What is an SSL certificate?

In simpler terms, an SSL certificate is what helps websites migrate from HTTP to HTTPS that is way more secure because they enable encryption and a host of other interesting benefits that will be discussed below.
Benefits of an SSL certificate
Having an SSL certificate is literally the only difference between a secure website and an unsafe website. SSL is paramount for guarding your website. It also provides a sense of privacy and data integrity for you and your client. Some other benefits include;
- Providing trust – A visual cues could give you a way to the client, for instance, a padlock shows the connection is secure. A trust seal will also come attached to the SSL certificate, which will be sure to give the client a great trust in your website.

How SSL certificate works
Just to repeat, SSL means secure socket layer. Here’s a simplified version of how these crucial elements of website security work:
- When a browser wants to connect with a website that’s encrypted with SSL, the browser sends a request to the website to identify itself.
- The website sends a copy of the certificate to the browser.
- The browser verifies the certificate.
- The browser sends replies with a digitally signed verification acknowledgement to commence the SSL encryption.
- Then encrypted data is shared among the browser and website.
So basically, when a browser initiates interaction with the server an SSL Handshake occurs. It’s asymmetric cryptography that enables the browser to verify the webserver (website), acquire a public key to encrypt information and set up a safe connection before any exchange of information.
