Custom Crypto Value Provider in ASP.NET Core MVC to support encrypted query string or route parameter. More detail on implementation here.
- Create action method and mark it with
CryptoValueProviderattribute or mark some of the parameter withFromCryptoattribute
[CryptoValueProvider]
public IActionResult Example1(int param1, string param2)
{
}
/*OR*/
public IActionResult Example2([FromCrypto]int param1, string param2, [FromCrypto]string param3)
{
}- Create parameter dictionary and encrypt it with
CryptoParamsProtector
public class HomeController : Controller
{
CryptoParamsProtector _protector;
public HomeController(CryptoParamsProtector protector)
{
_protector = protector;
}
public IActionResult Index()
{
var paramDictionary = new Dictionary();
paramDictionary.Add("param1", 1234.ToString());
paramDictionary.Add("param2", "Hello World!");
ViewBag.encryptedRouteParam1 = _protector.EncryptParamDictionary(paramDictionary);
return View();
}
}- Use encrypted string as route parameter to generate link
<a asp-controller="demo" asp-action="example1" asp-route-id="@ViewBag.encryptedRouteParam1"><h4>Example 1 Demo</h4></a>
