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 widely used to secure web browsing (HTTPS), email, instant messaging, and other network services.
Developers should learn and use TLS whenever they need to protect sensitive data transmitted over networks, such as passwords, financial information, or personal data, to prevent eavesdropping and man-in-the-middle attacks. It is essential for building secure web applications, APIs, and any client-server communication that requires confidentiality and integrity, especially in compliance with standards like GDPR or PCI-DSS.
