TLS

TLS (Transport Layer Security) is a cryptographic protocol that provides secure communication over a computer network, such as the internet. It ensures privacy, data integrity, and authentication between two communicating applications, commonly used to secure web traffic (HTTPS), email, and other data transfers.

Also known as: Transport Layer Security, SSL, HTTPS, Secure Sockets Layer, TLS/SSL

Why learn TLS?

Developers should learn and implement TLS to protect sensitive data from eavesdropping, tampering, and forgery in applications handling user information, financial transactions, or confidential communications. It is mandatory for compliance with security standards like PCI DSS, GDPR, and for building trust with users in web and mobile apps.
