Let’s Dive Deeply to Know All About SSL Certificate

Understanding SSL certificates is crucial in a world where digital transactions and communications rule the day in order to protect sensitive data and ensure secure connections. Consider it as a digital introduction between your device and the server of a website, creating a safe path for data transmission that is impervious to interception. So, what basically is an SSL Certificate? 

It is a digital certificate known as an SSL (Secure Sockets Layer) certificate allows safe, encrypted communication between a web server and a web browser and validates the authenticity of a website. Though SSL is the more widely used word, all SSLs these days are based on TLS protocol. TLS (Transport Layer Security) is a more secure successor to SSL.

These protocols encrypt sensitive data being transported across the network using intricate algorithms. In this manner, every communication between a client and server is kept confidential and safe from online fraud.

How Does SSL Certificate Work? 

Your web browser establishes a connection with the website's server when you visit a website over HTTPS. After that, your browser (SSL Client) asks the server for verification in order to validate the legitimacy of that website. The browser receives a bit of encoded text from the SSL server along with its SSL certificate and public key. Here are some steps mentioned in more detail for your easy and better understanding of how does SSL certificate works:

SSL Certificate Work
  • A user's web browser initiates a request to the website's server to create a connection when they try to access a website that is secured using SSL.
  • After that, the server answers the request by presenting its SSL certificate to the browser.
  • The SSL certificate's authenticity is then confirmed by the web browser.
  • A cryptographic handshake process is started between the browser and server after certificate verification. 
  • Data sent between the browser and server is encrypted once a secure connection has been made.
  • Secure internet transmission of encrypted data keeps it safe from interception by unauthorized parties.

Why Does Your Website Need an SSL Certificate?

Any website must have an SSL certificate that is both valid and configured correctly, supplied by a reliable certificate authority. Additionally, your website needs an SSL (Secure Sockets Layer) certificate for a number of reasons that enhance security, credibility, and user experience. Some of these reasons, we have mentioned below:

Website Need an SSL Certificate


Data Encryption:
Data sent between a user's web browser and your website's server is encrypted thanks to an SSL certificate. Sensitive data, including login passwords, credit card information, and personal information, is protected from hostile actors or cyber criminals.

Trust & Credibility: A padlock icon and "https://" in the browser's address bar denote a secure connection on websites that have SSL certificates. Visitors are given comfort and reassurance that their interactions with your website are safe and secure by this visual signal. 

Security: SSL certificates assist in defending your website and its users against a range of online dangers, such as identity theft, data breaches, and man-in-the-middle attacks. SSL certificates reduce the possibility of unwanted access to private data by encrypting it while it is in transit, protecting both your users and your brand.

Improved User Experience: SSL certificates help your audience become more dependable and devoted, which eventually improves user retention and happiness. Users are more inclined to connect with your material, make purchases, and visit you again if they have faith that their interactions with your website are safe. 

SEO Advantages: Google declared that its search algorithms would take SSL/TLS encryption into account when assigning rankings. Increased exposure and organic traffic might occur from websites with SSL certificates since they are more likely to rank higher in search engine results pages (SERPs). 

Understanding What is SSL Certificate Error & It’s Types

An SSL certificate error may be caused by an issue with the website's certificate itself or with the way it is set up on the server. If your browser encounters any problems establishing a secure connection with a website, it will show a specific error message. You might have heard about the WordPress security problems, but this SSL certificate error is another important thing, you must be known about.

A Comprehensive Guide on “How to Solve SSL Certificate Error Message”

In the current digital era, SSL certificate issues can be annoying because online security is crucial. When trying to access websites, these error messages frequently show as warnings, highlighting possible security dangers and making it more difficult for you to establish a secure connection. Now, without wasting any further minutes, let’s start knowing how we can resolve this issue, as this guide contains all the easy steps regarding “how to solve SSL certificate error message”

1. Make Sure Your Website Has an SSL Certificate Installed

First things first, make sure that your website has an SSL certificate installed. You can make sure of it by simply checking the URL of your website in your browser. When any website has an SSL certificate its URL always starts with HTTPS instead of HTTP. You may also get to see a padlock icon in the bar which will indicate that the connection is secure. 

2. Detect the Problem with an Online Tool

Now, if your website has an SSL certificate and your browser is still showing an error, you can always use an online tool to detect the problem, causing that SSL certificate issue. You go for any of the tools listed below

  • SSL Checker 
  • SSL Certificate Checker
  • SSL Server Test

With the help of these tools, you can easily come to know if your SSL certificate is expired or not, if the domain name in the certificate matches the name in the URL, and many more. So, it will be easy to solve this error message.  

3. Install an Intermediate Certificate on Your Web Server

If your browser is unable to trace the SSL certificate back to the root certificate or the problem is that your certificate authority is not trusted, then you might need to install an intermediate certificate on your web server. This will help your browser establish that your website’s certificate is issued by a valid root. 

4. Generate a New CSR - Certificate Signing Request

However, if your browser is still showing the error, then you might have not installed the certificate properly. In this scenario, you can simply generate a new CSR (certificate signing request) and reissue it from your certificate provider. And, that way you can easily resolve the SSL certificate error message. 

5. Upgrade to a New Dedicated IP Address

If you are facing any name mismatch SSL certificate issue, then it is probably because your IP address is having a problem. In this case, the browser is unable to define which domain the SSL is signed for.  Especially if you are on a shared hosting, then your site must be sharing the same IP address with other websites, as well. Therefore, the browser cannot identify if the SSL matches your domain name in the URL. 

6. Try Getting a New Wildcard SSL Certificate

Another way to resolve that mismatch name SSL certificate error is to get a new wildcard SSL certificate. This card will not only cover your root domain but will also cover the subdomains. For example, if you have one main domain and want to secure its subdomains, as well, getting a new wildcard is a perfect solution. 

7. Change All the URLs to HTTP

Change of all the URLs to HTTP is needed when you get a mixed content error on your screen while loading the website. Here, you need to identify the insecure elements that are causing this error. Once you are successful in identifying the elements, you can change the source code and can change the URLs of those insecure elements to the HTTP.

8. Do Not Forget to Upgrade Your SSL Certificate

You will get an expired SSL certificate error when the lifespan of the certificate comes to an end. In this case, you need to upgrade your SSL certificate to run your site smoothly and securely. The details of upgrading depend on the web host or the certificate authority you are using. 

Bringing It All Together!

After knowing all the details regarding the SSL certificate, its error, and how to resolve this error, you might find it easy to identify the error and then its solution. With this comprehensive guide, you can easily detect what type of SSL certificate your browser is showing and how you can fix it quickly because these errors can be annoying and can waste a lot of time if the owner of the website is not familiar with these problems. Thus, before integrating an SSL certificate for the security of your website, you need to know everything about it that we have mentioned.
