Description: Well-known Certificate Authorities (such as Thawte and VeriSign) exist to serve as authoritative, trusted third-parties for authentication. They are in the business of signing SSL certificates that are used on sites that deal with sensitive information (like account numbers or passwords). If a site\'s SSL certificate is signed by a trusted authority, then presumably it is possible to verify the identity of a server supplying that certificate\'s credentials. In order to receive a certificate "blessed" by a well-known CA, you have to prove to them beyond a shadow of doubt that not only are you who you claim to be, but that you have the right to use the certificate in the way you intend to.
