Developer & Cryptographic Reference (NOX1 Payload Schema, Ed25519 SPKI & Key Precedence Rules)
RECEIPT FORMAT SPECIFICATION
Offline License Token Structure (WebCrypto Ed25519 SPKI)
Noxport verifies license entitlements locally using a three-segment signed receipt format (NOX1.<payload_b64url>.<signature_b64url>):
NOX1.<payload>.<signature>Three-Part Token Envelope
| Segment | Placeholder | Offline Verification Behavior |
|---|---|---|
| Version Prefix | NOX1 | Identifies the receipt schema version for local parser routing. |
| Encoded Payload | <payload> | Base64URL-encoded JSON object (<payload_b64url>) carrying schema version, key identifier, entitlement tier, and timestamps. |
| Detached Signature | <signature> | Base64URL-encoded 64-byte Ed25519 signature (<signature_b64url>) verified locally via WebCrypto SPKI public key import without network calls. |
Structural Payload Fields ({ v: 1, kid, t, c, iat, exp, jti })
| Field Key | Expected Type / Enum | Local Verifier Semantics |
|---|---|---|
| v | 1 | Payload schema version integer; parser rejects unknown payload versions immediately. |
| kid | string (Key ID) | Selects the pinned Ed25519 SPKI public key from the local verifier keyring. |
| t | "PRO_ANNUAL" | "PRO_LIFETIME" | "CREDIT_PACK" | Entitlement tier corresponding to pro_annual, pro_lifetime, or pack_25 credit pack. |
| c | number (credits) | Initial export credit count when t === "CREDIT_PACK" (25); 0 for unlimited time-based/lifetime tiers. |
| iat | number (Unix epoch seconds) | Issued-at timestamp used for local receipt inspection and audit ordering. |
| exp | number (Unix epoch seconds; 0 for perpetual) | Expiration timestamp for PRO_ANNUAL entitlements; 0 for perpetual PRO_LIFETIME and CREDIT_PACK receipts. |
Accountless Key Precedence, Stacking & Graceful Expiration Rules
1. PRECEDENCE (PRO_LIFETIME > PRO_ANNUAL > CREDIT_PACK)
An active PRO_LIFETIME or non-expired PRO_ANNUAL license always takes precedence over metered CREDIT_PACK credits.
2. ADDITIVE CREDIT STACKING (CREDIT_PACK · c: 25)
Activating an additional 25-Export Credit Pack (jti-deduplicated) adds +25 to your existing local balance (currentCredits + 25).
3. GRACEFUL EXPIRATION FALLBACK (PRO_ANNUAL)
When a 365-day PRO_ANNUAL token reaches exp, the extension falls back to any remaining CREDIT_PACK balance, and then to the Free Forever Basic Tier (6 formats).
