What role does a Certificate Authority play in encryption?

A Certificate Authority (CA) plays a critical role in the realm of encryption by issuing digital certificates. These certificates serve as a means to validate and certify the authenticity of public keys. When a user or organization requests a digital certificate, the CA verifies their identity and then binds that identity to a public key by issuing the certificate. This process ensures that when someone receives a public key, they can trust that it truly belongs to who it claims to represent, thereby facilitating secure communication over potentially untrusted networks.

While managing keys, creating encryption standards, and regulating data transfer are important aspects of overall security and encryption frameworks, they do not fall within the specific function of a Certificate Authority. The focus of a CA is mainly on the issuance and management of digital certificates, which are essential for establishing trust in encrypted communications.
