The web server sends a public key along with its SSL certificate. Your browser requests secure pages (HTTPS) from Norton’s web server. You type in a secure website’s URL, indicated by an HTTPS address: “”. When your browser tries to connect to a secure website, several steps take place in only a few milliseconds: The encrypted data is impossible to read without a secret key, called a decryption key. SSL certificates work by establishing an encrypted connection between a web browser and a server. Without a secure connection, the above data can become susceptible to man-in-the-middle attacks, among other cyberattacks. Since researchers predict e-commerce will make up 17 percent of all U.S. retail sales by 2022, there is a growing need for both web users and webmasters to keep sites secure.īy ensuring that all data passed between the two parties remains private and secure, SSL encryption can help prevent hackers from stealing private information such as: It is commonly used on e-commerce sites and pages that require users to submit personal or credit card information.

Today’s digital citizens face many emerging threats, and making sure the websites you visit are secure is one important way you can protect your information. Secure websites help web users protect their sensitive information, like credit card or Social Security numbers. This authentication process is much like sealing a letter in an envelope before sending it through the mail. 
In order to receive an SSL certificate, the web service host must demonstrate ownership of the domain to the certificate authority at the time of certificate issuance.
Additionally, sites will display an “HTTPS” address instead of an “HTTP” address. When a website holds an SSL certificate, a padlock icon appears on the left side of the URL address bar signifying that the connection is secure. Short for Secure Sockets Layer, SSLs communicate to web users that a connection is safe and secure. An SSL certificate is a type of digital certificate that provides authentication for a website and enables an encrypted connection.
