html has little value itself. it's just a mark up language.
there's no tool that effectively hides your html because there's little reason to do this. any tool requires two way encryption and some kind of decrypt software that your browser can run natively.
all these encryption tools will hide you code by obscurity. that may be enough for your need but it's the lowest level of security you can have.
most right mouse click disable scripts return false on the right click event to stop anything happening. if you hit the alt menu key to the right of your "start" key on windows you can get around this. it's that simple.
sorry to be a party pooper....
