What is SSL
SSL is an encryption protocol used in the Internet. This protocol provides a secure connection between Internet browsers and websites, allowing Internet users to securely exchange their private data with other websites. The full form of SSL is Secure Sockets Layer.
SSL certificate is a digital certificate, whose full name is Secure Socket Layer. You can buy it for any website or any business. This creates a secure connection between your web browser and your web server. In this, the details of your business are enclosed in a cryptographic key.
This certificate contains your name, serial number, expiration date, your public key, and a digital signature provided by the authority that issued the certificate. Having an SSL certificate on a website means that you can trust this site, no hacker can see its information. This encryption technology was created by Netscape in 1990.
How does SSL work?
The SSL certificate encrypts all your information and sends it to the web server, and the web server does the same.
An SSL certificate consists of two combinations, a public key and a private key. The public key is used to encrypt the data being sent, while the private key is used to decrypt the data into a format that can be reused by the recipient of the data.
Suppose, you want to send money to a friend in a remote village, there is no mobile banking facility or internet. If you want to send money there, then for this you will have to hand over the money to someone. Now if you ask someone to reach his friend’s address with the money, he goes some distance and similarly transfers the money to someone else.
Here you can imagine how much your money is at risk. But if you lock the money in a box and send it, no matter who hands it over, there will be no fear of it being stolen – because the lock will open only with your friend’s key.
So this is what SSL certificate does. It securely transmits all the information you enter to the server. HTTPS is placed at the beginning of the URL of all websites using SSL. HTTPS is a hybrid version of SSL and HTTP. An HTTPS website means that the website has an SSL Certificate and is secure.
Types of SSL Certificate
There are many types of SSL Certificates, but in this article we will tell you about the 6 most important SSL Certificates, so let us know about the types of SSL Certificates.
1 – Single Domain SSL Certificate
This type of SSL certificate is installed on only one domain name, if you create any subdomain in future, then SSL is not installed on them.

3 – Wildcard SSL Certificate
Like Single Domain SSL Certificate, 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.
