Masquerade

This project is ABANDONED. Thanks for your support!

This project has been abandoned. For a better, faster and more maintained alternative, see Smile’s gdpr-dump. We have created our own repository for config files for popular Magento 2 extensions, see elgentos/gdpr-dump-magento-2-extensions.

Faker-driven, platform-agnostic, locale-compatible data faker tool

Point Masquerade to a database, give it a rule-set defined in YAML and Masquerade will anonymize the data for you
automatically!

Out-of-the-box supported frameworks

  • Magento 2
  • Shopware 6

Customization

You can add your own configuration files in a directory named config in the same directory as where you run masquerade. The configuration files will be merged with any already present configuration files for that platform, overriding any out-of-the-box values.

See the Magento 2 YAML files as examples for notation.

For example, to override the admin.yaml for Magento 2, you place a file in config/magento2/admin.yaml. For example, if you want to completely disable/skip a group, just add this content;

admin:

You can add your own config files for custom tables or tables from 3rd party vendors. Here are a few examples:

To generate such files, you can run the masquerade identify command. This will look for columns that show a hint of personal identifiable data in the name, such as name or address. It will interactively ask you to add it to a config file for the chosen platform.

Partial anonymization

You can affect only certain records by including a ‘where’ clause - for example to avoid anonymising certain admin accounts, or to preserve data used in unit tests, like this:

customers:
  customer_entity:
    provider: # this sets options specific to the type of table
      where: "`email` not like '%@mycompany.com'" # leave mycompany.com emails alone

Delete Data

You might want to fully or partially delete data - eg. if your developers don’t need sales orders, or you want to keep the database size a lot smaller than the production database. Specify the ‘delete’ option.

When deleting some Magento data, eg. sales orders, add the command line option --with-integrity which enforces foreign key checks, so for example sales_invoice records will be deleted automatically if their parent sales_order is deleted:

orders:
  sales_order:
    provider:
      delete: true
      where: "customer_id != 3" # delete all except customer 3's orders because we use that for testing
    # no need to specify columns if you're using 'delete'      

If you use ‘delete’ without a ‘where’, and without ‘–with-integrity’, it will use ‘truncate’ to delete the entire table. It will not use truncate if --with-integrity is specified since that bypasses key checks.

Magento EAV Attributes

You can use the Magento2Eav table type to treat EAV attributes just like normal columns, eg.

products:
  catalog_product_entity: # specify the base table of the entity
    eav: true
    provider:
      where: "sku != 'TESTPRODUCT'" # you can still use 'where' and 'delete'
    columns:
      my_custom_attribute:
        formatter: sentence
      my_other_attribute:
        formatter: email

  catalog_category_entity:
    eav: true
    columns:
      description: # refer to EAV attributes like normal columns
        formatter: paragraph

Formatter Options

For formatters, you can use all default Faker formatters.

Custom Data Providers / Formatters

You can also create your own custom providers with formatters. They need to extend Faker\Provider\Base and they need to live in either ~/.masquerade or .masquerade relative from where you run masquerade.

An example file .masquerade/Custom/WoopFormatter.php;

<?php

namespace Custom;

use Faker\Provider\Base;

class WoopFormatter extends Base {

    public function woopwoop() {
        $woops = ['woop', 'wop', 'wopwop', 'woopwoop'];
        return $woops[array_rand($woops)];
    }
}

And then use it in your YAML file. A provider needs to be set on the column name level, not on the formatter level.

customer:
  customer_entity:
    columns:
      firstname:
        provider: \Custom\WoopFormatter
        formatter:
          name: woopwoop

Custom Table Type Providers

Some systems have linked tables containing related data - eg. Magento’s EAV system, Drupal’s entity fields and Wordpress’s post metadata tables. You can provide custom table types.
In order to do it you need to implement 2 interfaces:

  • Elgentos\Masquerade\DataProcessorFactory is to instantiate your custom processor. It receives table service factory, output object and whole array of yaml configuration specified for your table.

  • Elgentos\Masquerade\DataProcessor is to process various operations required by run command like:

    • truncate should truncate table in provided table via configuration
    • delete should delete table in provided table via configuration
    • updateTable should update table with values provided by generator based on columns definitions in the configuration.
      See Elgentos\Masquerade\DataProcessor\RegularTableProcessor::updateTable for a reference.

First you need to start with a factory that will instantiate an actual processor

An example file .masquerade/Custom/WoopTableFactory.php;

<?php

namespace Custom;

use Elgentos\Masquerade\DataProcessor;
use Elgentos\Masquerade\DataProcessor\TableServiceFactory;
use Elgentos\Masquerade\DataProcessorFactory;
use Elgentos\Masquerade\Output;
 
class WoopTableFactory implements DataProcessorFactory 
{

    public function create(
        Output $output, 
        TableServiceFactory $tableServiceFactory,
        array $tableConfiguration
    ): DataProcessor {
        $tableService = $tableServiceFactory->create($tableConfiguration['name']);

        return new WoopTable($output, $tableService, $tableConfiguration);
    }
}

An example file .masquerade/Custom/WoopTable.php;

<?php

namespace Custom;

use Elgentos\Masquerade\DataProcessor;
use Elgentos\Masquerade\DataProcessor\TableService;
use Elgentos\Masquerade\Output;

class WoopTable implements DataProcessor
{
    /** @var Output */
    private $output;

    /** @var array */
    private $configuration;

    /** @var TableService */
    private $tableService;

    public function __construct(Output $output, TableService $tableService, array $configuration)
    {
        $this->output = $output;
        $this->tableService = $tableService;
        $this->configuration = $configuration;
    }

    public function truncate(): void
    {
        $this->tableService->truncate();
    }
    
    public function delete(): void
    {
        $this->tableService->delete($this->configuration['provider']['where'] ?? '');
    }
    
    public function updateTable(int $batchSize, callable $generator): void
    {
        $columns = $this->tableService->filterColumns($this->configuration['columns'] ?? []);
        $primaryKey = $this->configuration['pk'] ?? $this->tableService->getPrimaryKey();
        
        $this->tableService->updateTable(
            $columns, 
            $this->configuration['provider']['where'] ?? '', 
            $primaryKey,
            $this->output,
            $generator,
            $batchSize
        );
    }
}

And then use it in your YAML file. A processor factory needs to be set on the table level, and can be a simple class name, or a set of options which are available to your class.

customer:
  customer_entity:
    processor_factory: \Custom\WoopTableFactory
    some_custom_config:
      option1: "test"
      option2: false
    columns:
      firstname:
        formatter:
          name: firstName

Installation

Download the phar file:

curl -L -o masquerade.phar https://github.com/elgentos/masquerade/releases/latest/download/masquerade.phar

      --platform[=PLATFORM]
      --driver[=DRIVER]      Database driver [mysql]
      --database[=DATABASE]
      --username[=USERNAME]
      --password[=PASSWORD]
      --host[=HOST]          Database host [localhost]
