Enterprise-Grade License Security
Protect your licenses with industry-standard cryptographic signatures, hardware binding, and tamper detection.
Unbreakable protection—cryptographic security that stops pirates cold.
What You Get
RSA/ECDSA Signatures
Industry-standard cryptographic protection
Hardware Binding
Licenses locked to specific machines
Key Management
Secure key generation and rotation
Tamper Detection
Instant detection of modified licenses
Key Rotation
Update keys without breaking licenses
Secure Storage
Encrypted at rest and in transit
The Problem
-
Simple license keys can be shared or guessed
-
No way to verify license authenticity locally
-
Licenses can be copied between machines
-
Stored license data could be tampered with
The Solution
-
Cryptographic signatures prevent forgery
-
Local verification without server contact
-
Hardware fingerprinting prevents copying
-
Tamper detection catches any modification
Cryptographic Signatures
- RSA-2048 or ECDSA-P256 license signatures
- Offline verification using public key
- Signature includes all license terms
Hardware Binding
- Composite fingerprint from multiple hardware sources
- Tolerant of minor hardware changes
- Configurable binding strictness
Key Management
- Automatic key generation per product
- Key rotation without license invalidation
- HSM integration for enterprise
How It Works
A simple, secure, and scalable workflow designed for modern systems.
Key Generation
KeyManager generates a cryptographic key pair for your product. Private key is securely stored.
No manual configuration required. Works silently in the background.
License Signing
When licenses are created, they're signed with your private key, embedding all terms.
Designed for compliance, audits, and zero-trust environments.
Distribution
Licenses include the signature. Your application includes only the public key.
No manual configuration required. Works silently in the background.
Verification
SDK verifies signature locally using public key. Any tampering invalidates the license.
Designed for compliance, audits, and zero-trust environments.

Frequently Asked Questions
What cryptographic algorithms are used?
RSA-2048 or ECDSA-P256 for signatures. AES-256 for data encryption. SHA-256 for hashing.
Can licenses be forged?
No. Without your private key, valid signatures cannot be created. This is mathematically impossible with current technology.
What happens if my private key is compromised?
Key rotation allows you to issue new keys. Existing licenses can be migrated with a transition period.
Does hardware binding work on VMs?
Yes. VM-specific identifiers are used. You can configure binding strictness based on your requirements.
