Abstract: A method of creating and using a virtual private network (VPN) client encrypts network communications to server/gateways using strong algorithms to ensure data integrity and privacy during transport. Transport uses standard HTTP packets. Encryption and integrity are provided by using Secure Socket Layer (SSL, sometimes referred to as TLS). This invention is compatible and portable to different computer operating systems and mobile devices, and is also lightweight, allowing for ‘clientless’ installation and removal or small-footprint (thin) client software installations. The invention can also secure mobile user communication links over public wireless hotspots or wired Internet links.
