Overview

Vampauth is a free key-system and licensing platform for Roblox script developers. You register a project, issue time-limited keys bound to players’ hardware, and monetize free keys through a checkpoint flow of ad/offer links.

What you get

Capability	Notes
License management	Create, revoke, expire. Full lifecycle per key.
HWID binding	Lock a key to the hardware that first activates it (up to 10 per key).
Checkpoint flow	Gate free keys behind a configurable number of ad/offer links.
Ad network integrations	Linkvertise, Lootlabs, and more over time.
Validation API	`POST /api/v1/key/check` — HMAC-signed requests and responses.
Reference client	Single-file Luau client that does the whole dance and fails closed.

How auth works

Two values from the project page: a public Project ID and a 48-hex auth secret. Clients sign each request with HMAC-SHA1 over the body fields; the server signs successful responses the same way, so a client can fail closed on forged replies. The auth secret is a bearer secret — it lives inside your obfuscated script and nowhere else.
