问题描述

大家好，



i想要这样假设我有网址http：// localhost / myApp / api / Password / 435





i想要ecode 435到AL2uJOIm1CI =或者是一些无法理解的东西，比如http：// localhost / myApp / api / Password / AL2uJOIm1CI =



以及如何解码AL2uJOIm1CI =再次435

Hi All,

i want like this suppose i have url http://localhost/myApp/api/Password/435


i want ecode 435 to AL2uJOIm1CI= or somthing that can be not understandable , like http://localhost/myApp/api/Password/AL2uJOIm1CI=

and how to decode AL2uJOIm1CI= to again 435

推荐答案

您可以在将值传递给url然后解密之前对其进行加密它在你的页面中。

这是一个加密和解密值的例子：



加密值：

You can encrypt your value before passing it to url and then decrypt it in your page.
Here is an example of encrypting and decrypting value :

encrypting value :

public static string Encrypt_QueryString(string str)
   {
       string EncrptKey = "2013;[pnuLIT)WebCodeExpert";
       byte[] byKey = { };
       byte[] IV = { 18, 52, 86, 120, 144, 171, 205, 239 };
       byKey = System.Text.Encoding.UTF8.GetBytes(EncrptKey.Substring(0, 8));
       DESCryptoServiceProvider des = new DESCryptoServiceProvider();
       byte[] inputByteArray = Encoding.UTF8.GetBytes(str);
       MemoryStream ms = new MemoryStream();
       CryptoStream cs = new CryptoStream(ms, des.CreateEncryptor(byKey, IV), CryptoStreamMode.Write);
       cs.Write(inputByteArray, 0, inputByteArray.Length);
       cs.FlushFinalBlock();
       return Convert.ToBase64String(ms.ToArray());
   }

解密价值：

Decrypting value :

public static string Decrypt_QueryString(string str)
    {
        string strreturn = string.Empty;
        try
        {
            str = str.Replace(" ", "+");
            string DecryptKey = "2013;[pnuLIT)WebCodeExpert";
            byte[] byKey = { };
            byte[] IV = { 18, 52, 86, 120, 144, 171, 205, 239 };
            byte[] inputByteArray = new byte[str.Length];

            byKey = System.Text.Encoding.UTF8.GetBytes(DecryptKey.Substring(0, 8));
            DESCryptoServiceProvider des = new DESCryptoServiceProvider();
            inputByteArray = Convert.FromBase64String(str);
            MemoryStream ms = new MemoryStream();
            CryptoStream cs = new CryptoStream(ms, des.CreateDecryptor(byKey, IV), CryptoStreamMode.Write);
            cs.Write(inputByteArray, 0, inputByteArray.Length);
            cs.FlushFinalBlock();
            System.Text.Encoding encoding = System.Text.Encoding.UTF8;
            strreturn = encoding.GetString(ms.ToArray());

        }
        catch (Exception ex)
        {
            //throw ex;
            ex.Message.ToString();
        }
        return strreturn;
    }

不要忘记包含以下名称空间：

Do not forget to include following name space :

using System.Security.Cryptography;
