Overview#

In Cryptography, Certificate Authority (CA) is an entity that issues digital Certificates.

The digital Certificate certifies the ownership of a Public Key by the named subject of the Certificate.

This allows Relying Party to rely upon signatures or assertions made by the Private Key that corresponds to the Public Key that is certified.

In this model of trust relationships, a Certificate Authority is a trusted third party that is trusted by both the subject (owner) of the certificate and the Relying Party upon the certificate.

Certificate Authoritys are characteristic of many Public Key Infrastructure (PKI) schemes.[1]

The user is responsible for going through the step of Certificate Validation for a certificate with a Certificate Authority to figure out if the certificate presented is valid.

Each Certificate Authority must have a CAPK and available to the end-user or device to perform the Certificate Validation of any Certificates.
