An SSL certificate is a digital document that authenticates the identity of a website and encrypts the information that is sent to and from the site. SSL certificates are used to protect sensitive information, such as credit card numbers and passwords, from being intercepted by third parties.
SSL certificates are essential for any website that collects or transmits sensitive information. They help to protect users from phishing attacks and other online threats. In addition, SSL certificates can improve a website’s search engine ranking and make it more trustworthy to users.
