TLS 1.2
TLS 1.2 (Transport Layer Security version 1.2) 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. It is widely used for securing web traffic (HTTPS), email, and other network services.
Developers should learn and use TLS 1.2 to implement 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 compliance with security standards (e.g., PCI DSS) and protecting against eavesdropping and man-in-the-middle attacks, though note that newer versions like TLS 1.3 offer improved security and performance.
