A full licensing spine, not a license-key regex.
Each layer is independent. Start with signed activation; add binding, sealing and server-side enforcement as the value you’re protecting grows. Turn on only what a given game actually needs.
Tamper-evident by construction
Ed25519 license files signed by AWS KMS — the private key never touches disk. Clients verify the signature offline, before trusting a single field.
One seat, one device
Hardware fingerprints bind an activation to a machine, with fuzzy re-matching so honest hardware changes don’t punish real customers.
Works on a plane
Signed leases and configurable fail-open windows keep licensed games running through outages, travel and air-gapped installs.
Code that ships encrypted
Encrypt high-value code paths so they unseal only with a valid, machine-bound key — a cracker has to recover that key or dump the code at runtime, not just flip an if (licensed).
Keep the crown jewels remote
Move the most valuable logic server-side, released through short-lived, signed capability tokens bound to one machine and one request. A client-side crack can’t patch out what never ships.
A graceful end-of-contract
A signed, perpetual release grant retires protection cleanly when an agreement ends — a defined exit, not a dead-man’s switch.
