How to encrypt URL In Mvc

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

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;
}

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.
