Imagine the internet without the little padlock in your browser’s address bar. No green “https://”, no guarantee that the data you enter — from your login to your credit card number — is safe from prying eyes. That’s what the world would look like without SSL certificates. And although today they seem invisible, these digital keys are what keep the modern web afloat.
SSL (Secure Sockets Layer) is an encryption technology that ensures secure data exchange between a user and a website. When you visit a page with HTTPS, your browser and the server “agree” on a unique key used to encrypt every byte of transmitted information. Without this mechanism, anyone positioned between you and the site could intercept your data — passwords, messages, files, or payment details. Today, dozens of organizations issue SSL certificates — from Let’s Encrypt to global certification authorities — all serving one purpose: to build trust between people and servers.
