Certificate Authority
A Certificate Authority (CA) is a trusted third-party organization that issues digital certificates used to verify the identity of individuals, organizations, or devices in a network. The CA acts as a guarantor of the authenticity of the information contained in the certificate, which includes the public key of the certificate holder. The CA verifies the identity of the certificate holder before issuing the certificate, and the certificate holder can use the certificate to prove their identity to other parties in the network. The use of digital certificates issued by a CA is a key component of secure communication over the internet, as it enables parties to verify the identity of each other and establish secure encrypted connections.
