Greenmask VS ShellNewHandler

• Open source and free
  Greenmask is an open-source PostgreSQL database anonymization and synthetic data generation tool released under the Apache 2.0 license, so teams can use, inspect, and modify it without licensing fees or vendor lock-in.
• Referential integrity preservation
  It supports deterministic transformations and handles dependencies such as primary and foreign keys, so anonymized data stays consistent across related tables. This keeps the masked database usable for testing and development.
• Rich library of built-in transformers
  It ships with many transformers for masking, randomizing, hashing, and generating values, such as names, emails, dates, and UUIDs. It also supports custom and templated transformations, which makes it adaptable to different data types and compliance needs.
• Compatible with pg_dump/pg_restore workflows
  Greenmask is a drop-in-style utility that works with PostgreSQL's native dump and restore format, including parallel execution. It fits easily into existing backup, CI/CD, and environment-provisioning pipelines and can handle large databases efficiently.
• Flexible deployment and configuration
  It is a single Go binary that can run in Docker, Kubernetes, or CI pipelines. It is configured with simple YAML, which makes it easy to automate and to keep masking rules under version control.

Possible disadvantages

• PostgreSQL-focused
  Greenmask is primarily designed for PostgreSQL. Teams with MySQL, SQL Server, Oracle, or NoSQL databases cannot use it for their whole data estate and may need extra tools.
• Configuration requires manual effort
  Users must write and maintain YAML configs that define which columns get which transformers. For large or frequently changing schemas, this can be time-consuming and error-prone, and automatic discovery of sensitive data is limited.
• Command-line oriented with limited GUI
  The tool is mainly operated through the CLI and config files, with no full-featured graphical interface. This can be a barrier for less technical users such as data stewards or compliance staff.
• Younger project with a smaller community
  Compared with long-established data masking products, Greenmask has a smaller user base, fewer third-party integrations and tutorials, and a faster-changing feature set. Community support and enterprise-grade assurances may be more limited.
• Limited advanced governance features
  Enterprise capabilities such as built-in audit trails, centralized policy management, role-based access control, and compliance reporting are not as extensive as in commercial data masking platforms. Organizations with strict regulatory requirements may need to build supporting processes themselves.

• I recently got libreoffice, but now the new option in right click looks like a mess. Can someone help me get rid of them please?

  Use Shell New Handler. Run the portable app and simply untick the items you don't want to appear in your new context menu. Source: about 4 years ago

• This menu should be easy to add/remove programs to... Who is really creating Access Databases from this menu often enough to keep it here? (Not me!) Is there an easy way to edit this?

  I've always used ShellNewHandler for this. It's a really simple portable utility that allows you to remove most of the items from that menu. Tested it out on Windows 11 and it's still compatible. Source: over 5 years ago
