What is an SSL certificate?

An SSL certificate is a digital certificate that confirms a website’s identity and enables a secure connection. SSL (Secure Sockets Layer) is a security technology that creates an encrypted link between a web server and a web browser.

A certificate authority (CA) is a reputable institution that confirms a website’s legitimacy. The CA evaluates the certificate requester’s information to industry standards, such as site ownership, name, and location, before issuing a certificate. The CA also uses their own private key to digitally sign the certificate, allowing clients to validate it.

Details typically included within SSL certificates include:

  • The certificate was obtained for this website.
  • The following organization received it.
  • The name of the issuing CA.
  • The CA’s digital signature.
  • Subdomains with a connection.
  • Certificate issuance and expiration dates.
  • The password.

How does an SSL certificate work?

SSL makes it harder to read data sent between people and websites, or between two systems. It encrypts data in transit to prevent hackers from gaining access to it while it travels across the network. Potentially sensitive data includes names, addresses, credit card numbers, and other financial information.

The procedure is as follows:

  1. A browser tries to connect to an SSL-secured website.
  2. The web server is asked to identify itself by the browser or server.
  3. In response, the webserver delivers a copy of its SSL certificate to the browser or server.
  4. The certificate is checked by the browser or server to see if it is trusted. If it does, the webserver will be notified.
  5. After that, the webserver sends a digitally signed acknowledgment, which initiates an SSL secured session.
  6. The web server and the browser or server exchange encrypted data.

Only the characters HTTP – not the S for Secure – will appear without an SSL certificate. In the URL address bar, a padlock icon will also appear. Visitors to the website will feel more secure because of this.
