SSL
SSL (Secure Sockets Layer) is a cryptographic protocol designed to provide secure communication over a computer network, primarily the internet. It establishes an encrypted link between a web server and a client (e.g., a browser), ensuring that data transmitted between them remains private and integral. SSL has been largely superseded by TLS (Transport Layer Security), but the term is still commonly used to refer to secure connections in general.
Developers should learn SSL/TLS to implement secure data transmission in applications, such as web servers, APIs, and email services, protecting sensitive information like passwords and payment details from eavesdropping and tampering. It is essential for compliance with security standards (e.g., HTTPS for websites) and building trust with users by enabling encryption and authentication.
