from this i can understand that the parameters have been encrypted and the string which actually includes encrypted parameters passed as a parameter by itself. as i also understand, the server gets this "code" parameter and knows how to get the encrypted parameters from it. my questions are: 1. is there any common way this thing can be done in java? 2. i'm sure there are encryption classes, but if all this works the way i think, if encryption used we need to parse the unencrypted string of parameters and values with tokenizers or something, because there is no "request.getParameter("age")" way..
