What exactly is an SSL certificate?

An SSL certificate is a digital certificate that authenticates the identity of a website and allows for an encrypted connection. SSL is an abbreviation for Secure Sockets Layer, a security protocol that establishes an encrypted connection between a web server and a web browser.

SSL certificates must be added to websites by businesses and organizations in order to safeguard online transactions and keep consumer information private and secure.

In a nutshell, SSL secures internet connections and prohibits hackers from accessing or changing data exchanged between two computers. SSL safeguards the website you are visiting if you see a padlock symbol next to the URL in the address bar.

How Does an SSL Certificate Function?

An SSL certificate is made up of two parts: the public key and the private key. When applying for an SSL certificate, you must first prepare a Certificate Signing Request (CSR) that includes corporate information for verification reasons. You will obtain your SSL certificate when the CA validates this information. Once you have your SSL certificate, the private key is equally crucial since it helps to encrypt and authenticate connections, but it is critical that you keep this key secret so that it cannot be exploited for identity theft.

The public key that is linked with your SSL certificate is just that: public. It enables people to verify SSL validity without access to your private key. Your web server is now safe, and all connections between devices are encrypted. This means that anybody intercepting connections between your server and browsers will be unable to view the information being transmitted, safeguarding any private data interactions.
