HTTPS

The secure version of HTTP that encrypts data transmitted between a browser and a web server using TLS.

Security

HTTPS (Hypertext Transfer Protocol Secure) is the encrypted version of HTTP, the protocol used for transferring data between web browsers and servers. HTTPS uses TLS (Transport Layer Security) encryption to protect the confidentiality and integrity of data in transit, preventing eavesdropping, tampering, and man-in-the-middle attacks.

HTTPS has become the standard for all websites, not just those handling sensitive data. Google uses HTTPS as a ranking signal, browsers display warnings for non-HTTPS sites, and many modern web features (like geolocation and service workers) require HTTPS. For URL shortening services, HTTPS is essential because users must trust that their clicks are secure and that the redirect process is not being intercepted.

Implementing HTTPS requires obtaining an SSL/TLS certificate from a Certificate Authority (CA). Services like Let's Encrypt provide free certificates, and cloud platforms like AWS and Cloudflare offer automated certificate management. The certificate must be renewed before expiration to avoid service disruptions.

For URL shortening services with custom domains, HTTPS configuration is a critical step. Each custom domain needs its own certificate, and the shortening service must handle TLS termination for all configured domains.
