Offline Verification
License verification works completely offline on your air-gapped systems
No Internet Required
Traditional software licensing requires periodic 'phone home' connections to verify license validity. This is incompatible with air-gapped security requirements.
Signando CA uses cryptographic signatures for license verification. Once you have your license file, verification happens entirely offline using public-key cryptography.
Key Benefits
- ✓ No network connection needed

How Offline Licensing Works

3. Verify Locally
The software verifies the license using our public key - no network needed.
