I have followed an example online for this, however it seems that a lot of these articles do not give you everything you need. I am not sure why people post articles that are partial. Custom written code you will almost never find an answer for what the intended was supposed to be. As a beginner it makes it hard to learn and understand. It was not on this site either by the way. So I have 4 classes Crypto, CryptoValueProvider, CryptoValueProviderAttributes, and CryptoValueProviderFactory. And have registered the proper code in Global.asax. The blank area is in the Crypto class. What I would like to do is change www.somewebsite.com/users/edit/5 to be www.somewebsite.com/users/edit/ndvnq;owirwghbqasldkhgf. When a company admin changes or edits there information I would like it to be encrypted as so they cannot just change 5 to 10 and see someone else's info. This solution looks very good as far as not having to place a lot of code in several pages.
Below is the code I have:

Usage:

[CryptoValueProvider] // This is apparently all you have to do for this to work

public ActionResult UserEdit(int id)

{

  return View();

}

Crypto Class - Where my issue is - Need examples of what should go here

    public static class Crypto

    {

      public static string Encrypt(Dictionary<string, string> keyValue)

      {

        // encrypt query string key value pair



      }



      public static Dictionary<string, string> Decrypt(string encryptedText)

      {

        // decrypt encrypted query string into key value pair

      }

    }

CryptoValueProvider:

    public class CryptoValueProvider : IValueProvider

{

    RouteData routeData = null;

    Dictionary<string, string> dictionary = null;



    public CryptoValueProvider(RouteData routeData)

    {

        this.routeData = routeData;

    }



    public bool ContainsPrefix(string prefix)

    {

        if (this.routeData.Values["id"] == null)

        {

            return false;

        }



        this.dictionary = Crypto.Decrypt(this.routeData.Values["id"].ToString());



        return this.dictionary.ContainsKey(prefix.ToUpper());

    }



    public ValueProviderResult GetValue(string key)

    {

        ValueProviderResult result;

        result = new ValueProviderResult(this.dictionary[key.ToUpper()],

            this.dictionary[key.ToUpper()], CultureInfo.CurrentCulture);

        return result;

    }

}

CryptoValueProviderAttributes:

    public class CryptoValueProviderAttribute : FilterAttribute, IAuthorizationFilter

{

    public void OnAuthorization(AuthorizationContext filterContext)

    {

        filterContext.Controller.ValueProvider = new CryptoValueProvider(filterContext.RouteData);

    }

}

CryptoValueProviderFactory:

    public class CryptoValueProviderFactory : ValueProviderFactory

{

    public override IValueProvider GetValueProvider(ControllerContext controllerContext)

    {

        return new CryptoValueProvider();

    }

}

Global.asax:

    protected void Application_Start()

    {

        ValueProviderFactories.Factories.Insert(0, new CryptoValueProviderFactory());

    }

Thank you for your help... It is much appreciated.
