    }

推荐答案

检查此HTTP模块是否允许您在此处加密整个查询字符串 http://madskristensen.net/post/HttpModule-for-query-string-encryption.aspx [ ^ ]



问候

Check this HTTP module out that lets you encrypt the entire query string here at http://madskristensen.net/post/HttpModule-for-query-string-encryption.aspx[^]

使用C＃加密和解密数据 [ ^ ]



谢谢

Please follow the link below

Encrypt and Decrypt Data with C#[^]

Thanks

private static string EncryptionKey = "!#853g`de";
private static byte[] key = { };
private static byte[] IV = { 0x12, 0x34, 0x56, 0x78, 0x90, 0xAB, 0xCD, 0xEF };

//Encryption Technique:

public string Encrypt(string Input)
        {
          try
           {
                key = System.Text.Encoding.UTF8.GetBytes(EncryptionKey.Substring(0, 8));
                DESCryptoServiceProvider des = new DESCryptoServiceProvider();
                Byte[] inputByteArray = Encoding.UTF8.GetBytes(Input);
                MemoryStream ms = new MemoryStream();
                CryptoStream cs = new CryptoStream(ms, des.CreateEncryptor(key, IV), CryptoStreamMode.Write);
                cs.Write(inputByteArray, 0, inputByteArray.Length);
                cs.FlushFinalBlock();
                return Convert.ToBase64String(ms.ToArray());
          }
         catch (Exception ex)
         {
           return "";
         }
       }

//Decryption Technique :

public string Decrypt(string Input)
        {
            Byte[] inputByteArray = new Byte[Input.Length];

            try
            {
                key = System.Text.Encoding.UTF8.GetBytes(EncryptionKey.Substring(0, 8));
                DESCryptoServiceProvider des = new DESCryptoServiceProvider();
                inputByteArray = Convert.FromBase64String(Input);
                MemoryStream ms = new MemoryStream();
                CryptoStream cs = new CryptoStream(ms, des.CreateDecryptor(key, IV), CryptoStreamMode.Write);
                cs.Write(inputByteArray, 0, inputByteArray.Length);
                cs.FlushFinalBlock();
                Encoding encoding = Encoding.UTF8;
                return encoding.GetString(ms.ToArray());
            }
            catch (Exception ex)
            {
                return "";
            }
        }
