asp.netmvc剑道ui网格加密列数据

Question

    var grid = $("#grid").kendoGrid({
            dataSource: dataSource,
            pageable: true,
            height: 430,
            toolbar: ["create"],
            columns: [
            "ProductName", {
                field: "ID",
                title: "Product ID",
                width: "100px"
                }, {
                field: "UnitPrice",
                title: "Unit Price",
                format: "{0:c}",
                width: "100px"
                }, {
                field: "UnitsInStock",
                title: "Units In Stock",
                width: "100px"
                }, {
                field: "Discontinued",
                width: "100px"
                }, {
                command: ["edit", "destroy"],
                title: " ",
                width: "172px"
            }
            ],
            editable: "inline"
        }).data("kendoGrid");

如何加密列产品ID在Kendo ui网格用户看不到我的真实ID？我使用ASP. NET MVC 5。

谢谢你！

在将数据加载到代码中之前先注册数据，然后再绑定数据。

要做到这一点，请使用encrpyt类，如下所示

public class DataEncryptor
{
    TripleDESCryptoServiceProvider symm;

    #region Factory
    public DataEncryptor()
    {
        this.symm = new TripleDESCryptoServiceProvider();
        this.symm.Padding = PaddingMode.PKCS7;
    }
    public DataEncryptor(TripleDESCryptoServiceProvider keys)
    {
        this.symm = keys;
    }

    public DataEncryptor(byte[] key, byte[] iv)
    {
        this.symm = new TripleDESCryptoServiceProvider();
        this.symm.Padding = PaddingMode.PKCS7;
        this.symm.Key = key;
        this.symm.IV = iv;
    }

    #endregion

    #region Properties
    public TripleDESCryptoServiceProvider Algorithm
    {
        get { return symm; }
        set { symm = value; }
    }
    public byte[] Key
    {
        get { return symm.Key; }
        set { symm.Key = value; }
    }
    public byte[] IV
    {
        get { return symm.IV; }
        set { symm.IV = value; }
    }

    #endregion

    #region Crypto

    public byte[] Encrypt(byte[] data) { return Encrypt(data, data.Length); }
    public byte[] Encrypt(byte[] data, int length)
    {
        try
        {
            // Create a MemoryStream.
            var ms = new MemoryStream();

            // Create a CryptoStream using the MemoryStream 
            // and the passed key and initialization vector (IV).
            var cs = new CryptoStream(ms,
                symm.CreateEncryptor(symm.Key, symm.IV),
                CryptoStreamMode.Write);

            // Write the byte array to the crypto stream and flush it.
            cs.Write(data, 0, length);
            cs.FlushFinalBlock();

            // Get an array of bytes from the 
            // MemoryStream that holds the 
            // encrypted data.
            byte[] ret = ms.ToArray();

            // Close the streams.
            cs.Close();
            ms.Close();

            // Return the encrypted buffer.
            return ret;
        }
        catch (CryptographicException ex)
        {
            Console.WriteLine("A cryptographic error occured: {0}", ex.Message);
        }
        return null;
    }

    public string EncryptString(string text)
    {
        return Convert.ToBase64String(Encrypt(Encoding.UTF8.GetBytes(text)));
    }

    public byte[] Decrypt(byte[] data) { return Decrypt(data, data.Length); }
    public byte[] Decrypt(byte[] data, int length)
    {
        try
        {
            // Create a new MemoryStream using the passed 
            // array of encrypted data.
            MemoryStream ms = new MemoryStream(data);

            // Create a CryptoStream using the MemoryStream 
            // and the passed key and initialization vector (IV).
            CryptoStream cs = new CryptoStream(ms,
                symm.CreateDecryptor(symm.Key, symm.IV),
                CryptoStreamMode.Read);

            // Create buffer to hold the decrypted data.
            byte[] result = new byte[length];

            // Read the decrypted data out of the crypto stream
            // and place it into the temporary buffer.
            cs.Read(result, 0, result.Length);
            return result;
        }
        catch (CryptographicException ex)
        {
            Console.WriteLine("A cryptographic error occured: {0}", ex.Message);
        }
        return null;
    }

    public string DecryptString(string data)
    {
        return Encoding.UTF8.GetString(Decrypt(Convert.FromBase64String(data))).TrimEnd('\0');
    }

    #endregion

}

并像这样使用它：

string message="A very secret message here.";
DataEncryptor keys=new DataEncryptor();
string encr=keys.EncryptString(message);

// later
string actual=keys.DecryptString(encr);

Answer 2

可以对列使用kendo grid client模板，而不是直接加密，在该列中，您将Id值传递给javascript函数，然后使用算法对其进行加密并返回。差不多。

columns.Bound(client => client.Id).ClientTemplate("#=Encrypt(Id)#");

而且

 <script> 
function Encrypt(id)
{
// Logic to Encrypt ID
return encryptedID.toString();
}
</script>

如果这只是为了显示给用户那么这个解决方案的工作原理

第二种解决方案是只隐藏列（我的意思是没有必要向用户显示ID）

如果您觉得这有帮助，请标记为答案
