If the client is Dotnet enabled i.e. if the user's system has dotnet
framework redistributable installed, you can write a small dll file and
embed it in the page, which can take the querystring values, encrypt them
and send them to the server. The servers should decrypt the values and use
them. If you want sample code you may write to me.

The server should create an RSA Key and send the Public portion of the key
as a parameter to the dll and retain the Private key in the session
variable. The client will generate a DES Key and encrypt the data using the
DES Key and then send the encrypted data together with the DES Key, which
will be encrypted using the RSA Public Key from the server. (Quite a
tantalizing solution, isn't it?)
