加密部分appConfig configSe c＃

Question

我有自定义配置部分与服务器设置，其中包括：服务器的用户名，密码和IP;我需要得到这种类型的加密配置：

<ApplicationServerConfiguration> 
    <Server UserName="ASDASDASDASDAS [Some encrypted value] ASDASDASF"/> 
    <Server Password="ASDASDASDASDAS [Some encrypted value] ASDASDASF"/> 
    <Server ServerAddress="192.168.255.255"/> **Not encrypted value!** 
</ApplicationServerConfiguration> 

我可以加密整个configSection，但不是它的一部分。谁知道如何加密configSection的部分内容？

Answer 1

不可能只加密部分的部分。如果您想要加密它们，您必须将用户名和密码值放入单独的部分。

Answer 2

App.config对于存储安全证书并不是一个好的地方！

Answer 3

您可以手动加密和解密他们

private static string EncryptString(string Value) 
    { 
     string ReturnValue = string.Empty; 

     MD5CryptoServiceProvider HashProvider = new MD5CryptoServiceProvider(); 
     byte[] TDESKey = HashProvider.ComputeHash(ASCIIEncoding.ASCII.GetBytes("Bermuda")); 

     using (TripleDESCryptoServiceProvider provider = new TripleDESCryptoServiceProvider()) 
     { 
      provider.Key = TDESKey; 
      provider.Mode = CipherMode.ECB; 
      provider.Padding = PaddingMode.PKCS7; 

      ICryptoTransform Encryptor = provider.CreateEncryptor(); 
      byte[] ByteValue = ASCIIEncoding.ASCII.GetBytes(Value); 

      ReturnValue = Convert.ToBase64String(Encryptor.TransformFinalBlock(ByteValue, 0, ByteValue.Length)); 
     } 

     return ReturnValue; 
    } 
    private static string DecryptString(string EncryptedValue) 
    { 
     string ReturnValue = string.Empty; 

     MD5CryptoServiceProvider HashProvider = new MD5CryptoServiceProvider(); 
     byte[] TDESKey = HashProvider.ComputeHash(ASCIIEncoding.ASCII.GetBytes("Bermuda")); 

     using (TripleDESCryptoServiceProvider provider = new TripleDESCryptoServiceProvider()) 
     { 
      provider.Key = TDESKey; 
      provider.Mode = CipherMode.ECB; 
      provider.Padding = PaddingMode.PKCS7; 

      ICryptoTransform Decryptor = provider.CreateDecryptor(); 
      byte[] ByteValue = Convert.FromBase64String(EncryptedValue); 

      ReturnValue = ASCIIEncoding.ASCII.GetString(Decryptor.TransformFinalBlock(ByteValue, 0, ByteValue.Length)); 
     } 

     return ReturnValue; 
    }
