EzJsonAnonymizer 1.0.0

EzJsonAnonymizer

Nuget package name: EzJsonAnonymizer

The easiest way to anonymize json fields (thinking about PIIs and GDPR)

Example input:

{
  "Account": "32984902348",
  "Name": "Wilson",
  "Cpf": "329048329",
  "Rg": "359034905",
  "Documents": {
    "Cnh": "3290843289",
    "UF": "SP"
  },
  "DocumentsArray": [
    {
      "Cnh": "3290843289",
      "UF": "SP"
    },
    {
      "Cnh": "3290843289",
      "UF": "SP"
    }
  ]
}

The code:

var exampleJson = // the json above
var anonymizer = new EzJsonAnonymizer(new string[] { "Name", "Cnh" }, ListTypes.WhiteList);
var output = anonymizer.Anonymize(exampleJson);
// the output will be the json below

The output:

{
  "Account": "******",
  "Name": "Wilson",
  "Cpf": "******",
  "Rg": "******",
  "Documents": {
    "Cnh": "3290843289",
    "UF": "******"
  },
  "DocumentsArray": [
    {
      "Cnh": "3290843289",
      "UF": "******"
    },
    {
      "Cnh": "3290843289",
      "UF": "******"
    }
  ]
}

Simple like that! 🎉

You can use whitelist, so all the fields that aren`t in the list will be anonymized; or you can use the blacklist, so only the fields in the list will be anonymized.

See below the properties of the construtor:

// the constructor
public EzJsonAnonymizer(
  IEnumerable<string> propertiesList, // the list of properties to be processed (it`s case insensitive)
  ListTypes listType = ListTypes.BlackList, // the type of list: whitelist or blacklist?
  int numberOfCharactersOnMask = 6,  // number of characters in the mask
  char maskCharacter = '*' // the character used for the mask
)

I hope it helps you and you enjoy it. Feel free to open issues or PRs.
