Cold Coffee License Security

Model the license system as an entitlement and trust problem, not as one client-side comparison.

Start

1. Identify product, client, server, operator/admin, payment, key store, entitlement store, device identity, and update channel.
2. Trace issuance, activation, verification, refresh, revocation, transfer, expiration, and recovery flows.
3. Mark every client-controlled value and every decision made without server evidence.
4. Locate embedded secrets, public keys, signatures, clocks, caches, anti-replay fields, error paths, and offline grace behavior.

• Threats and reverse-analysis entry points: read references/threat-model.md.
• Secure online/offline design: read references/secure-design.md.
• Binary/client/API reverse audit: read references/reverse-audit.md.
• Operations, leakage, resale, revocation, and telemetry: read references/operations.md.

Tools

• Use scripts/license_tool.py to generate Ed25519 keys, issue signed license documents, and verify them in a reference implementation.
• Use scripts/audit_license_config.py to flag risky architecture choices in a JSON design/config description.
• Combine with $eni-reverse-deep, $eni-pentest-advanced, and $eni-case-lab for client binaries, activation APIs, and evidence.
