Payment aware

Detached JWS verification and idempotent CorePort webhooks.

Key safe

Per-project private keys encrypted with AES-GCM and never returned.

Offline trust

Certificates match flutter_licensing’s Ed25519 trust model.

Multi-project

Independent tiers, currencies, slippage, and license policies.

Built for the entire license lifecycle.

Customer checkout, currency conversion, signed issuance, public-key rotation, capacity billing, renewal reminders, a five-day grace period, and deterministic suspension behavior.
