Hi, You have to use methods for encrypt and decrypt the url use below function. or u can create your own class library and use it. Or you can see the http://getcodesnippet.com/2015/11/03/how-to-encrypt-and-decrypt-url-or-data-using-c-in-asp-net-mvc/ using System; using System.Collections.Generic; using System.IO; using System.Linq; using System.Security.Cryptography; using System.Text; using System.Web; namespace MyApp.Common { public class Security { static readonly char [] padding = { '=' }; public static string Encrypt( string clearText) { try { string EncryptionKey = "JHK@!$RTYEWQRGH" ; byte [] clearBytes = Encoding.Unicode.GetBytes(clearText); using (Aes encryptor = Aes.Create()) { Rfc2898DeriveBytes pdb = new Rfc2898DeriveBytes(EncryptionKey, new byte [] { 0x49, 0x76, 0x61, 0x6e, 0x20, 0x4d, 0x65, 0x64, 0x76, 0x65, 0x64, 0x65, 0x76 }); encryptor.Key = pdb.GetBytes(32); encryptor.IV = pdb.GetBytes(16); using (MemoryStream ms = new MemoryStream()) { using (CryptoStream cs = new CryptoStream(ms, encryptor.CreateEncryptor(), CryptoStreamMode.Write)) { cs.Write(clearBytes, 0, clearBytes.Length); cs.Close(); } clearText = Convert.ToBase64String(ms.ToArray()).TrimEnd(padding).Replace( '+' , '-' ).Replace( '/' , '_' ); } } return clearText; } catch { } return "" ; } public static string Decrypt( string cipherText) { string incoming = cipherText.Replace( '_' , '/' ).Replace( '-' , '+' ); switch (cipherText.Length % 4) { case 2: incoming += "==" ; break ; case 3: incoming += "=" ; break ; } try { string EncryptionKey = "JHK@!$RTYEWQRGH" ; byte [] cipherBytes = Convert.FromBase64String(incoming); using (Aes encryptor = Aes.Create()) { Rfc2898DeriveBytes pdb = new Rfc2898DeriveBytes(EncryptionKey, new byte [] { 0x49, 0x76, 0x61, 0x6e, 0x20, 0x4d, 0x65, 0x64, 0x76, 0x65, 0x64, 0x65, 0x76 }); encryptor.Key = pdb.GetBytes(32); encryptor.IV = pdb.GetBytes(16); using (MemoryStream ms = new MemoryStream()) { using (CryptoStream cs = new CryptoStream(ms, encryptor.CreateDecryptor(), CryptoStreamMode.Write)) { cs.Write(cipherBytes, 0, cipherBytes.Length); cs.Close(); } cipherText = Encoding.Unicode.GetString(ms.ToArray()); } } return cipherText; } catch { } return "" ; } } }

You can't encrypt a URL entirely otherwise its a bunch of gibberish to the browser. What you can do is something like taking this URL http://localhost/home/id (http://localhost/home/1) Then encrypting id http://localhost/home/encryp-id (http://localhost/home/lkewhrgkljhergkjh) Then in your controller, using the Id in the url past into the controllers action, you would decrypt that value and go about loading the page accordingly.
