//string workingKey = "**********************";//put in the 32bit alpha numeric key in the quotes provided here
CCACrypto ccaCrypto = new CCACrypto();
string encResponse = ccaCrypto.Decrypt(Request.Form["encResp"], workingKey);
NameValueCollection Params = new NameValueCollection();
//string[] segments = encResponse.Split('&');
string ShipmetidArray = encResponse.Split('&')[0];
string Shipmentid = ShipmetidArray.Split('=')[1];
string RightsArray = encResponse.Split('&')[26];
string Rights = RightsArray.Split('=')[1];
string ClientIdArray = encResponse.Split('&')[27];
string ClientId = ClientIdArray.Split('=')[1];
string UsernameArray = encResponse.Split('&')[28];
string Username = UsernameArray.Split('=')[1];
Session["CLIENTID"] = ClientId;
Session["RIGHTS"] = Rights;
Session["USERNAME"] = Username;
string Month = DateTime.Now.ToString("MMM").ToUpper();
i searched more than 3 hours but i didn't get answer. Please tell how to slove this. I am waiting for your reply
