Systems Programming Toolkit

A collection of C++ libraries for systems programming, memory management, cryptography, pattern scanning, and 3D mathematics. Built for educational purposes to demonstrate low-level programming concepts and optimization techniques.

⚠️ Important Notice: This is an educational project and is NOT intended for production use. The project lacks enterprise-grade security features and error handling required for production environments.

Educational Use & Limitations

NOT FOR PRODUCTION USE

This project is strictly for educational and demonstration purposes. It should NEVER be deployed in production environments due to the following limitations:

Security Limitations

• Basic Error Handling: Limited validation and error recovery
• No Thread Safety: Global variables without synchronization
• Platform Specific: Windows-only implementation
• Memory Safety: Manual resource management without comprehensive guards
• Privilege Requirements: Some functions require elevated permissions

Scalability & Reliability Issues

• No Logging System: Basic output without comprehensive monitoring
• Single-threaded: Most operations are not thread-safe
• No Configuration: Hardcoded values and paths
• Limited Testing: Educational test coverage, not production validation

Maintenance Status

• Educational Project: Designed for learning, not enterprise use
• No Active Maintenance: Not intended for ongoing development
• No Support: Community project without official support

Suitable Use Cases

This project IS suitable for:

• Learning Systems Programming: Understanding low-level Windows APIs
• Algorithm Study: Implementing Boyer-Moore, matrix math, cryptography
• Performance Analysis: Studying optimization techniques and benchmarking
• Educational Projects: Teaching C++ and systems programming concepts
• Code Reference: Understanding implementation patterns and techniques
