SSL certificate
An SSL certificate is a file installed on a website's origin server. It is a data file containing the public key and the identity of the website owner, along with other information. Without an SSL certificate, a website's traffic can't be encrypted with TLS.
The SSL Certificate is necessary for the website’s security. When your site sells products and services and sees monetary transactions via credit cards online, a certificate is mostly important.
