We’re thrilled to announce the first stable release of Licenz!
Highlights
Zero-Dependency Rust Client
The Licenz client is a single 2MB static binary that runs on any system. No JVM, no .NET runtime, no kernel drivers - just copy the binary and start validating licenses.
True Air-Gap Support
Unlike other solutions that bolt offline capabilities onto online-first systems, Licenz was designed from the ground up for disconnected environments. Our sneakernet workflow makes activation simple and secure.
Modern Cryptography
We use industry-standard cryptographic primitives:
- Ed25519 or RSA-SHA256 for license signatures
- AES-256-GCM for encrypted state storage
- Argon2id for key derivation
Open Source Client
The entire client library is MIT-licensed and open source. Your security team can audit every line before deploying to air-gapped networks.
Getting Started
Check out our quickstart guide to integrate Licenz in minutes.
use licenz::{LicenseVerifier, License};
let verifier = LicenseVerifier::new(PUBLIC_KEY)?
.with_hardware_binding();
let license = License::from_file("license.key")?;
let claims = verifier.verify(&license)?;
What’s Next
We’re actively working on:
- Additional language bindings (Python, Go, C/C++)
- Enhanced hardware binding options
- Self-hosted deployment guides
Thank you to everyone who participated in our beta program. Your feedback has been invaluable in shaping this release.
