Below is a small sample that i tried. This is not the exact solution but it might be useful. There are several things you might have to take care
- when user enters characters
- when user selects the whole text and enters
- when the user presses backspace (select all and delete)
etc. ..

HTML

<html>
    <head>
        <title></title>
    </head>
<body>
    <textarea id="txtArea" class="TextArea" name="textarea"  maxlength="256"></textarea>
    <input type="button" value="Get Value" />
<script type="text/javascript" src="../Scripts/jquery-1.7.1.js"></script>
<script type="text/javascript">
    $(function ($) {
        var text;
        $('#txtArea').keyup(function (e) {
            if (text) {
                text += $(this).val().replace(stars.substring(0, stars.length - 1), "");
            } else {
                text = $(this).val().replace(stars.substring(0, stars.length - 1), "");
            }
            ShowCharacter();
        });

        var stars;
        $('#txtArea').keydown(function () {
            if (stars)
                stars += '*';
            else
                stars = '*'
        });

        function ShowCharacter() {
            $('#txtArea').val(stars)
        }

        $("input[type='button']").click(function () {
            alert(text);
        });

    });
</script>
 
</body>
</html>
