The purpose of an SSL certificate on a website is to establish a secure connection between the user's browser and the web server. SSL, or Secure Sockets Layer, encrypts data transmitted, protecting sensitive information such as credit card details and personal data from potential breaches. Websites with SSL certificates display a padlock symbol in the address bar, indicating that the site is secure. This not only enhances user trust but also can positively impact SEO rankings. In today’s digital landscape, having an SSL certificate is essential for safeguarding online interactions.
