使用实例：

private string urlPath = "";

protected void Page_Load(object sender, EventArgs e)

{

    if (!Page.IsPostBack)

    { 

        urlPath = Server.MapPath("~/file/");

        encryptInfo();

    }

}

/// <summary>

/// 字符串加密解密

/// </summary>

   public class CryptoUtil

   {

       //随机选8个字节既为密钥也为初始向量

       private static byte[] KEY_64 = { 42, 16, 93, 156, 78, 4, 218, 32 };

       private static byte[] IV_64 = { 55, 103, 246, 79, 36, 99, 167, 3 };

//加密算法的方法
const string KEY_64 = "VavicApp";//注意了，是8个字符，64位
const string IV_64 = "VavicApp";
public string Encode(string data)
{
byte[] byKey = System.Text.ASCIIEncoding.ASCII.GetBytes(KEY_64);
byte[] byIV = System.Text.ASCIIEncoding.ASCII.GetBytes(IV_64);
