Asp.net Cookie Encyript ve Decrypt

Bu makalemde asp.net projesi içerisindeki cookieleri nasıl encyript ve decrypt yapıcağımızı göstereceğim. Bunun için ise “MachineKey.Protect” and “MachineKey.Unrotect” methodlarını kullanacağız.

Encrypt Cookies:

//using System.Text;
//using System.Web.Security;

var cookieText = Encoding.UTF8.GetBytes("Text for Cookie");
var encryptedValue = Convert.ToBase64String(MachineKey.Protect(cookieText, "ProtectCookie"));

//--- Create cookie object and pass name of the cookie and value to be stored.
HttpCookie cookieObject = new HttpCookie("NameOfCookie", encryptedValue);

//---- Set expiry time of cookie.
cookieObject.Expires.AddDays(5);

//---- Add cookie to cookie collection.
Response.Cookies.Add(cookieObject);

Decrypt Cookies:

 
var bytes = Convert.FromBase64String(Request.Cookies["NameOfCookie"].Value);
var output = MachineKey.Unprotect(bytes, "ProtectCookie");
string result = Encoding.UTF8.GetString(output);
