When a host request a page from server, the server will 1st bind a encryption key to the host's mac address. Data provided by host will be encrypted at the client side using the same encryption key. The encrypted data submitted by the host will be decrypt by the server. This is what i am trying to do.
I would like to know how do i get the mac address of a requesting host?
I am not familiar with asp.net. How should i encrypt the data at client side? Should i use client side scripting like javascript or is there an alternative for me to do it using C#?
