name: software-hardening-licensing
description: Professional-grade software protection, code hardening, and licensing management. Handles code obfuscation with PyArmor, DRM implementation, license key generation (RSA/AES), and subscription models. Use PROACTIVELY for commercializing desktop apps, protecting IP, or implementing secure licensing servers.

Use this skill when

  • •Preparing a Python application for commercial release.
  • •Protecting source code from reverse engineering or unauthorized access.
  • •Implementing license key validation (offline or online).
  • •Setting up trial modes, feature-gating, or subscription-based access.
  • •Hardening software against common bypass techniques.

Instructions

  • •Use PyArmor (latest) for advanced Python code obfuscation.
  • •Never store plain-text secrets or keys in the source code.
  • •Implement asymmetric encryption (RSA) for license signature verification.
  • •Combine code protection with environment binding (Hardware ID, MAC address).
  • •Always include a graceful fallback for licensing server downtime.

Capabilities

Code Protection & Obfuscation

  • •PyArmor Mastery: Obfuscating scripts, bundling dependencies, and runtime security.
  • •Cross-Platform Hardening: Windows-specific (PE), macOS (Mach-O), and Linux safety.
  • •Anti-Debugging: Implementing checks to detect debuggers or VM environments.
  • •Dependency Guarding: Protecting compiled .so / .pyd files.

Licensing Models

  • •Subscription Management: Integration with Stripe/Paddle for recurring billing.
  • •License Keys: Generating and validating cryptographically secure keys (RSA-2048+).
  • •Trial & Evergreen Models: Implementing time-based access and perpetual licenses.
  • •Feature Gating: Dynamically enabling/disabling UI features based on license tier.

DRM & Security

  • •Hardware Binding: Locking software to specific machines (Machine Fingerprinting).
  • •Online Activation: Building secure activation servers with FastAPI or Go.
  • •Offline Validation: Public-key verification for air-gapped systems.
  • •Tamper Detection: Verifying integrity of the executable and resource files.

IP Commercialization

  • •Packaging for Sales: Designing the installer (Inno Setup, NSIS, DMG) to include license EULA.
  • •Version Control per Tier: Managing different builds (Lite, Pro, Enterprise).
  • •Internal Audit Trails: Logging activation events (privacy-compliant).

Example Interactions

  • •"Obfuscate my PyQt app using PyArmor to prevent source code leaks."
  • •"Implement an RSA-based license key generator and validator in Python."
  • •"How do I bind this software to a specific hardware ID to prevent piracy?"
  • •"Set up a feature-gating system that unlocks 'Easy Mode' vs 'Pro Mode' via a license file."
