feel safe and secure with the data they are sharing online; without them, any piece of information sent out is not private or confidential at all.

A hacker could easily intercept the user’s information if there was no use of an SSL certificate that encodes the information before it is sent out.

How does the SSL certificate work?

What it does typically is that it activates both padlock and HTTPS protocol thereby causing secured connections from a web server to a user’s browser.

Millions of sensitive information are transmitted by internet users on a daily basis ranging from bank statements to security numbers.

To avoid the interception and manipulation of this data by third parties, the SSL certificate was adopted.

It encrypts the data transmitted by internet users from a web server and decrypts it as soon as it gets to its destination.

They create a secured connection from a web server to a user’s browser.

How to migrate or switch from HTTP to HTTPS?

Have you been sorting for ways to move your WordPress site from HTTP to HTTPS?

This article should guide you on how to change the URL from HTTP to HTTPS on the WordPress website.

Before we dive deep, I will like to give a clear definition of some terms.

http to https migration

What is HTTP?

HTTP is an acronym that stands for Hypertext Transfer Protocol. It is the fundamental protocol used in the transfer of files online.

It grants internet users the privilege of interacting with web resources by transmitting hypertext messages between clients and users.

Basically, HTTP makes use of the TCP protocol to communicate with servers.

HTTP is not secured because the connection it provides is not encrypted.

Hence, the not secure warning response you receive, anytime you navigate to a site without HTTPS.

What is HTTPS?

HTTPS is the secured version of HTTP, it is an acronym that stands for Hypertext Transfer Protocol Secure.

It makes use of an SSL certificate to ensure the secured connection between a user’s browser and a server via an encryption method making it difficult for third parties to invade.

Once the data is encrypted, it is transmitted into numbers and letters that can’t be accessed by humans due to their complexity.

For instance, you visit a website to buy some product and you provided them with your bank information and some other personal information,

the job of HTTPS is to provide a secure connection that protects your data transfer and personal information from third parties.

Why you should move from HTTP to HTTPS?

1. It was mandated by Google.

In 2018, Google released an update that covers the intention of improving web security.

Similarly, all website owners were encouraged to move from HTTP to HTTPS.

2. Google also stated that sites that switched from HTTP to HTTPS will enjoy SEO benefits and higher rankings.

3. If you are still stuck with HTTP then chrome and other web browsers will notify users that “this site isn’t secure to navigate”.

Both HTTP and HTTPS are protocols that are essential criteria to run a website on a secured platform.

The protocol is, however, defined as certain rules and regulations we should follow to make the website and the whole system out of danger.

4. Change links containing HTTP to HTTPS in your content and database.

The next step in moving your site from HTTP to HTTPS is to update the links in your content that contain the HTTP protocol.

For easy updates, you can make use of the Velvet blues update URL plugin.

Links that will be altered include:

  1. Media (Images, audio files, PDF, videos)
  2. Internal links
  3. CSS and Javascript files
  4. Web fonts

5. Add the 301 redirects in your .htaccess file

The next step you should take in moving your sites to HTTPS is implementing a redirect that leads visitors to the secured version of your site automatically.

To enable this, we will make use of the .htaccess file that is located in the WordPress root directory of your site.

The file contains settings for permalinks, so it’s very possible you have one already.

To locate it, allow your FTP clients to show hidden files because by default the .htaccess is invisible.

If you don’t have one, simply create a plain text file and name it as .htaccess, then upload it to the WordPress root directory of your site.

.htaccess http to https redirect code

Copy the above code.

With the redirect in place, rest assured that your visitors will be directed to the HTTPS version of your site.

Cross-check to be sure that none of your content is available in HTTP and HTTPS versions.

Duplicate content poses a threat to your site’s SEO.

After the above steps have been implemented, it’s now time to check that your site functions correctly.

To do this, kindly use the SSL test to do a total check-up of your site.
