CA Signed Certificate
A CA signed certificate is a digital certificate issued by a trusted Certificate Authority (CA) that verifies the identity of a website, server, or entity and enables secure encrypted communication via protocols like HTTPS. It contains public key information, identity details, and the CA's digital signature to establish trust in online interactions. These certificates are essential for implementing SSL/TLS encryption to protect data in transit and prevent man-in-the-middle attacks.
Developers should use CA signed certificates when deploying web applications, APIs, or any service requiring secure HTTPS connections to ensure data privacy, authentication, and compliance with security standards. They are critical for e-commerce sites, login systems, and sensitive data handling to build user trust and avoid browser security warnings. Learning this is necessary for configuring web servers, implementing SSL/TLS, and understanding public key infrastructure (PKI) in modern development.
