Byndyusoft.MaskedSerialization.Newtonsoft 3.0.0

Byndyusoft.MaskedSerialization

A tool to mask sensitive data during serialization with the System.Text.Json package

Installing

dotnet add package Byndyusoft.MaskedSerialization

Usage

If you use System.Text.Json to serialize data, use [Masked] attribute to mark properties that should be masked. Example:

  public class CompanyDto
  {
      public string Name { get; set; } = default!;

      [Masked]
      public string SecretOwner { get; set; } = default!;

      public IncomeDto WhiteIncome { get; set; } = default!;

      [Masked]
      public IncomeDto GreyIncome { get; set; } = default!;
  }

  public class IncomeDto
  {
      public string Description { get; set; } = default!;

      [Masked]
      public long SumInDollars { get; set; }
  }

Values of properties SecretOwner and GreyIncome of class CompanyDto will be masked with value "*". Here is an example of simple usage:

  var dto = new CompanyDto
                {
                    Name = "Mega Big Company",
                    SecretOwner = "Navalov",
                    WhiteIncome = new IncomeDto
                                      {
                                          Description = "White",
                                          SumInDollars = 1000000
                                      },
                    GreyIncome = new IncomeDto
                                     {
                                         Description = "Black",
                                         SumInDollars = 1000000000
                                     }
                };

  var serialized = MaskedSerializationHelper.SerializeWithMasking(dto);

The result will be:

{
   "Name":"Mega Big Company",
   "SecretOwner":"*",
   "WhiteIncome":{
      "Description":"White",
      "SumInDollars":"*"
   },
   "GreyIncome":"*"
}

You can setup serializer options to enable masking. Another usage example:

  var options = new JsonSerializerOptions();
  MaskedSerializationHelper.SetupSettingsForMaskedSerialization(options);
  var serialized = JsonSerializer.Serialize(dto, options);

Byndyusoft.MaskedSerialization.Newtonsoft

A tool to mask sensitive data during serialization with Newtonsoft.Json

Installing

dotnet add package Byndyusoft.MaskedSerialization.Newtonsoft

Usage

If you use Newtonsoft.Json to serialize data, use [Masked] attribute to mark properties that should be masked. Usage example:

  var serialized = MaskedSerializationHelper.SerializeWithMasking(dto);
  // Another usage example
  var settings = new JsonSerializerSettings();
  MaskedSerializationHelper.SetupSettingsForMaskedSerialization(settings);
  var serialized = JsonConvert.SerializeObject(dto, settings);

Byndyusoft.MaskedSerialization.Serilog

A tool to mask sensitive destructured data in logging with Serilog

Installing

dotnet add package Byndyusoft.MaskedSerialization.Serilog

Usage

You can setup logger configuration to use destructure masking policy:

  var loggerConfiguration = new LoggerConfiguration().WithMaskingPolicy().WriteTo.Console();

Here is an example of simple usage:

public class Service
{
  private readonly ILogger<Service> _logger;

  public Service(ILogger<Service> logger)
  {
    _logger = logger;
  }

  public void LogCompany()
  {
    var dto = new CompanyDto
                  {
                      Name = "Mega Big Company",
                      SecretOwner = "Navalov",
                      WhiteIncome = new IncomeDto
                                        {
                                            Description = "White",
                                            SumInDollars = 1000000
                                        },
                      GreyIncome = new IncomeDto
                                       {
                                           Description = "Black",
                                           SumInDollars = 1000000000
                                       }
                  };
    
    _logger.LogInformation("Used company {@CompanyDto}", dto);
  }
}

The output in the console will be:

  [10:47:31 INF] Used company {"Name": "Mega Big Company", "SecretOwner": "*", "WhiteIncome": {"Description": "White", "SumInDollars": "*", "$type": "IncomeDto"}, "GreyIncome": "*", "$type": "CompanyDto"}
