Zero-Trust Software Licensing & Identity Architecture
NineAuth provides compiled software developers and native SaaS teams with an end-to-end security backbone: from hardware-locked license keys to memory-hard password hashing and sub-50ms cascade revocations.
Authentication API & Identity
Replace vulnerable client-side credentials with Argon2id password hashing, opaque 256-bit token entropy, and secure server-side session binding.
- ›Memory-hard Argon2id password verification
- ›Opaque 256-bit bearer tokens stored via SHA-256
- ›Native SDKs for C#, C++, Rust, and Electron
Software Licensing Engine
Issue, validate, and manage software license keys at scale. Support lifetime keys, subscription renewals, seat limits, and granular version gating.
- ›Cryptographic activation and seat quota enforcement
- ›Time-limited licenses with automatic expiry checks
- ›Dynamic feature flags mapped directly to license tiers
Hardware ID (HWID) Locking
Bind license activations to individual machines using non-reversible one-way cryptographic hashes of motherboard, CPU, and disk serial numbers.
- ›Zero-reconstruction privacy-preserving hashes
- ›Configurable self-service HWID reset quotas
- ›Instant prevention of unauthorized multi-PC sharing
Access Control & Entitlements
Evaluate permissions and feature tiers dynamically in-memory. Change pricing plans or unlock features without shipping binary updates.
- ›Zero client-side authorization hardcoding
- ›Instant plan upgrades and capability unlocks
- ›Microsecond in-memory entitlement lookups
Instant Cascade Revocation
When a license is revoked, refunded, or suspended, immediately terminate all active runtime sessions and refresh tokens globally.
- ›Sub-50ms propagation to runtime authorization nodes
- ›Immediate binary execution termination
- ›Automated kill-switch triggers on suspicious tampering
HMAC-SHA256 Webhooks
Synchronize license lifecycle events with your Discord bot, CRM, database, or billing system using cryptographically signed webhooks.
- ›HMAC-SHA256 signature verification on every payload
- ›Automatic retry queues with exponential backoff
- ›Comprehensive event payload logs and delivery tracing
