Question

我有两页两页。 MainPage.aspx和DealerPage.aspx

我从MainPage向DealerPage发送请求QueryString，但我想在传递给DealerPage时加密QueryString

在MainPage.aspx（Javascript）

              google.maps.event.addListener(marker2, "click", function (e) {

              infoWindow2.setContent(data2.description);
              infoWindow2.open(map2, marker2);
              window.location = "DealerPage.aspx?DI=" + data2.plate;
              icon: InitIcon


              });

E.g

             http:localhost/DealerPage.aspx?DI=485180610

在DealerPage.aspx.cs中，我得到并使用QueryString。

             private string tankerPlate = "";

             protected void Page_Load(object sender, EventArgs e)

            {

             this.truckPlate = this.Page.Request.QueryString["DI"];

             }

我不希望显示像DI = 485180610。

我希望DI =加密并解密以使用下一页。

试试这个

public static class Crypt
{
    // Must be random
    private static readonly byte[] key = new byte[24] { 1, 2, 3, 4, 5, 6, 7, 8, 9, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 0, 1, 2, 3, 4 };

    public static string Encrypt(string input)
    {
        byte[] inputArray = UTF8Encoding.UTF8.GetBytes(input);
        TripleDESCryptoServiceProvider tripleDES = new TripleDESCryptoServiceProvider();
        tripleDES.GenerateKey();
        tripleDES.Key = key;
        tripleDES.Mode = CipherMode.ECB;
        tripleDES.Padding = PaddingMode.PKCS7;
        ICryptoTransform cTransform = tripleDES.CreateEncryptor();
        byte[] resultArray = cTransform.TransformFinalBlock(inputArray, 0, inputArray.Length);
        tripleDES.Clear();
        return Convert.ToBase64String(resultArray, 0, resultArray.Length);
    }

    public static string Decrypt(string input)
    {
        byte[] inputArray = Convert.FromBase64String(input);
        TripleDESCryptoServiceProvider tripleDES = new TripleDESCryptoServiceProvider();
        tripleDES.Key = key;
        tripleDES.Mode = CipherMode.ECB;
        tripleDES.Padding = PaddingMode.PKCS7;
        ICryptoTransform cTransform = tripleDES.CreateDecryptor();
        byte[] resultArray = cTransform.TransformFinalBlock(inputArray, 0, inputArray.Length);
        tripleDES.Clear();
        return UTF8Encoding.UTF8.GetString(resultArray);
    }
}
