Certificate Authority

Certificates are issued by Certificate Authorities (CAs), such as Verisign, Thawte, Baltimore, and others.

These certificate authorities validate the identity of the individual/entity before issuing the certificate. A

Certificate Authority signs all certificates that it issues with its private key and the CA certificate contains

the corresponding public key. A browser must contain this CA Certificate in its Trusted Root Library in

order to “trust” certificates signed by the CA's private key. For additional information, please see
