Software Licensing API for Developers
Protect compiled binaries, prevent license sharing, and automate key lifecycle management with a hardened server-side license server built for desktop, native, and on-premise applications.
The Problem with Client-Side Licensing
Traditional software licensing relies on client-side key validation functions that can be patched with simple NOP instructions in x64dbg or Ghidra. Public keys shipped inside binaries are extracted, and key algorithms are replicated in cracking tools.
The NineAuth Zero-Trust Solution
NineAuth moves all validation to secure edge servers. The application client only receives short-lived, cryptographically signed entitlement tokens bound directly to the user machine hardware identifier (HWID). No client algorithms to decompile.
Deterministic Runtime Integration
TypeScript / C# / C++import { NineAuthClient } from "@nineauth/sdk";
const client = await NineAuthClient.initialize({
applicationId: "app_live_90f2b8a",
environment: "production"
});
// Activate license key with automatic machine hardware binding
const license = await client.activateLicense({
licenseKey: "PRO-8FA1-902C-44B1",
deviceFingerprint: "hwid-sha256-e91b0f"
});
console.log(`License valid until: ${license.expiresAt}`);
console.log(`Active seats: ${license.usedSeats}/${license.maxSeats}`);
// Check dynamic entitlements in sub-millisecond memory
if (client.hasEntitlement("advanced_export")) {
renderProFeatures();
