Gianged-DRM-v1

Learning Purpose Project

This project is designed as an educational exercise to understand and implement basic Digital Rights Management (DRM) concepts in C#/.NET. It serves as a hands-on learning experience to explore software protection mechanisms, licensing systems, and security concepts.

Educational Disclaimer: This project is created solely for learning purposes. It demonstrates basic DRM concepts and should not be used in production environments without proper security auditing and enhancements.

Learning Objectives

• Understand the fundamentals of software licensing and protection
• Learn about cryptographic techniques in software security
• Explore hardware fingerprinting and machine identification
• Implement basic anti-debugging and integrity checking mechanisms
• Practice software architecture patterns for security systems

Getting Started

Prerequisites

• .NET 8.0 SDK or later
• Visual Studio 2022 or VS Code
• Windows OS (for registry-based features)

Building the Project

# Clone the repository
git clone https://github.com/gianged/Gianged-DRM-v1.git
cd Gianged-DRM-v1

# Build the solution
dotnet build

# Run the application
dotnet run --project DRM

Key Concepts Covered

1. License Management

• License generation and validation
• Feature-based licensing
• Expiration handling

2. Hardware Fingerprinting

• Machine identification
• Hardware-based license binding
• System information collection

3. Cryptographic Protection

• License encryption/decryption
• Digital signatures
• Hash verification

4. Anti-Tampering Measures
