What is a Certificate Authority?

A Certificate Authority (CA) is a trusted organization that issues, validates, renews, and revokes digital certificates. These certificates authenticate the identity of websites, servers, users, applications, and connected devices while enabling encrypted communication over the internet.

Certificate authorities form the backbone of Public Key Infrastructure (PKI) and are essential for maintaining trust in digital communications.

Digital certificates are commonly used for:

SSL/TLS website encryption
Email security
Code signing
Digital signatures
Identity verification
Device authentication
Secure cloud communications
VPN authentication
