What is an SSL Certificate? (What is SSL)

SSL Certificate is a digital certificate that provides authentication for a website. SSL stands for Secure Sockets Layers, which is a standard technology protocol that enables encrypted connections between web servers and web browsers. Which protects the private data shared by users.

In other words, an SSL Certificate is used to ensure Internet Security by preventing any third party with malicious intent from transmitting, reading, or modifying any information.

An ideal use case for using an SSL Certificate is an online store. Typically, they have a lot of transactions that contain personally identifiable information and credit card information. Without an SSL certificate, this sensitive data will be exposed to a third party.

When you open a website in your browser, in the search bar you see http or https written before the domain name of the website. Any website that has https written in its beginning. It is completely safe and secure. All the information shared by you on such websites remains completely secure.

When this type of website is entered in the search bar. Then if you click on the icon in front of it, in the 1st you will see Connection is Secure written. Which means that the website you searched is completely safe. Whatever data you share will be completely secure.

With SSL: https://example.com

Without SSL: http://example.com

SSL is also called Transport Layer Security i.e. TLS Protocol. Which is used in many places like websites, e-mail, etc. If someone has an e-commerce site, then it is very important to use SSL, because after purchasing the product from his site, users have to provide all the details of their bank account to make payment.

Examples of SSL Certificate

You can see my website to understand the example of an SSL Certificate. When you see the URL of my website in the search bar, you will see https written before the domain name. Apart from this, if you click on the icon in front of this URL, you will find Connection is Secure written. This means that my website is completely safe, you can share anything like your Email ID, Bank Details, etc. on it, and it will be completely safe.

But if you see HTTP written instead of https before the URL of any website in the search bar, then you should be careful and never share your private information with such websites because these types of websites are not safe. Such websites can misuse your data.

Types of SSL Certificates

#3 – Wildcard SSL Certificate

Like a Single Domain SSL Certificate, a Wildcard SSL Certificate is installed on only one domain name. However, this type of SSL certificate is also installed on subdomains of that domain name. For example, a Wildcard SSL Certificate can cover www.a2zhindime.com, story.a2zhindime.com, and technology.a2zhindime.com, while a Single Domain SSL Certificate can only cover the domain name.

It requires a complete background check of an organization before issuing an SSL Certificate. With the use of this type of SSL Certificate, the search bar in which the URL of the website opens is green in color and the name of the business is also shown. This is a high-security SSL certificate.
