@MeyerDigitalCo

Hi there, I’m Pieter, owner of MDC (Meyer Digital Co.), with 9 years relevant experience building secure licensing, activation, and validation systems for commercial desktop software. For a Windows application, I’d structure the licensing subsystem around: • Signed license files (RSA/ECC public-key verification, no private key in client) • Hardware fingerprinting (stable, tamper-resistant, configurable strictness) • Offline & online activation modes • Grace period + renewal logic • Anti-tamper checks (basic anti-debug + integrity validation) • Optional license server API (REST) for seat management Implementation options: • C/C++ native (WinAPI + crypto library) • Hybrid C++ core + minimal Python tooling for key generation • Encrypted license payload (AES) signed with private key • Clear separation between validation layer and business logic Deliverables: • Licensing core module (clean, documented) • Key generation tool (internal use only) • Activation/validation workflow • Integration guide • Basic reverse-engineering resistance hardening Timeline: 7–10 days Budget: $220 fixed PS: I design licensing systems assuming attackers will inspect your binary — I build with that reality in mind.
