C++ Authentication
and License Keys

Obsidium is a self-hosted authentication and software license management platform for C++, C#, and desktop apps. Enforce license key checks, HWID binding, encrypted sessions, and bans before users reach protected features.

“Obsidium makes license management simple. The dashboard is easy to use, and everything feels fast and secure.”

The Obsidium Difference

Why developers choose Obsidium authentication

Built for desktop software teams that need more than a login form: license keys, HWID enforcement, encrypted SDK traffic, user bans, session control, and a developer dashboard in one platform.

End-to-End Encrypted HTTPS

All SDK traffic runs over HTTPS with full end-to-end encrypted payloads using X25519, XSalsa20, and Poly1305. Every request body is sealed before it leaves your application.

Built-in Anti-Tamper Protections

Our client libraries ship with anti-debug detection, virtual machine awareness, and runtime protections baked in — shutting down reverse-engineering attempts before they start.

Subscription-Based Discord Roles

Connect your Discord server and map roles to license tiers. End users who link Discord in the client portal receive roles automatically when their subscription is active — and Obsidium removes them when access ends.

Monetize with Ad-Reward Links

Let users earn free license keys through work.ink and similar providers — earning you a minimum of $25 per 1,000 completions, with built-in bypass protections.

Granular Per-Component HWID Binding

Unlike competitors who collapse identifiers into a single hash, Obsidium stores each HWID component separately for harder-to-spoof binding and surgical bans.

User Data Hashed at Rest

Sensitive user data — including IP addresses and hardware identifiers — is cryptographically hashed before storage. Raw data is never exposed.

Self-Service Client Portal

Give end-users a branded web portal to activate licenses online, view subscriptions, download loaders and files, and reset their own HWID when you enable it — fewer support tickets for your team.
