Public Key Certificate
Public key certificates are used by certain programs (such as web browsers and personal encryption programs) to ensure that a secure web site is legitimate. When a certificate authority (such as VeriSign, Comodo, or Network Solutions) receives a certificate request from a website operator, it confirms the web domain and contact information in the request match those on public record with a domain name registrar. If the information matches, then a public key certificate is issued to the website operator to place on a website.
