What Does Secure Sockets Layer Certificate Mean?

A Secure Sockets Layer (SSL) certificate is a form of Web authentication used to validate website security and provide identity protection to website users. SSL certificates are issued by a certification authority (CA).

Techopedia Explains Secure Sockets Layer Certificate

Web security is essential for website safety. An SSL certificate ensures identity protection and tightens network security. Many e-commerce websites purchase SSL certificates to bolster customer and visitor trust.

During the SSL process, visitor data is encrypted. For example, a user visits a website. The website and user servers then exchange a handshake and determine an encryption format. Data is encrypted and unencrypted upon receipt by either server.

There are three types of SSL certificates:

  • Extended Validation (EV) SSL Certificate
  • Organization Validation (OV) SSL Certificate
  • Domain Validation (DV) SSL Certificate
