HTTPS
HTTPS is an acronym for Hypertext Transfer Protocol Secure. It is Hypertext Transfer Protocol over Secure Socket Layer, or HTTP over SSL.
HTTPS is the web protocol that extends standard HTTP to support a secure way of sending data across the internet from a web server to a web browser. It provides encryption of data and identification for secure end to end communication.
HTTPS uses port 443 by default and requires the web browser to trust a certificate authority (such as VeriSign) to authenticate the web site certificate.
