The most common use of certificates is for HTTPS-based web sites. A web browser validates that an SSL (Transport Layer Security) web server is authentic; so that the user can feel secure that their interaction with the web site has no eavesdroppers and that the web site is who it claims to be. This security is important for electronic commerce. In practice, a web site operator obtains a certificate by applying to a certificate provider with a certificate signing request. The certificate request is an electronic document that contains the web site name, contact email address, and company information. The certificate provider signs the request, thus producing a public certificate. This public certificate is served to any web browser that connects to the web site and proves to the web browser that the provider believed that the provider issued a certificate to the owner of the web site. Before issuing a certificate, the certificate provider will request the contact email address for the web site from a public domain name registrar, and check that published address against the email address supplied in the certificate request. Therefore, an https web site is only secure to the extent that the end user can be sure that the web site is operated by someone in contact with the person that registered the domain name.
