Certificate Authority (CA)

A Certificate Authority (CA) is an external organization that issues certificates and manages the public keys necessary for verifying digital certificates in online environments. CAs play a crucial role in ensuring the security of information exchanged over the internet, and they can be either government entities or large multinational corporations. Digital certificates are frequently utilized to secure digital transactions and identity information, enabling the safe exchange of data online. Certificates that rely on protocols like Transport Layer Security (TLS) and Secure Sockets Layer (SSL) provide users with the ability to send instant messages and emails securely.
