i have a simple Jquery code which is for sending $.ajax request and passing the login information to controller to check for the login credentials. i want to encrypt the data. please let me know how can i do that?.

i am posting my Jquery code here to give you an idea.

=============

Jquery Login Button clcik event

$('#btnLogin').click(function (e) {
        var email = $('#Email').val();
        var Password = $('#Password').val();
        var postdata =
        {
            "Email": email,
            "Password": Password
        };
        $('.Loading').fadeIn(50);
        $.ajax({

            url: '@Url.Action("CheckLogin","Home")',
            data: postdata,
            success: function (msg) {
                var data = msg.split(':');
                $('#Result').html(data[0]);
                $('.Loading').fadeOut(50);
             },
            error: function (data) {

                $('#Result').html(data);
                $('.Loading').fadeOut(50);
            }

        });
        e.preventDefault();
    });

========================== as you can see i am passing the username & password in Ajax, when the request goes i can see my username and password in Firebug...
