SSL certificate
An SSL certificate is a small file that tells your browser and your website how to securely talk to each other.
An SSL certificate is a digital file that helps protect the information people send to and from your website. It works by creating an encrypted connection, which means your visitors' data—like credit card numbers or login details—is scrambled so it can't be read by anyone who might intercept it.
What it means
When a website has an SSL certificate, it uses a protocol called HTTPS instead of HTTP. This shows your visitors that the connection is secure. You'll often see a padlock icon in the browser address bar when a site is using SSL.
Why it matters
Without SSL, sensitive information can be stolen by hackers. Even if your website isn't handling financial data, having an SSL certificate helps build trust with your visitors and can improve your search engine rankings.
What to do
If you run a website, you should get an SSL certificate from a trusted provider. Many hosting companies offer free certificates through services like Let's Encrypt. Once you install it, make sure your site uses HTTPS everywhere, including images, scripts, and forms.
