Zoro - The masked avenger

Zoro is a data masking and anonymization utility. It fetches data from a database or a CSV file, and either creates a CSV file or runs SQL statements with the masked data.

It can be used as a command line program or as a dotnet standard 2.1 library. To run the command line program, simply copy the tools dir from the Nuget package. Windows and Linux versions, both 64-bit, are available.


As a command line utility:

[Win] zoro.exe path_to_config_file E.g. zoro.exe c:\temp\mask.xml

[Linux] ./zoro path_to_config_file E.g. zoro /home/jim/data/mask.xml

As a library

// === either read config from file ===
var configFromFile = Zoro.Processor.MaskConfig.ReadConfig("c:\temp\mask.xml");
// === or create in code ===
var config = new Zoro.Processor.MaskConfig()
    ConnectionString = "Server=myDbServer;Database=myDb;User Id=myUser;Password=myPassword;",
    ConnectionType = "System.Data.SqlClient",
    DataSource = DataSource.Database,
    DataDestination = DataDestination.CsvFile,
    SqlSelect = "SELECT * FROM testdata",
    OutputFile = Path.Combine(utility.TestInstanceDir, "maskeddata_db_02.csv")
config.FieldMasks.Add(new FieldMask() { FieldName = "name", MaskType = MaskType.Similar });
config.FieldMasks.Add(new FieldMask() { FieldName = "iban", MaskType = MaskType.Asterisk });
config.FieldMasks.Add(new FieldMask() { FieldName = "country", MaskType = MaskType.None });
config.FieldMasks.Add(new FieldMask() { FieldName = "address", MaskType = MaskType.List });
config.FieldMasks[3].ListOfPossibleReplacements.Add(new Replacement() 
    { Selector = "country=CH", ReplacementList="Bahnhofstrasse 41,Hauptstrasse 8,Berggasse 4" });
config.FieldMasks[3].ListOfPossibleReplacements.Add(new Replacement() 
    { Selector = "country=GR", ReplacementList="Evangelistrias 22,Thessalias 47,Eparhiaki Odos Lefkogion 6" });
// fallback when nothing matches; MUST be the last one
config.FieldMasks[3].ListOfPossibleReplacements.Add(new Replacement() 
    { Selector = "", ReplacementList="Main Street 9,Fifth Avenue 104,Ranch rd. 1" });         

// === with your config, call the masking method ===
var masker = new Zoro.Processor.DataMasking(config);

Sample config file:

<?xml version="1.0"?>
<MaskConfig xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

The above config file can process for example the following CSV:


and the result will be something like the following:


A more complete sample of a config file is the following:

<?xml version="1.0"?>
<MaskConfig xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
          <Replacement Selector="Country=Netherlands" List="Bergselaan,Schieweg,Nootdorpstraat,Nolensstraat" />
          <Replacement Selector="Country=Switzerland" List="Bahnhofstrasse,Clarahofweg,Sperrstrasse,Erlenstrasse" />
          <Replacement Selector="Country=Liechtenstein" List="Lettstrasse,Bangarten,Beckagässli,Haldenweg" />
          <Replacement Selector="Country=Germany" List="Bahnhofstraße,Freigaße,Hauptstraße" />
          <Replacement Selector="Country=Belgium" List="Rue d'Argent,Rue d'Assaut,Rue de l'Ecuyer,Rue du Persil" />
          <Replacement Selector="Country=Austria" List="Miesbachgasse,Kleine Pfarrgasse,Heinestraße" />
          <Replacement Selector="Country=France" List="Rue Nationale,Boulevard Vauban,Rue des Stations,Boulevard de la Liberté" />
          <Replacement Selector="" List="Bedford Gardens,Sheffield Terrace,Kensington Palace Gardens" />
      <QueryReplacement SelectorField="CountryISOCode" GroupField="countrycode" ValueField="cityname" Query="SELECT cityname, countrycode FROM cities" />
  <SqlSelect>SELECT * FROM customers</SqlSelect>
  <SqlCommand>INSERT INTO customers_anonymous (ID, MainPhone, Street) VALUES ($ID, $MainPhone, $Street)</SqlCommand>

If using a database to write data (DataDestination=Database), the number of parameters in SqlCommand ($field) must match the number of FieldMasks.
