  • Customer portal: purchase/claim product, view licenses, copy keys, request transfers.
    • 

  • One-click activation: license key + device fingerprint (CPU/UUID/mac address optional) -> server issues activation token.
    • 

  • Offline activation: challenge/response file and signed license blob for air-gapped devices.
    • 

  • License types: trial (time-limited), node-locked (hardware-bound), floating (concurrent seat pool), subscription (time & usage-based), feature flags (enable/disable modules).
    • 

  • Automatic renewals & grace periods: configurable reminders, grace window after expiry, auto-disable after final expiry.
    • 

  • Admin UI: create products/plans, issue/manual keys, revoke, blacklist, view audit log.
    • 

  • Usage & analytics: per-license activation history, active device list, monthly active users, geo/IP map.
    • 

  • Security: HMAC-signed license blobs (server secret), optional asymmetric signing (RSA/ECDSA) for verification without server, rate limiting, brute-force protection, encrypted DB fields for secrets.
    • 

  • GitHub-friendly installer: single Composer package + Artisan commands or setup script to scaffold DB tables, config, and webhooks.
    • 

  • Webhooks & API: events for activation, renewal, revoke; REST API for integrations (billing, CI/CD).
    • 

  • Adminful CLI: issue/revoke keys, bulk-import, generate offline licenses.
    • 

  • Multi-tenant & white-label support: per-customer branding and custom domains.
    • 

  • Tests & CI: unit/integration tests included; GitHub Actions to run migrations, linting, and package releases.
    • 

  • Docs & examples: sample PHP client SDK (cURL and Guzzle), sample client-side verification code, and how-to for common flows.
    • 



Most modern systems use cryptographic signing. You must generate a root certificate or key pair for signing your license keys: masterix21/laravel-licensing - GitHub php license key system github install
