TLS
TLS (Transport Layer Security) is a cryptographic protocol that provides secure communication over a computer network, such as the internet. It ensures privacy and data integrity between two communicating applications by encrypting data, authenticating parties, and preventing tampering. TLS is the successor to SSL (Secure Sockets Layer) and is widely used in web browsing, email, instant messaging, and other applications.
Developers should learn and use TLS to secure data transmission in applications, especially for web services, APIs, and client-server communications where sensitive information like passwords or financial data is exchanged. It is essential for implementing HTTPS in web development, protecting against eavesdropping and man-in-the-middle attacks, and is required for compliance with security standards like PCI DSS.
