An SSL certificate is a digital certificate that authenticates a website’s identity and enables an encrypted connection between a web server and a browser. This encryption ensures that any data transferred between the user and the website, such as personal information or payment details, is kept secure from unauthorized access. SSL certificates are critical for building trust with users, as they provide visual cues like the padlock icon in the address bar, signaling that the connection is secure. Websites with SSL certificates also benefit from improved SEO rankings, as search engines prioritize secure sites. For these reasons, securing a website by implementing an SSL certificate is essential for protecting sensitive data and enhancing the credibility of a website in the eyes of visitors.
