HTTPS is a secure version of HTTP, the protocol used to transfer data between your web browser and the website you visit. Security is ensured by TLS, a cryptographic protocol that encrypts the exchanged data, making the information unreadable to unauthorized individuals. When you see “https://” in a website’s URL, it means that TLS is being used to protect the exchanged data, ensuring that your personal information, such as passwords or credit card numbers, remains private and secure from cyberattacks. In summary, HTTPS and TLS work together to secure your online communications and protect your sensitive data.
