    I did not try it, but logically, you should be able to use
    HttpUtility.UrlEncode and HttpUtility.UrlDecode to convert encrypted bytes
    to/from query-string compatible form. Alternatively, you can convert
    encrypted data into a base64-encoded string and append it as a last query
    string parameter. In the last scenario, you would need to treat it
    differently from a regular QueryString value by manually locating the
    beginning of the string (you must make sure that the name of the value is
    unique) and extracting the substring from beginning position till the end.
