Trusting Certificates and CA Certificate Downloads
|
X.509 certificates for persons,
hosts or services are issued by Certificate Authorities (CAs). CA certificates are issued to Certificate Authorities, which are the entities which hand out certificates to end-users and sub-ordinate CAs. These certificates are part of the certification path used to establish the trust chain for a certificate. The public keys in the CA certificates are used to verify the digital signatures on the certificates and CRLs (Certificate Revocation Lists) issued by these CAs. Certificate Authorities come in two flavors, Root and Subordinate. Subordinate CAs have had their CA certificates issued by a higher-level Certificate Authority (and the Root CA is one at the top the heirarchy). The trust chain needed to validate a certificate includes the CA certificates for the Issuing CA, the Root CA and any Subordinate CAs between the Root and the Issuing CA (if any, as the Issuing CA can be a Root CA).
