HTTPS/TLS
HTTPS (Hypertext Transfer Protocol Secure) is a secure version of HTTP that uses TLS (Transport Layer Security) to encrypt data transmitted between a client (e.g., web browser) and a server, ensuring confidentiality, integrity, and authentication. TLS is a cryptographic protocol that provides secure communication over a network by establishing an encrypted connection, preventing eavesdropping, tampering, and forgery. Together, HTTPS/TLS are fundamental for protecting sensitive information like passwords, payment details, and personal data on the web.
Developers should learn and use HTTPS/TLS whenever building web applications that handle user data, require secure authentication, or must comply with privacy regulations like GDPR or PCI DSS. It is essential for e-commerce sites, banking platforms, APIs transmitting sensitive data, and any service where security is a priority to prevent man-in-the-middle attacks and data breaches. Implementing HTTPS/TLS also improves SEO rankings and user trust, as modern browsers flag non-secure sites.
