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. SSL (Secure Sockets Layer) is its predecessor, now deprecated in favor of TLS due to security vulnerabilities.
Developers should learn and use TLS to protect sensitive data in transit, such as passwords, payment information, and personal details, in web applications, APIs, and network services. It is essential for compliance with security standards (e.g., GDPR, PCI DSS) and to prevent man-in-the-middle attacks, eavesdropping, and data tampering. Use cases include implementing HTTPS on websites, securing mobile app communications, and encrypting database connections.
